SYM53C4xx SCSI Interface Adapter Cards


These questions and answers are for any SCSI interface card that
uses any Symbios Logic (or old NCR)53C400, 53C400A, 53C406, and
53C406A chips and connects to an ISA bus in the host.

This document uses scanners as the sample device. This Q & A
will apply to any device that provides a scsi interface card as
its interface to a computer.

1. Are there drivers available for my card to operate under any
operating system besides DOS?

We provide the chip and sometimes the interface card, BUT all
driver upgrades would come from the manufacturer of the device.
The device driver for that card was developed by the company that
manufactured the scanner attached to the interface card. Usually
attached externally using the 53C400 or 400A scsi chip.

2. I would like to attach another device to the cable that
attaches the scanner to the computer, can this be done?

No, There is no SCSI bios associated with this card. Its only
function is to INTERFACE to the device using the drivers
installed in the config.sys and Windows 3.1 SYS.INI files. To
use both devices on the same cable you will need to purchase a
SCSI host adapter card (HBA) with bios support.

Important!
Verify that their are drivers available for both devices with
the new HBA. Some Companies may not provide additional drivers
for their device other than the interface driver.
There are several removeable media devices that can work with
the supplied driver and an aspi interface. We cannot guarantee
that the data would be compatable in other systems or operating
systems.

3. I have a MediaVision Pro Audio Sound card, are there any
drivers for this card to operate in protected mode for
win95 or OS/2.

The driver MediaVision contracted us to suppy was for operation
in a dos format only. There has been no contract agreementfrom
MediaVision to develope drivers for other OS's.

4. I would like to eliminate the scsi interface card in my
system and connect My scanner to an external port on my scsi
host adapter card, can I do this?

Yes, provided the manufacturer of the device provides a device
driver for the scanner to operate from an pci/host adapter card
that has a Symbios Logic scsi processor chip on it.
