Hello,

I have two IDE disks with the following Operating Systems:

IDE-0 --> ad0s1 --> Windows XP Pro
          ad0s5 (extended) --> Windows 2000 Pro

IDE-1 --> ad2s1 --> Debian Sarge (managing LILO at IDE-1)
          ad2s4 --> FreeBSD 5.3

I boot from the second disk. I have LILO in the MBR because it is
capable of "swapping" disks when loading the operating system (Windows
does not boot because it thinks the disk which the computer boots is the
first disk, and boot.ini refers to the other disk).

So I have to put the following:

other=/dev/hda1
label=Windows
map-drive=0x80
to=0x81
map-drive=0x81
to=0x80

Or:

other=/dev/hda1
label=Windows
boot-as=0x81

Can I do something similar with other Boot Managers (FreeBSD's Boot
Manager, GRUB, etc.)

Which is the better recommended multi-boot layout (with two hard
disks)?

Thanks and Best Regards,
Ale
