Hey there, I am looking for a boot-switcher to choose booting from either DOS or UNIX partition at startup-time. Unitl now, I have to switch the active partition using fdisk all the time. That's annoying, isn't it? Bye, Henning Moeller.

I solve the problem by making the unix partition the active partition and boot DOS from a floppy. I leave the dos diskette in drive a: and open the drive door whenever I want to boot up unix.

When I had a Xenix/DOS system, I wrote batch files (for DOS) and scripts (for Xenix) that redirected input into fdisk, thereby automating going back and forth between them. This is no great trick; you can redirect input into fdisk or its analogues under virtually every version of PC Unix. For xenix in particular, you can always leave the Xenix partition active and type 'dos' at the colon prompt when you turn your machine on. This is a little stub loader that boots the DOS partition. I would read the manuals for your Unix flavor; or call tech support -- this is such a universal problem, the vendor may already supply a solution.

With SCO UNIX and XENIX you can set up the SCO OS as active partition, and at the SCO boot prompt, enter either "unix" or "dos" and it will then proceed to boot the selected system for you. -- Dion L.

It looks at the keyboard just after trying the floppy and will boot off partition 'n' depending on which numeric key one has pressed... One could either buy COHERENT for $99 just for this feature, or hack together a bit of code based on microsoft's version which currently scans the partition table to find the bootable entry. I'll try to throw something together suitable for posting. (I'll even resist the urge to scan mwc's code first - for hints and such)

There are two versions, because if you use one of the partition managers (such as Disk Manager) they use part of the boot sector and must not be stomped on. The difference in the two versions is that one has a menu and allows unattended auto-boot of the desired partition. The other one cannot auto-boot, there must always be an operator to select the partition. The program allows you to save your existing boot sector and try either of the programs. If there is a problem with the auto-boot version for example, you can re-load without losing your partitions. This program runs under Unix (if you haven't got Unix, you don't really need it, eh?), is in source form. I *really* appreciate having it. I don't know where the appropriate place to post it would be: since it runs on Unix, and isn't binary, c.b.i.p. seems like a strange place to put it. Since it is only usefull if you are running multiple OS, putting it in c.s.u. doesn't seem right either. I got it out of comp.unix.sysv386 a month or so ago. If I got it off the net, is it fair to put it back on the net without checking with the author? Give feedback, and I will do what seems appropriate. -- del AKA Erik Lindberg uunet!pilchuck!fnx!del Who is John Galt?

I recall a program called MFBOOT that appeared in MINIX group some time ago, that enabled selection of the boot partition. I can dig up my archive if needed, or better, maybe the original post can be located at the minix archive site.
