This is your APM BIOS attempting to use a real mode segment while in
protected mode. i.e. it is a bug in your BIOS. Complain to HP.
We have seen a few of these recently, except all the others are in
the power off code in the BIOS wher we can work around it by returning
to real mode before attempting to power off. Here we cannot do this.

This is the selector for the APM BIOS 16 bit code segment.

Yeah, this is where the kernel does the call back into the BIOS code.

Different BIOS version.
