Dos/Windows Performance - Adaptec AHA-2740W User Manual

Send Start Unit Command is disabled (set to no) by default. Check
your hardware documentation before you enable (set to yes) this
option to make sure your devices support it. Then change the switch
or jumper settings on the device to enable the option. To enable/
disable Send Start Unit Command, See Device Configuration on page
3-13.
Try enabling Send Start Unit Command for one peripheral at a time,
rebooting each time to make sure each SCSI device works properly.
(Some older disk devices do not support this option and may mal-
function if they receive the command.)
Note:
The Send Start Unit Command has no effect if the host
adapter BIOS is disabled.

DOS/Windows Performance

Adaptec's EZ-SCSI I/O Operating Environment Software is
designed not only to simplify installation of device drivers under
DOS, but also includes ASPI management software to provide
Virtual DMA Services (VDS) support and enhanced Windows sup-
port. The drivers that are installed will give DOS users the best per-
formance possible under not only DOS, but Windows.
