For some reason I have to restart my PC to be able to use my keyboard. It boots up perfectly fine except the fact I cant type on it from a cold start. I tried replugging in the keyboards and it doesnt help. This is a problem with all 3 of my IBM keyboards. I tried with my steelseries 7G and its fine. I'm solely using my PS/2. Does anyone know whats the problem?
-
You're not hot-swapping the keyboards, right? The PS/2 bus doesn't like hot swapping, and will usually lock up until the PC is rebooted if you try.

Nope. I don't change anything physically at all. I'm pretty sure it has something to do with my PC since I don't get these symptoms with my other PC. Both PCs are running windows 7 and using the PS/2 port. I'm not sure what else to be looking at.
-
With computer off plug in keyboard. Turn computer on and it should work... is it after this you are having problems?

Yep this is what i'm doing. I tried replugging my keyboard between shutdowns like you mentioned but it doesn't help. I will have to restart to get my keyboard functioning.
Btw, i've recently updated my BIOS and cleared CMOS. Both did not help out.
-
Probably not getting enough juice from the PS/2 connector.
Get a Blue Cube.
See the PS/2 Versus USB Wiki for details.
http://geekhack.org/showwiki.php?title=USB+versus+PS+2
I find it a little weird since my steelseries 7g works fine, but maybe the IBM Model Ms need a little more power.
Interesting. It might be because my PC is using a dual purpose PS/2 port (Asus P67) while my other PC that is working fine has 2 PS/2 ports specially for a keyboard and mouse.
Another thing I overlooked is that i've been using the same SDL cable. Maybe it's just faulty or not getting enough power? I'll try to find a solution when I get home in a few hours.
-
Hah, I have a Asus P8P67 Deluxe.
It works with my DealExtreme Scissor Switch on PS/2 but never bothered to plug in an IBM.
Probably ASUS never did either. That's why these "My PS/2 connection doesn't work" posts come up just about every month on Geekhack/OCN/KBDthority/HardForum. See the wiki for example links. Usually solved by a Blue Cube or Belkin.
Still the OCN Mechanical Keyboard Guide recommends PS/2 uber alles. What a Nazi editor!
Ah I see. I'll probably end up getting the blue cube anyways now. I have the P8P67 WS Revolution so we probably both have the same PS/2 port. Thanks for the help, i'm guess the blue cube will work but I kinda want to stay with PS/2 for reasons mentioned on OCN :Cry:
I found this quote on clickykeyboards that basically confirms the power issue. Online reports indicate that vintage IBM ps/2 keyboards pull up to 100x more current compared to modern keyboards (112 mA vs 1.2 mA)
-
Don't blame me if the $10 dongle doesn't work to fix this. Sometimes it DOES end up being the keyboard but I have faith in the good old Model M.
Yeah considering it's 3 Models Ms my luck would be pretty bad if it's was defective keyboards.
-
I received my model m today and I thought you should know the same thing happened to me! On first boot the board had num lock light on but nothing registered. After a reboot it fiirerd right up!
I don't have a powered ps2 to usb adapter yet :(
-
Stuff like this is almost always motherboard related. Especially when three different keyboards do it.
-
The motherboard is the p8p67 deluxe. I think I found a grerater problem though; the keys seem to be double rergistering, even at the miiniimum rerpeat rate :( See my typos?
-
Think it's a possibility of being underpowered causing the keys to double register?
-
Could well be lack of power causing the controller to behave incorrectly.
-
I'll run out to Fry's then, fingers crossed!!
-
Wellp, that's bull****. $15 later and I still have the same problem. I guess we should have buyer beware "seller refurbished" on ebay probably means it's garbage. Of course the seller can't/won't do anything.
http://geekhack.org/showthread.php?5132-Model-M-stuck-repeating-key
-
Hmm, hope there isn't a P8P67 problem with model Ms. I've identified the P8P67Pro as the finalist for my upcoming build.
-
My blue cube should arrive in the next few days and i'll test it on my P8P67 WS Revolution, P8H67-i Deluxe and P67 Sabertooth. I'm guessing if all my Asus 1155 have the same PS/2 specs, chances it's the same with the rest of the line up
What motherboard?
So you have to boot twice to use your Model M? I'm more used to seeing it not work at all. Or just work.
Someone else on hardforum mentioned the same problem too
-
My new Gigabyte mobos power the Model M fine with the ONE PS/2 they provide. These are AMD systems. I think we are seeing the power-reduction future at work here. I think as Ripster has said before, eventually, the PS/2 goes the way of the Dodo.
-
This problem sounds Asus specific. Gigabyte tends to support legacy tech longer, so I wouldn't be surprised if it had no issue running across their lineup for P67. I don't have a Model M to test this theory though.
Funny thing about my Sabertooth P67 - with my Noppoo I couldn't use the keyboard in the Windows Boot menu (Selecting normal boot, safe mode, etc) with any USB port whereas on my P67A-UD7-B3 I had no problems.
My assumption was that it was activating and locking numlock thereby swapping certiain key functionality until I got into the OS.
-
A rumour without evidence is the best kind. In fact, it's the very definition!
I hear Asus' boards kill their owners and replace them with androids as well btw.
-
Thanks for the test. I don't think its Asus vs. Gigabyte here. We need to wait for AMD's Bulldozer chips and new motherboards first. Once all CPU's get down to 32nm in core size, I wouldn't be suprised if legacy support for PS/2 goes away for good.
-
USB would be fine if the adapters didn't have translation tables built in, and actually passed along exactly what they got, just converted to a USB code. It completely sucks using a 1397000 Model M via a USB adapter, as all of the additional keys just flat don't work. At least, not when I tried with my Belkin adapters.
-
Just got my blue cube and all 3 of my Model M (SSK, 1995 Lexmark, 1991 IBM Model M)works with all 3 of my 1155 Asus boards.
-
Blue cube didn't work for my focus. :,(
I saw a thread where another guy had a focus that didn't work with a blue cube as well but some cheap one did. So I may have to get some to try out.
-
So is the consensus that it is in fact an issue with Asus SB boards?
-
That sucks. I guess the price doesn't matter when it comes to PS/2 quality. My cheapo MSI board that I got in a Athlon bundle works fine..

