Enhanced Mode OperationThe enhanced mode operation enables the adapter BIOS to iden-tify all installed fixed disks with a valid SCSI ID.All SCSI IDs with the BIOS support option enabled, using theEISA Configuration utility, are scanned. The devices arescanned, starting from SCSI ID 0 and increasing until two SCSIfixed disks are found or all supported SCSI IDs have beensearched. Those devices found that are not valid fixed disks, suchas SCSI tape drives, CD-ROM drives, etc., will not be installed.However, the SCSI Inquiry data, the manufacturer and modelnumber for these devices, is shown.The following message appears when you boot the computer sys-tem with the enhanced mode operation selected.Installed devices display the SCSI Inquiry data followed by thedrive C (80h) or drive D (81h) designation. Drives 82h through8Fh are supported with the adapter BIOS running DOS 5 orhigher.Adaptec AHA-1740 BIOS v1.34Copyright 1991 Adaptec, Inc.[Standard Mode]Target 0 - QUANTUM P40S 940-40-94XX - Drive C: (80h)Target 2 - CONNER CP340 (40mb 3.5) - Drive D: (81h)Target 4 - CHINON CD-ROM CDS-431Figure 6-2.
