I would make a:
sda1 EXT3 partition /boot
sda2 FAT12
FAT12 (type 0x01) only works if you want your DOS partition to be very small,
~16M or less. FAT16 (0x04) works from 16M to 32M. FAT16B (0x06) goes from 32M
to 2G. FAT32 is good for more than 2G, and less.
I just thought that DOS was only compatible with FAT12 but now I
remember it I think that you can have DOS on FAT16. However you cannot
have DOS on FAT32. Isn't it?
sda3 WINXP
If you do that, you'll almost certainly never be able to reinstall Windoz
without wiping out Linux first. All the WinXP installation CDs I've used
apparently check for the presence of Grub on the first primary, and black
screen instead of proceeding when I boot them.
Even if GRUB is in a ext3 partition ? Black screen ?
Hummm...
I have not so much experience on installing Windows XP so you might be
right.
Make sure that sda is an IDE partition. As far as I know DOS does not
support SATA drives.
DOS uses the PC BIOS for ATA I/O. DOS has no idea what kind of ATA interface
is hiding behind the BIOS. DOS might be incompatible with AHCI, which I've
never yet tried, but it works fine with both SATA and legacy modes on SATA
HDs on the several systems I've tried DOS on.
You are right. I was so stupid. It's true. DOS uses PC BIOS I/O so...
If you can run Grub legacy on a PC you can run DOS. (The only problem is
80386 architecture support I suppose).
