But an improvement can also be to interface a _real_ SCSI disk and send d= irectly=20 to it the SCSI commands generated by the _virtual_ SCSI interface (as it = is done=20 in BasiliskII emulator) > (I didn't notice any)? Can the PC boot from a SCSI-mounted device (I di= d > not succeede)? To be able to boot from a SCSI disk we need a BIOS extension managing the= SCSI=20 card and allowing the BIOS to load the boot sector from the SCSI disk.
