[BC] Computer problem

[RichardBJohnson at comcast.net]

The fact that it makes an error is GOOD! It means that the
keyboard is enabled.

If this happened when you plugged in a PS2 style keyboard,
you probably have a blown keyboard fuse on the motherboard.

These fuses look like resistors and there should be a single
"resistor like" component very near the PS2 connector. You can
temporarily jumper it with a tiny-clip to verify the keyboard now
works (do this ONLY with a known good keyboard). Once the
fix is verified, substitute a two-inch length of #60 copper wire
as a substitute fuse.  Let it stick up into the air. This will blow
at about 5 amps, protecting the PWB traces, which was the
purpose of the original fuse.

In the event that the keyboard fuse is okay (you can measure
it with an ohmmeter), then it might be that the CMOS settings
are so screwed up it doesn't know how to access the keyboard.

Not to worry. Download the motherboard instruction manual
and find how to reset the CMOS to its "boot-anything" mode.
If you can't find one, just remove the motherboard battery
for about 1/2 hour --if it is removable. You can reduce the
time, by shorting out the battery clip once the battery has
been removed. If you can't remove the battery, short it out
for about 5 seconds --yes, it will affect the life of the battery,
but it is very high impedance and won't blow up or even get
warm.
