Changeset 105 for trunk/bootcode/regular/other.asm

Message:

Moved the INT13X DAP to the BSS [v1.1.1-testing]

No need to have this in the image, eating up precious code-space.
The byte holding the packet size is now initialized from PRERAP.

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:
