Someone has experience in scripts and perhaps has a dualboot OS4.1 / OS 3.9 install ? I tried this script http://de.aminet.net/aminet/docs/help/D ... ing_EN.pdf but it gives priority to the OS4.1 installation. This is a problem because OS3.9 sits on the blizzard scsi and OS4.1 on the motherboard's scsi. Basically the OS3.9 installation can see the OS4.1 installation but the other way around can't because OS4.1 has no driver for the Blizzard's scsi controller. So the scripts makes OS4.1 look on the OS3.9 partition it doesn't. The other way around would be no problem.
I could put everything on the ide drive but that's not really optimal for the 68k side that I wanted on the faster BPPCscsi.device
