Advanced error reporting
All errors are reported on the POST screen at the end of POST, before booting the OS. If there are any
Fatal on unrecoverable Non fatal errors reported, you will be presented an F1 Boot prompt. This ensures
that the system doesn't boot before you have a chance to see the errors. The errors displayed are from
the previous boot. They occurred before the most recent reboot, or they caused the most recent reboot.
Error reporting control
There are several ways to control the allowable errors and their results. For each error, there are three
actions that can be performed:
●
Mask and ignore the error
●
Log the error in an error status register but don't generate an Err0 signal
●
Log the error in an error status register and generate an Err0 signal
There are two types of non-fatal errors—correctable and uncorrectable. The type of non-fatal error
determines how the error is handled.
Correctable
Correctable non-fatal errors are masked so they are logged, but they will not generate an Err0. These
errors will only be reported if you have selected to force an F1 Boot prompt on recoverable errors. This
option is available under Advanced > Power-On Options. The default is to not force an F1 prompt.
Uncorrectable
uncorrectable non-fatal errors are masked so they are logged, but will not generate an Err0. Unlike
correctable non-fatal errors, the uncorrectable non-fatal errors will automatically force an F1 Boot prompt
on the next reboot.
Fatal errors are not masked.
When errors are detected and not masked, they generate an Err0 signal. There are four ways to handle
this type of error.
●
Ignore (mask out the error)
●
Generate an SMI which results in a reboot
●
Generate an NMI which results in a crash
●
Generate a Machine Check which results in a crash
Default is to generate an SMI. Use the Advanced > Chipset option in the F10 Setup menu to control
this type of error.
