Error Message Summary
Error Message Summary
The Error Message Utility or EMU (.COM application written in C language) is to provide
full screen online help messages (localized) on most common POST errors. When an error
is generated in POST during the boot process, EMU is run by typing
ENTER
. The entry
point of each EMU message is a 4-digits error code generated by POST.
If the POST reports an error, one of the following four error categories will be displayed.
Category #1:
if the error requires Setup to be run, the POST should prompt:
<F1= Continue>, <F2= Setup>, <Enter= View System Error>
and pause. (Refer to autoconfig specification for more details on POST prompts)
Category #2:
if the error is only a warning (i.e. key stuck), the POST should prompt:
<Enter= View System Error>
for 2 seconds then boot. (Refer to autoconfig specification for more details on POST
prompts)
Category #3:
if the error occurs because a device has been unplugged or removed, the
POST should prompt :
“If errors are reported because one or more of the listed components have been removed,
press <F4> to validate the changes.”
<F1= Continue>, <F2= Setup>, <F4= Validate Change>, <Enter= View System Error>
and pause. (Refer to autoconfig specification for more details on POST prompts)
Category #4:
if the error is serious, the POST should prompt:
The BIOS has detected a serious problem that prevents your Personal Workstation
from booting.”
<F2= Setup>, <Enter= View System Error>
and stop. Only the setup and the EMU can be run. The BIOS must never boot on
HDD.
