Hi John - nice to see you again.

You can replace BM with grub - you can even daisy chain grub and BM
(bog knows why you'd want to.)

Grub, as I suspect you already know, is the much simpler to use
replacement for LILO - in short, a boot manager. Porting it to OS/2
would be sort of silly, since by the time OS/2 has booted enough to
run it, it would be redundant.

Going from memory here, having played around, unsuccessfully with
Lilo, to do the same thing on my laptop, with OS/2, Win98 and Limux,
there is a very real possibility that you also need to 'makehidden'
any other active partition.

I never did get it working properly... and then I munged the partition
table and blew away the Linux partition. I suspect that one of the
reasons for the failure was that I tried (I really really tried!!!)
and suceeded in attempting to boot with 2 TWO! active C: partitions...
Luckily, I was able to fdisk /newmbr from a floppy boot...but all of
the two-step boot with Lilo was lost..

.... boot manager. no reason to - it's OS agnostic

It's the GRand Unified Booloader from the Free Software Foundation.

It may not be necessary. If it supports the filesystem, you can write the
necessary files to a floppy disk, boot the floppy, and install it.

However, I don't have an "hpfs_stage1_5" on my (Linux) system. Does that
mean GRUB's configuration files can't be loaded from an HPFS partition?