You may be interested in this DIY converter (http://geekhack.org/showwiki.php?title=Island:17458) going in the mod section. It can be setup to use the extra keys on terminal boards and the like.
-
My experience with PS/2 originates from my Model M '88 and my GBT 770TA-UD3 - no problems until the SDL cable decided to brake just a little before the SDL-connector; so no more click. Only the sound of BlackMX.
-
Seems to me it is not the PS/2's fault modern motherboard designers ignore the correct specs. When plugged into my Lenovo Thinkpad Docking Bay's PS/2 port, IBM M keyboards work exactly as designed - no adapters needed.
Perhaps IBM/Lenovo remembered to allow sufficent power at the port for all keyboards - new and old - to work. That makes the motherboards you guys want to use the actual problem. What other detail did the designers miss? An industry standard port should work, period.
And when they quit shipping junk keyboards with new computers, then I'll feel better about USB keyboards. Cheaper ain't better. Thinkpad Fan
-
Yeah, this annoys me. Right now I've identified the P8P67 Pro as my SB motherboard when I get around to doing a build. I guess I won't be using my model M, or who knows how many other PS2 mobos won't work.
Sure, I can "buy a thing to do that", but that's already true of a laundry list of things most motherboards don't seem to do correctly. Soon you're doubling the cost (and power profile) of your motherboard buying add-ons to do things that the onboard components should do properly in the first place.
-
If an M doesn't work, I would have written off the even more power-hungry F right away. But the M4...
Mind bugging the Asus folks? There is a slim but greater-than-zero chance of it not being a hardware issue.
-
Obviously not using the trackpoint - see my pic above.
PS/2 Y splitter?
-
ASUS mess things up occasionally.
-
ASUS mess things almost always.
ASrock (which ironically is an ASUS subcompany) rarely makes mistakes.
BTW ripster do you ever noticed the nice BIOS menu PS2 port function = AUTO / Mouse / Keyboard ?
Maybe Auto V.S. keyboard makes the difference.
-
Nope. UEFI settings don't make a difference.
Ahhh it's an UEFI board !!!
This could explain a lot.
I've not much experience here, all the UEFI PCs I tried were notebook, or legacyless MB, so no PS/2 ports to experiment with.
-
It doesn't explain anything.
UEFI is just too young, that's all
Likely on the Bios version 1840258832 you will get your port working correctly.
For now I'm glad to use an Asrock 870 Extreme3 (which is BIOS based) instead of the Asrock 870 Extreme3 R2 (which is UEFI based).
You still think Obama was born in Indonesia?
At lest i don't think that Bell invented the phone :becky:
-
This is an unexact science, the variables are zillions.
Just for example, some MB have the jumper to choose if the back USB ports should be always powered or just when the PC is on.
Frequently that jumper swaps also the PS/2 5V line.
So could be interesting to know if your PS2 connector is always powered or not, if changes its beaviour moving the USB jumper, and finally if this helps with the OP problem
-
Jumpers? I don't have no STEEENKING Jumpers. I'm American so I buy modern motherboards.
And modern cars... :tongue:
Seriously intel still sells mainboards ?
And there's someone that buy them? :shocked:
On a Intel Badaxe2 Motherboard (circa 2007)
Cold Boot
Works in the bios
Doesn't work in Windows 7 32bit
Reboot
Works in both bios and Windows
Immediate Shutdown and Reboot (hey, maybe it's a charging up the caps issue!)
Works in bios, not Windows
Stupid Intel
On my nifty 2011 Rev 3 ASUS P8P67 Deluxe (aka the fixed Intel Sandy Bridge)
Cold Boot

Doesn't work in Windows 7 64bit
Reboot

Immediate Shutdown and Reboot

Stupid Asus
If the keyboard works in bios but not in windows (this was not clear in the previous messages) likely is just a windows problem.
Try what happen with a live linux distro, if it works always, likely an in place upgrade of windows with the keyboard connected to the ps/2 port during the installation process will fix the problem.
-
In other news my ASSrocks Quad 6700 motherboard PS/2 port works fine with the Bernie Madoff Mini.
You got a good mainboard, you got less troubles. As always happen.
It has a normal BIOS, not a UEFI. UEFI is better.
Likely UEFI *will* be better in the next two years, as always happened to any new IT technology.

Well...
Was a 50% joke 50% technical consideration, really the MB division is not the best Intel's one. (I really hope you aren't the division manager :) )
-
This year, maybe as a present for my birthday, I'd like just one geekhack thread to stay on topic... Generally "stay on topic" Nazis annoy me, but I think we need a couple around here.
-
I saw on [H] yesterday that when someone started overclocking their Model M started working. Not sure if they participate here too.

As to why PS/2 keyboard won't work with a certain motherboard, there could be two reasons:
1) insufficient power
2) protocol violations - bad timings, signal integrity problems, etc.
Once a dedicated MCU, the motherboard PS/2 controller is nowadays buried in the Southbridge (if present at all) as a macrocell. So it varies wildly in implementation, and with the small firmware it includes, that's another possible source of problems.
Ripster, why don't you try further correlating the PS/2 problem with the Southbridge chip used? Like, two different motherboards using the same Southbridge chip (PS/2 controller)? Perhaps GHers could lend a hand.
-
Not just Intel, but the same particular chip number, like 82801GB or whatever.
-
Do a lazy experiment - get a PS/2 Y splitter. Measure the 5V rail, then attach keyboard and measure again.

Then mutilate the right wire. Or the left.
-
Lol - I AM OCing (a very mild OC with no voltage bump)! Maybe if I bring my 5V Rail to 6V!!!!! On a PC Power & Cooling Silencer 750W so I KNOW it's not the power supply's fault. My Intel BadAxe2 also has a mild OC.
I didn't say I could explain it, or that it made any sense :)
-
4.87V is ok, 2V is not.

This old link might shed some light on the subject. This problem has been around for awhile.

