So I'm trying to bring this 486 board back from the dead.. I now have video, and can boot! yay
But im getting an error when I boot. CMOS battery was bad when I got this, so I've replace. Getting some bios Errors, and it also states
"Keyboard error"
And wants me to either f1 to continue or Del for setup.. Keyboard is totally unresponsive.
On boot the keyboard lights flash bright, but then go dim. All lights are on keyboard, just dim tho..
This motherboard also has a keyboard lock. Currently its on a test bench, nor do I have the original lock / keys
I believe I have successfully shorted the right pins, as if it short again, I get 2 errors...
Keyboard Error..
And keyboard locked.,..
After shorting, I just get keyboard error.
Any ideas?
EDIT: Some trouble shooting I've done.
1>. Unseated and reseated the keyboard bios chip
2> tested continuity between the keyboard clk and keyboard data pin. tested fine.
More things I've tried:
Removed Keyboard Bios All together. Did not post.
Used a keyboard Bios from a known good 386 board. - Still gave keyboard error, but would hang, normally I would get the keyboard error, and then it would try to load the floppy drive etc, but with the other bios it would not get any farther except for the Hit DEL for setup
Rechecked Traces. Everything looks good. Multimeter shows continuity. The battery had leaked prior to me getting this board, but cleans up nicely, and I can't find any damaged traces.
