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:
<F1= Continue>, <F2= Setup>, <Enter= View System Error>
and pause. (Refer to autoconfig specification for more details on POST prompts)
Category #2:
<Enter= View System Error>
for 2 seconds then boot. (Refer to autoconfig specification for more details on POST
prompts)
Category #3:
"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:
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
