Sometime on Feb 28, Kunal Gangakhedkar assembled some asciibets to say:
Your OS is supposed to communicate with BIOS for any device queries. So if your BIOS itself is not reporting beyond 8GB, how can any OS detect more than that??
nope, not true. the os can query the bios for the disk geometry, or it could get it from the disk controller directly. the hardware can be queried directly. the only purpose of the bios really is to load the os.
