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.

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.

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.
