Keyboard Stuck Error on Bootup
Hi,
I have an HP 2978A system with 1ghz Athlon running Windows 2000 Professional that exhibits the following behavior:
Upon boot "keyboard stuck error" message generated from BIOS
Machine boots okay to Windows 2000 and works fine
Machine boots okay to Windows 2000 and no keyboard and beeps periodically
I've tried several known good keyboards on the system, PS/2 interface, and the machine exhibits same behavior.
What's the cure?
Thanks,
Ron

I assume then the only way to fix PS2 port then is to replace the mainboard?
Would any setting in the BIOS affect this? The BIOS has not been changed to my knowledge and has been working fine up until now.

Yes, I agree with Thane, it sounds like that more than likely your PS/2 port on your motherboard has gone bad, look into using a USB keyboard, and be sure to enable the USB Keyboard in CMOS. It should work, else replace the mainboard.
Try disconnecting the mouse before you give up on the MB. Sometimes a bad mouse can mess up the PS/2 port enough to affect the KB input (e.g. taking too much current from the port).

Hi,
The mouse & keyboard are color coded and plugged into the correct PS/2 ports. I tried unplugging the PS/2 Mouse and that did not affect anything. The exact error message now is:
0210: Stuck Key FF
The machine beeps wildly.

Suggestions only
Open up box and see if there is a jumper to reset BIOS. Or remove battery for half an hour and reinstall and reboot.
Open box and press down on BIOS chip to make sure it is in properly.

Suggestions there indicate trying to replace the CMOS battery (I wouldn't expect it to have failed already on such a new system, but you never know).
Did you "hot plug" the keyboard/mouse, i.e. while the system was on? That can damage the device itself or the port since this is a low level current flowing through the PS/2 port.

I tried pulling battery out for a half an hour and rebooting already.
The battery does hold the CMOS settings so I don't think the battery is weak.
Looks like live with USB keyboard, if I can get back into CMOS to reset, which so far I can't, and/or replace mainboard.
