Message:

Optimized reading a sector from disk using INT13X [v1.1.1-testing]

At this level it is more clear to talk about 'reading' and 'writing'
sectors, where 'disk read' and 'disk write' errors can occur.

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:
