Tekram K7KX-A PS/2 keyboard will not work. Get Adapter
I powered off my system to swap hard drives.
When I restarted the system BIOS and the OS on the swapped drive had
compatibility issues. My next step was to power down again, remove the
battery and clear CMOS.
After reinstalling the battery and placing the CMOS jumper back to
'normal' when I powered up again the system would not detect my PS2
keyboard. DEL and F1 had no effect. Swapped out keyboard - no help.
Final solution: Get a USB-to-PS/2 Adapter. This allows the PS/2
keyboard and mouse to connect through a USB port. Belkin Part #

The only thing I can suggest in this scenario, is to go through your BIOS again, and check for options to enable/disable your PS2 ports, and that's the best-case outcome.
worst case outcome is that when you were swapping your hard drives, an improper circuit was made, and static (ESD) killed a component on your motherboard. Did you use a grounding strap, or ground yourself when you had the case open? another thing to check for, is if the wires connecting the ports are whole, and not bent or loose.
if this doesn't help, i'd definatly go with the USB adapter, to see if that works. if not, there is a possibility you might have to buy a new motherboard, in itself.

This answer relates to keyboard hardware issue only.
On powering on PC look for keyboard lights flashing.
If no flash. Power down. Remove/replace kbd plug.
If still no flash of lights then please read on.
If kbd is old ps/2 type. Which is small round, sometimes purple, plug.
Ensure its not in not in the similar mouse socket.
Check for bent pin in plug.
ps/2 sockets can fail (as can keyboards)
If no joy and no other ps/2 keyboard works, consider replacing with usb type.
If kbd is usb type, do power off/on look for lights flashing.
If no flash of lights, try in different usb port.
Try replacing keyboard.
are you using a usb keyboard? A lot of systems require a ps/2 (purple round connector) keyboard to access the bios settings and anything on the startup screen unless you have set usb on boot in the bios settings. I would try connecting a ps/2 keyboard and see if it helps.
Unfortunately BIOS reset will not help you, the default setting for USB keyboard support is set to OS and you need set it to BIOS. I would recommend you to go with your mainboard to a specialized service, sometimes the problem is only a defective capacitor. If you reset your CMOS, the first boot device will be set to Floppy. You could try updating your BIOS to the latest version (maybe in that version the USB keyboard is set to BIOS) but I don't know if you can create a batch file to update the BIOS automatically, without confirmation from keyboard... The reliable solution is the technician. You can also try to connect your PS2 keyboard to the mainboard using an USB adapter but as I know in that case the keyboard is treated as an USB device...
If this is the solution for your problem, please rate my post, otherwise give us more details.
It seems it is a product of SiS. Visit http://www.sis.com.tw and search the BIOS upgrade in the download or support section. If SIS has launched any upgrade for your product, it will be available there. (email@example.com)
what is the connection type of your keyboard? is it PS/2 or USB?
well, if your keyboard is a PS/2 type, there might be a problem with the PS/2 keyboard port, because you've said that it works well with your other PC.
if your using a USB type of keyboard, well try to check if your SYSTEM BIOS supports USB Keyboards. because there are some PC doesnt supports USB keyboard on its BIOS. if it supports, well, enable the USB Devices on your BIOS settings to ON.
If the BIOS it self is not opening means that it is not getting started,at the timing of power startup it just goes off with out showing anything the issue might be with the BIOS cell check that out otherwise there might be any issue with the BIOS than u have to consult with the vendor,
Now in second case where it is not working after the POST is done than might be the first boot sector has gone faulty you have to reinstall the OS.
ANd in if case it is giving a long beep before shutting down the issue might be with RAM check that out.
Inshort the issue might be with three things
1) BIOS cell (change the bios cell)
2) BIOS itself (consult vendor)
3) OS (Reinstall the OS)
4) RAM (Swap or change the RAM)
PLz do rate incase this info is important or giving u any benifit it helps us...
Apparently there is something confilcting with something ot the ps2 ports are faulty!
We'll need to find out!
Try plugging up your system without the video card but the ps/2 devices plugged in! (we don't need to plug up hard drive, so plug them out if they are plugged in)
When the system comes on(after your hear the POST beep, if the system speakers is plugged up to the motherboard). Try pressing NUM LOCK or CAPS LOCk to see if the light come on and off. If they do that means your machine is responding with the PS/2, if not then you need to find a PS/2 expansion adapter ot use a USB Keyboard and mouse!
If you do get a response that means your ports are working and there is probably a confilct with your Video card!
In that case, I assume you've already reset the cmos(if you haven't then do that).
Also if you have an AGP port try an AGP Card, if you were using an AGP card try a PCI!
Well the USB keyboard more than likely will work!
try these out and get back to me!
