Adaptec 1742A, AHA-1740A, 1744 user manual Enhanced Mode Operation, 2. Enhanced BIOS Boot Message

EISA-to-Fast SCSI Host Adapter Host Adapter BIOS Operation

Enhanced Mode Operation

The 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 the EISA Configuration utility, are scanned. The devices are scanned, starting from SCSI ID 0 and increasing until two SCSI fixed disks are found or all supported SCSI IDs have been searched. Those devices found that are not valid fixed disks, such as SCSI tape drives, CD-ROM drives, etc., will not be installed. However, the SCSI Inquiry data, the manufacturer and model number for these devices, is shown.

The following message appears when you boot the computer sys- tem with the enhanced mode operation selected.
