Note
You can find listings for additional POST checkpoint codes at www.postcodemaster.com .
Also, see Chapter 5 , “ BIOS , ” to learn more about working with your BIOS. Remember to
consult your motherboard documentation for codes specific to your BIOS version.
BIOS POST Onscreen Messages
Onscreen messages are brief messages that attempt to indicate a specific failure. These messages can
be displayed only after the point at which the video adapter card and display have been initialized.
These different types of error messages are BIOS dependent and vary among BIOS manufacturers,
and even in some cases among different BIOSs from the same manufacturer. The following sections
list the codes used by the most popular ROM BIOS versions (AMI, Award, Phoenix, and IBM BIOS),
but you should consult your motherboard or ROM BIOS manufacturer for the codes specific to your
board and BIOS.
Most POST code cards come with documentation listing the POST checkpoint codes for various
BIOS versions. If your BIOS is different from what I have listed here, consult the documentation for
your BIOS or the information that came with your particular POST card.
