SCSI Parity Checking on the host adapter, See SCSI Parity Checking on
page 2-17. Consult your hardware documentation for instructions on
enabling SCSI Parity Checking on peripherals.
Note: The only time you should disable SCSI Parity
Checking on the host adapter is when your system
includes a SCSI device that does not support this
option. Again, consult the hardware documentation for
the device.
Setting Enable Disconnection
In the DOS environment you can increase performance slightly if
you disable SCSI Disconnection when there is only a host adapter
and a single disk device on the SCSI bus. You should enable this
option, however, if you have more devices on the SCSI bus.
Fast SCSI Operation
If you have SCSI-2 devices, and would like to transfer data at
10 MBytes/sec, Fast SCSI Operation must be enabled. When Fast
SCSI Operation is enabled, the total length of all cables (internal and
external) connected to the bus should not exceed 3 meters to ensure
reliable operation.
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
enhanced Windows support. The drivers that are installed will give
DOS users the best performance possible under not only DOS, but
Windows.
