POST Diagnostics
Power On Self Test (POST) Errors
Whenever a recoverable error occurs during POST, the BIOS displays an error
message describing the problem.
If a system boot is incomplete (for example, the system is turned off while it is
going through the POST), then the next time the system is powered on you may
get a message stating that the previous boot was incomplete. The BIOS will
revert to “safe” values for the chip set, caches, I/O components, etc. This will
provide the best possibility of getting back to Setup. This automatic return to
“safe” values provides the best possibility of returning to normal functioning,
but these values do not always produce maximum system performance. To
achieve maximum performance after the BIOS has reverted to “safe” values,
re-enter Setup and select maximum performance values.
If, for example, the terminal was simply turned off during POST, the user can
return to the maximum performance values by simply entering Setup and
exiting, or by booting and then rebooting.
During POST, the user will be asked to press <F1> and boot with the default
configuration. If the user simply presses <F1> and does not later return to Setup,
the system will boot; but the external cache will not be enabled, even though the
default configuration will enable the cache.