QUOTE: When I recently upgraded my motherboard to a new ASUS P4T-E, I was disappointed to find that this motherboard was unable to detect my old keyboard. So after using a $10 plastic keyboard for a few weeks (and cursing it numerous times), I decided to investigate the IBM keyboard compatibility issue.

Even from a NewEgg review...
Customer Reviews of the ASUS P8H67-I DELUXE (REV 3.0)
Cons: PS/2 port does not work in many instances. It would not work with 3 of my IBM Model M keyboards (They are all over 15 year old keyboard). I did not take off any eggs because this is a known issue with many modern motherboards, but I just wish Asus support the old IBM PS/2 specs. Fixed this issue with a blue cube (Convertor).
Hey Ripster...did the Blue Cube allow some of those to work on your Asus P67 board?
Also, another massive old link from IBM....
http://www.burtonsys.com/ps2_chapweske.htm
-
I guess I better order a Blue Cube pronto. I'll upgrade to Sandy Bridge (or Bulldozer if its any good) soon.
-
This was interesting as well. For the record all my testing was with the shortest coiled SDL cable I have.
I have tested with the long and short cable on my small collection of Model Ms (Three). Didn't make a difference. Didn't work but with the blue cube it does work.

That was my review :wave: and the blue cube has fixed all my Model Ms on all 3 of my Asus 1155 boards
-
So I've made the switch to Sandy Bridge. My only PS2 model M is at the office though. If I ever bring the two together I'll post and update here.
Ripster: I see that you saw the user on [H] report that an OC reliably makes his M work every time. Weird.
As an aside, I got the P8P67 Pro and I could have sworn that the materials I saw prior to buying showed a single purple/green combined PS2 just like Ripster showed in one of his posts. Mine has two PS2s - mouse and key. Maybe only the Deluxe has a shared one and multiple places screwed up their pictures?
-
I'm beginning to swing to the clock timing theory since this shouldn't affect power draw should it?
Signal integrity problem. Power draw change by 4.7K pullups can be safely ignored.
-
Little bit of info on this issue from an Asus rep.
http://hardforum.com/showpost.php?p=1037229338&postcount=2453
-
I doubt the problems are related but we'll see.
After all, I don't know what's going on in my Intel BadAxe2 but acts the same and its from 2077 when people still did BIOS instead of UEFI.
Well, it's better that an insider is looking at it than having the attention from Asus limited to filing a ticket with a front line service rep, right?
Now that I'm running my P8P67 Pro I suppose I should test every PS2 board I have in the house... Unfortunately my Model M is at the office.
-
I guess what's happing is that the controller's logical "high" level may be a touch on the low side to begin with, and if PS/2 supply drops too much under load, it goes down too far for reliable communication. The pull-up resistors help correct that. Sure, it's a kludge, but if it works...
-

I still have high doubt that the power supply is the problem. Likely is just a signal treatment problem, and the pullup resistors will help to fix it.
-
The other thing I was thinking of testing was to inject a regulated 5V through a dedicated power supply, bypassing the motherboard.
You don't need an external power supply to do this test.
Just use the untouched 5V from the PC itself, the easier way is to use a a molex to sata adaptor, which is usually bundled with most MB and connect a wire to the RED cable.
-
I've heard of SATA.
Think just that this is not an MP exchange a lot of people read and a part of the readers are newbie, so when there's the risk of burning something if the wrong cable is used is better to repeat even basic concept like the HDD power connector wiring.
-
I love to be pedantic with pedantic people...:bump2:
-
Well, like most of your input you are certainly adding little value to this thread.
I already said how to proceed, you just skipped my suggestions.
So don't blame me.
-
Exactly. I'm still not so sure that this will fix the problem.
But anyway is worth to try, if it works you have the solution. If it doesn't you have surely power drains from the possible causes of the problem which is still a good step in the right direction.

