Code 8 are fatal. If POST initializes the system video monitor, errors
can be displayed on the screen. Displayed errors (see page 37) allow the
system to continue.

Troubleshooting System Problems
What to Do If the Computer Beeps
If the system beeps...
then...
1, 2, or 3 times...
reseat the memory SIMMs or DIPs. If the system still
beeps, replace the memory.
6 times...
reseat the keyboard controller. If it still beeps, replace
the keyboard controller. If it still beeps, try a different
keyboard, or replace the keyboard fuse.
8 times...
memory error on the video adapter. Replace the video
adapter, or the RAM on the video adapter.
9 times...
the BIOS chip is bad. The system probably needs a
new BIOS ROM chip.
11 times...
reseat the cache memory on the motherboard. If it still
beeps, replace the cache memory.
4, 5, 7, or 10 times...
the motherboard must be replaced.
