Hi,

I have a question about protective MBR. Thanks a lot for your time.
Why is the StartingCHS of protective MBR partition record set to 0x000100 in 
RedHat / Ubuntu? While UEFI spec defines it as 0x000200.

Problem Statement:
I met a problem when trying to use FatPei to fetch a file on the GPT partition 
of RedHat/Ubuntu in TCB.
FatPei has a check about Partition Record of protective MBR: StartingCHS should 
to 0x000200.
But I find the StartingCHS in both RedHat and Ubuntu is 0x000100, so that the 
check fails.

According to UEFI spec, StartingCHS should be 0x000200.
