I think this is the very same thing as for El Torito: El Torito is based
on lba able BIOSes and builds an CHS emulation on that. Here this is the
very same thing I guess: to obtain the BIOS id of the device you need LBA,
but you need to access after that with CHS. I think that without the
force LBA flag, only the traditionnal/old int13 related to CHS was used
and the device was not accessible this way.
This is just a guess.
