Changeset 96 for trunk/bootcode/setup/main.asm

Message:

Removed Linux noise [v1.1.1-testing]

This stuff was already commented out and not applicable anymore.
It was used to directly boot Linux kernels from FAT some eons ago.
Linux is supported by chain-loading GRUB.

CAUTION:
This is a testbuild !
AirBoot uses the BIOS to access disks and a small coding error can trash
partition tables or other vital disk structures. You are advised to make
backups of TRACK0 and EBRs before using this testbuild. More info at:
