I pasted the patch commentary as weel as the patch.
These changes were necessary in order to allow LinuxBIOS to
install windows from an installation CD. Windows seems
to require that the BIOS used during installation be the
same used to run it after installed.
- In the file loader.s I commented out the CMOS settings
that force booting from Hard Disk.
- In the rombios.c the functions responsible for booting
from CD-ROM are turned on.
These changes are only necessary to install windows, after
installed they are no longer needed.
