Has anyone out there had any dealings with SCSI? I am refurbishing an old PC with a 486 Processor and basic bits that have all worked successfully in various configurations. The intended combination now is a Quantum 80 Mbs EIDE as the boot drive plus another Quantum SCSI 500Mbs as the data store. All works OK including the SCSI BIOS 'seeing' the 500Mg as Drive D. However the boot drive, at the moment running DOS 5 does not 'see' the SCSI drive at all and greets access attempts with 'Drive not valid'. All cabling and jumpers are set correctly and the host adapter (Adaptec 1542F) is recognised as ID 7 and the drive as ID 0. Apart from a little 'percussive technology with a Birmingham screwdriver' I am at a loss. It's not the end of the world if it doesn't work but if any of you Gurus have any suggestions, please be suggestive ! !
