EISA-to-Fast SCSI Host Adapter

Disk Drives Over 1 Gigabyte

Using Fdisk

To install a new disk, or to re-partition an existing disk, use the fdisk DOS utility as you normally would. The cylinder size in- creases to 8 MBytes when you enable extended translation. The size of the partition you request must therefore be a multiple of 8 MBytes. If you request a partition size that is not a multiple of 8 MBytes, fdisk will round up to the nearest whole multiple of 8 MBytes.

Load ASW-1410 v3.0a

Load ASW-1410 v3.0a for ASPI support of non-disk peripheral de- vices. The ASW-1410 v3.0a is fully compatible with extended translation in the AHA-1740A/1742A.

Questions and Answers About Extended Translation

What happens if I enable extended translation with SCSI drives that are less than 1 Gigabyte in capacity?

Drives handled by the BIOS will use extended translation pro- vided they are over 1 Gigabyte in formatted capacity. Drives with less than 1 Gigabyte of formatted capacity will use standard translation regardless of whether extended translation is enabled. Drives handled by the disk driver aspidisk.sys will continue to use standard translation and not be capable of DOS partitions over 1 Gigabyte.

What if I have more than two fixed disk drives on the AHA-1740A/1742A?

You can use up to seven fixed disk drives under the BIOS provided you are running DOS 5.0.
