Hi.
I think you have to install the driver as supboot.sys in the root directory. Probably you will need to do this with a special tool which should be with the drive or which you should try to get from someone who has it.
Are you able to let the driver run from the auto-folder of a floppy disk?
Else: Does anybody here know wether one can use other drivers with vortex drives? (It is a vortex drive, isn't it?). Scsi-tols and Hddriver don't work with those drives. Perhaps any others?
