I didn't see a mention of the hardware you run on,but i'm using it on my A4000t and a4000 medaitor setups fine. the easiest thing to do is to boot with the os4 floppy,and use the hd tools there to partition the drive and add SFS,just run it and change the filesystem to sfs/00 for each partition.
also,make sure u dont have vga only checked in the os4 installation if you have a scan doubler/flicker fixer(picasso IV here in use).
hope that helps,
