POST Error Message

I was installing some graphics software on a Compaq Presario 5716 computer
that I have. This is software that I was running on another computer with
Windows XP Pro. The 5716 is running Windows XP Home and has a 850 Mhz
processer. Upon starting it the next day and going throught the POST phase
a "301 Keyboard error" message appeared. The computer completed the boot
phase and I was in the Windows desktop when I found that the mouse was
frozen and the keyboard would not respond. This happened each time I
rebooted. I was unable to go to Safe Mode because the keyboard would not
respond. I hooked up two more keyboards, all with the same results. I then
unplugged the mouse and keyboard and booted. During the POST phase I
received a "304 Keyboard or System Unit Failure" message. They problem is,
without the keyboard or mouse, I can not access Safe Mode or use any
diagnostic software. Even that which run in DOS mode. I was unable to boot
up to the last known good restore point. I was also unable to run the
Windows XP installation Disk and do a repair or full install for these
functions rely on the mouse to keyboard to execute commands. The only thing
I was able to find out about the 304 message was that is refers to CMOS RAM
configuration not matching. There was no preexisting indication of any
memory problems or graphics card problems. Is my BIOS bad? I had removed
the battery and placed a new one in with no change. I appreaciate any help
that any can offer.

Thanks,
Bill

Bill, have you tried clearing CMOS via JP1 on the systemboard (close to the
round, flat CMOS battery)?

HH,
Thanks for your help. I saw your post, went down to the basement and
pulled off the chasis cover to the 5716 computer. I found the JP1 pin with
no problem, moving the jumper from 1-2 to 2-3 and then back again. I booted
up the computer and to my jubilation, it did not show any error messages and
everything was working fine.

Again thanks for your help,
Bill
