BeOS No Longer Bootable!!

[MYOB]

I have got Mandrake 9.0 installed and working now, and I get offered two boot loaders: first, the Mandrake one, which i think is GRUB, and then if i pick Windows, the XP one. Neither can boot BeOS. I have a second BeOS Dano install on an backup partition on a second HDD, and can boot this by floppy, but it can no longer see the BeOS 5.04 on the first HDD

my drives are like so:

HDD1: partition 1, XP (FAT32)
Partition 2, 98 (FAT32)
Partition 3, BeOS (BFS)
Partition 4, Mandrake (EXT2 [have tried it as EXT3])
Partition 5, Linux Swap (umm......)

HDD2: Partition one, unused FAT32
Partition two, BeOS Dano (BFS)

BootMagic in XP does nothing, just allows me to boot XP/98.... it can't see the BFS partition either

Wait... I'm getting there!

BeOS, XP, 98 now booting, trying to get Mandrake back up and booting

If you have booted BeOS successfully, install its Bootman. It should boot all of your operating systems, if you just choose the right partitions while installing it.

umm.... no

it can't boot Mandrake... assuming i am right in selecting the normal and not the swap partition to boot from?
