LILO fails to load DOS on /dev/hdb

LILO fails to load DOS on /dev/hdb

You need to remap BIOS drive 81 (hdb) to 80 (hda)
since DOS can start from BIOS drive 80 only.
I can't remember proper options right now but it
shall be somewhere in HOWTOs or LILO man page.

The next day is never so good as the day before.

1. LILO: booting DOS from /dev/hdb -- SOLVED!

I posted a couple of days ago asking how to configure LILO to boot MSDOS (yuk)
from /dev/hdb1. I had a number of helpful (but ultimately misguided!) replies.
Thanks for your help everyone - it's nice to be a member of such a friendly
community! Anyhow, for those interested, here is the answer: use any_d.b
as a loader ...


        install = /boot/boot.b

        image = /vmlinuz
        label = linux
        root = /dev/hda1
        vga = 1

        other = /dev/hdb1
        loader = any_d.b  <<<< NB:
        label = msdos
        table = /dev/hdb

I got the LILO docs from Sunsite, any_d.b is documented, kind of. It says it
exists and hints that it 'swaps the drives 0 and 1 around, whatever that
means) Anyhow, I thought it worth a try so I did!

This should (IMO) be better documented ...

Thanks everyone.
