Can I Have Two Operation Systems On The Amiga

1.3 / 3.1 / 3.5 / 3.9 / UnixPPC / MOS / et now I added OS4 on my 1200PPC

I'd sure like to know how you did Workbench 1.3 installed on an A1200.  As soon as you go to a 1.3 kickstart, you lose access to your hard drive....

By any chance ... is this only possible with an installation of OS4?

Naw.. you can set up a multi-boot on any AmigaOS versions around.  I had my old A500 set up with 1.3 and 2.1 (No reason you couldn't do 3.1, as well, just it wasn't out way back then!)  

What I did was have a bootable DH0: with an s:startup-sequence in it that loaded just enough minimal files to boot to a menu.  Each option on the start menu had an associated S: script which would rekick a kickstart, if necessary, move the assigns and mounts to whichever OS version I wanted to boot, then it would hand-off to the s:startup-sequence for that OS.  It was pretty slick for 1992.  :lol:

I don't use a softkick, I just "copy all" the WB1.3 to a small 20mb FFS partition for some old games.

So you're booting Workbench 1.3 on a 3.x ROM?  I didn't even know that would work...  Is there actually any compatibility benefit to doing this, though?  I thought pretty much every game that barfed on 3.x did so because of the ROM, not because of Workbench.

When you switch to a 1.3 ROM, you lose the A1200 scsi.device (on-board IDE driver).  Filesystem on the hard drive doesn't matter, as no hard drive controller drivers exist in 1.3 ROM.
