Hi, does anybody remember in which situations the MBR
or whatever else calls the FreeDOS boot sector fails
to pass the drive number in DL? Because at the moment,
FreeDOS defaults to ignoring DL and using the value
in the boot sector, unless that value is 255. I hear
that only some CDROM boot BIOS
Hi again,
news about boot sector properties:
- our FAT32 boot sectors always trust DL, so the code in SYS
which says "if A:/B: set 0, else set 0xff" should be changed
to "if A:/B: set 0, else set 0x80" to make the boot sector
look nicer to disk tools, right? And makebootfat and my tool
s
I can comment oly on one item:
