Oki, got it.

So OpenBSD requires one of those precious partitions.
I think I got that one too.

My current plan is to boot Win95, OpenBSD and three (3) Os/2's.

I use Docsboot+, it boots everything I have tried.
I recommend it, check www.docsware.com for more info,
BTW, I don't sell it, I'm just a satiesfied customer.

Does that appy to SCSI too? I don't use IDE drives.

Well, I think I have to downgrade my plans to only
2 Os/2 boots, sigh. Well, I think I can live with it ;-)
(And no, I'm refuse to boot Os/2 from D: or an extended
partition, it messes up those f**king drive letters)

- No, that's wrong. It's the language that God need to speak
when he is trying to communicate with Un*x programmers.
- Ehh, why should God want to communicate to Un*x programmers?
They usually admire d(a)emons, so they aren't Gods business.
- Yeah, but the occational cuss and stuff is still communication.