My new desktop, Asus 8PH67 EVO, Sandy Bridge with a single green/purple PS/2 port (or maybe it's purple/green, I don't remember which is the PS and which is the 2 and I'm not looking to find out now), gave me strange behavior with my M15.
I got through at least one reload of the box (it arrived blank), maybe two, with no keyboard trouble, but at some point I noticed the keyboard wasn't working, and thus began a stretch of flakiness. I noticed it would work in BIOS, but once Windows booted (Server 2008 R2 SP1), no keyboard functionality and no LED *Lock action. Damned annoying, especially since I didn't have a USB keyboard handy. (I have a blue cube in a box but I've never needed it so I never thought of it.) I'd hit the reset button and maybe the keyboard would work.
But it seems fixed now. The fix? I bought a USB mini keyboard at the local geek store. It hasn't left its original packaging yet -- the M15 hasn't acted up since the USB keyboard arrived. Insufficient sample size, but so far it's working.
Actually, now that I think about it, it could be that it was flaky with the Lexmark but not the IBM Options (Jul-94 split cord, Dec-94 daisy chain cord respectively), because at some point I switched them. I should probably switch them back, because the Lexmark feels tired. Actually, I should probably dig up that switchbox that works with ThinkPads. (The numpad was never connected, btw.)
Sigh. I wish I had been more scientific, but it was a long week of multiple failures -- FedEx failed to deliver my new desktop, then as soon as I got my desktop my ThinkPad died, my desktop was grooving to the BSOD extended dance mix (Duran Duran would label it the "Night Version"), my car battery died, and my other car got a blowout.
Maybe I'll go back and run through my paltry PS/2 keyboard collection in more controlled fashion. Really, I do know how to do that, generally; it was just a really bad week.
-
Thanks to you I had that song in my head all day.
And it was not like this (http://www.youtube.com/watch?v=wa2nLEhUcZ0) at all.

Didn't read the whole thread since as usual it's full of off-topic pointless pictures, bickering and other nonsense, so I may have missed something of actual worth. That said a couple of points:
1) Asrock is the same company as Asus, used to be their budget division, so it's no surprise they both behave the same way.
2) From my own experience, with an Intel DP43TF motherboard, a 1391401 Model M will not function properly if Numlock is turned on in the BIOS, but it works fine if it is turned of. So in that case it's clearly a power issue, presumably the extra current drawn by the Numlock LED. Since Windows remembers Numlock setting per account, it can be turned on there and will then come on automatically upon logon.
-

Asrock is a completely independent company from the technical point of view.
Usually there isn't a single point of commonality between the two MB of the same class, firmware included (often AWARD in one and AMI in the other)
I must add thanks God, given that usually Asrock boards are almost always problem free, while ASUS ones are used to have all kind of problems, especially with the first releases of bios.

Since Windows remembers Numlock setting per account, it can be turned on there and will then come on automatically upon logon.
Alli is possible, but I still think that is not a power issue and that 5 mA of power drained by a LED couldn't make any differences.
-
Update: I've tried each of my PS/2 keyboards once, and I did not have a single failure with my Asus 8PH67.
I connected each keyboard to the system, which had been off for at least a minute. I powered on, observed the LEDs (if equipped) flash; upon seeing the main BIOS POST, I hit CapsLock twice and confirmed the LED worked. After Windows gave me the Ctrl-Alt-Del prompt, I hit Ctrl-Alt-Del, logged on, then initiated Windows Shutdown.
I tested keyboards in this order:
SIIG MiniTouch
HP SK-2880 (PS/2 keyboard bundled with an HP dc7800 circa 2008)
Fujitsu FKB-4700
IBM PS/2 Space Saving Keyboard
M15 IBM Options
M15 Lexmark
Tested after 2am on a cool night with light rain. The window was open, and I'd just come back from seeing X-Men: First Class. I had a non-winning Mega Millions ticket on the desk, and I was feeling a little gassy.

so are these the required conditions for success?
-
No idea. I was surprised at the lack of failure, considering the grief it was giving me for a while earlier.
The M15 worked fine again just now after being off overnight. *shrug*

