Q. What is the "Write Verify" configuration option?

A. Each configuration option

0./0

base address

/REQ

/ DMA) can be configured to

"Write"

"Write Verify". For example, for a host adapter

port 330H, IRQ 11,

and

DMA

channel 5, option 1 should

used for "Write" only

option 25 for

"Write Verify". Standard "Write" will use the SCSI write command when writing

data

the hard disk. "Write Verify" will use the SCSI "WriteVerify" command

when writing to the disk drive.

the SCSI "Write Verify" command

not

supported by a particular drive, then the SCSI "Write" command followed

the

SCSI "Verify" command will

be used.

The "Write Verify" option will decrease overall system performance, but offers a

higher degree

reliability. In general the "Write" only option is usually

sufficient.

Q. Will my AHA-1540/1542 work in every AT compatible system?

A. The AHA-1540/1542 is a bus master DMA device, and requires that the host

system support bus master DMA.

a particular host system does not support bus

master DMA, the AHA-1540/1542 (or any other bus master board) cannot

used

in that system.

A test is built into the AHA-1540/1542 BIOS that can

used to determine

the

host system supports bus master DMA. It can be invoked by using DOS

DEBUG.COM. At the DEGUB "-" prompt, type

G=DCOO:9.

The

instruction

will be printed on the screen. This assumes your AHA-I540/1542 BIOS

configured for

DCOO.

Q. Can I use my AHA-17400r AHA-1744 with NetWare 286 using the ASW-1440

v3.0?

A. The AHA-1740 and AHA-1744 have two operating modes; standard and enhanced.

Standard Mode emulates the AHA-1540/1542, so the NetWare 286 drivers can

used when the AHA-1740/1744 is in standard mode. Enhanced Mode uses an

advanced host interface and allows greater than 16 MBytes

hOst

RAM

accessed. However, no driver for enhanced mode for NetWare 286 is provided with

the ASW-1440 v3.0.
