Table 2-1
Message
Description
Recommended Action
Hard disk controller error
The hard drive controller failed
to respond to the reset
command.
Check the drive parameters. Turn off
the system and check all related
connections.
Keyboard controller failure
The keyboard failed the self-
test command.
Replace the system board.
Keyboard failure
The keyboard failed to respond
to the RESET ID command.
Replace the keyboard. If the problem
persists, replace the system board.
No interrupts from Timer 0
The periodic timer interrupt is
not occurring.
Replace the system board.
ROM at xxxx (LENGTH yyyy) with
nonzero checksum (zz)
An illegal adapter ROM was
located at the specified
address.
Check the external adapter (such as a
video card) to determine if it is
causing the conflict.
Time/Date corrupt - run SCU
The time and date stored in
the real time clock have been
corrupted, possibly by a power
loss.
1. Run Computer Setup.
2. If problems persists, replace
system board.
Hard disk xx failure (or error)
A failure or an error occurred
when trying to access the hard
drive.
1. Run ScanDisk.
2. Check disk in DOS and
Windows 95.
Fatal errors emit a beep and may display a FATAL message. Fatal errors indicate severe
problems, such as a hardware failure. Fatal errors do not allow the system to resume.
Some of the Fatal error beep codes are listed at the end of this section.