Part No.: 1395100
Model: M
Manufactured by Lexmark
There's a sticker underneath that one but I can't read it. No serial number so I don't know its vintage, though it's a blue-on-dark-beige logo if that helps. IIRC I bought it almost-new-in-box from clickykeyboards just before prices went nuts a couple of years ago.
I just tried it again and it worked again. Ctrl-Alt-Del password logon Ctrl-Esc right-right Shut down Tab Tab reason Enter, so yeah it really works. (It feels marvelous! A bit heavier than the M15s. No, I don't have enough nickels here.) Maybe I got lucky and my board's components happen to keep it within spec, or maybe the H67 chipset differs from the P67 in its PS/2 support, though that seems unlikely given their fraternal nature.
I'd borrow my coworker's full-size 1990s M but it's his all-day board and I fear the subatomic toasticles.
-
You really should try reading threads sometime.
I've tried, but when 2/3 of the posts in any given thread are pointless pictures and other nonsense from YOU, I find it a huge waste of time to try to find the actual useful information. So maybe I'd have seen the info about Asus vs. Asrock if it wasn't buried in a heap of Lego pics and other crap.
-
The mini-M didn't work on power-up two nights ago. Twice. Worked the third time. (It's been powered-on since.) So I'd call the PS/2 port on the Asus 8PH67 (EVO) potentially troublesome, at least.
-
My Datahand Pro II with PS/2 attached with a y-splitter PS/2 cable to the ASUS Z68 Deluxe did not talk to UEFI.
-
However, the Fujitsu D3076 motherboard (Intel Q67, that is LGA1155) comes with two PS/2 ports that work with my Compaq 11800.
Hurrah for German engineering! (Fujitsu used be Fujitsu-Siemens).

Hi everyone!
i just got a quite rare Ibm Model M with italian layout (10$ from eBay). and i'm experiencing som issues...
well, not that wierd actually, let's say i'm just not able to make it work with my computer at work.
At home i've just Apple Computers, while at work i've more than one Pcs..the thing is that the keyboqard seems to work perfectly with a self assembled computer, with an Asrock mobo, while it's not working at all with a Lenovo Thinkcentre m55, with intel mobo...
when i plug the keyboard, the computer boots automatically, and the keybord lights up correctly, but as soon as i press a key...booom, the computer freezes and i can't do anything but restart...
any help or suggestion?
-
Try going USB at work -- use a PS/2-keyboard-to-USB adapter, one designed specifically for keyboards (not the ubiquitous generic mouse/keyboard adapters) like the "blue cube" adapter.
-
Thanks for reporting this. Added to the PS/2 compatibility wiki. My Asrock is pretty well behaved too.
i made a mistake reporting the model of the Lenovo computer at work, it's an M55e not M55p ;)
the M55p has no ps/2 port for what i remember!
-
I justread (in Intel documentation) that PS/2 ports are implemented in the Super I/O chip -- this is not part of the processor chipset, but connected to it via the Low Pin Count bus (LPC, which kind of emulates the ISA bus).
So PS/2 support (or lack of it) is a motherboard or Super I/O issue, not a processor chipset issue.
-
UEFI FTW!!!
Not to be picky but looks like UEFI atm has ****ed just you...
-
Oh here we go again.
Italian logic random conjecture without realizing that a lot of non-UEFI motherboards also share the PS/2 compatibility problem.
Ping!
My keyboards and my pcs are all correctly working, your doesn't. This is my "Italian logic"
Your (I hope not shared) American logic is still insisting with random test w/o following a basic chain of tests I suggested an era ago.
-
lol, i'm italian too!

Me too.
Ripster is racist against Italians.

No wonder nobody wants to read this thread. "Not to be picky" then don't post ffs.
How will UEFI eliminate the PS/2 port?
-
Yeah, did that; UEFI is mentioned once in passing, in the same sentence as the fading of PS/2, but it's a vaguely-worded sentence, perhaps on purpose. Does UEFI dictate the elimination of PS/2? It seems not, inasmuch as at least one motherboard producer has products with both UEFI and PS/2 together. Does UEFI speed PS/2's demise any more than the general pressure to drop anything from the fab that doesn't help sell it? Is there a direct technical cause-and-effect I'm missing? Inquiring minds want to know.
