Hi,
the "SoftSCSI_ATE9.device" is not a real scsi/at-device.
It makes the Oktagon able to load a real scsi/at-device from HD.
Just like softkicking Kickstart.
If you read the whole manual of oktapus you'll understand...
You can install the driver...
in SYS:Expansion (Binddrivers)
in RDB of the first HD
in any other folder and start it manually (for testing it...)
or load it with LoadIDE (IDEFix) to make it reset proof - Autoboot with TandemIDE :-o
:-D
