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 stand-
ard translation regardless of whether extended translation is
enabled. Drives handled by the disk driver
aspidisk.sys
will con-
tinue to use standard translation and not be capable of DOS
partitions over 1 Gigabyte.
What if I have more than two hard drives on the
AHA-1740A/1742A?
You can use up to seven hard drives under the BIOS provided
you are running DOS 5.0.
What if I use older versions of software drivers with ex-
tended translation enabled?
To protect your data, the host adapter will lock out any driver
that does not identify itself as capable of extended translation.
If you need to use software that is not compatible with ex-
tended translation, do not enable extended translation.
Adaptec's ASW-1410 v3.0a (and later) is the appropriate ASPI
manager software to use with extended translation enabled.
