The Microtek MS-PCZ Card

The Microtek MS-PCZ interface card is an 8-bit ISA SCSI card which uses a
memory address in the range above 640KB and below 1024KB area of your
computer's memory to communicate with the scanner.
The MS-PCZ card works only with Microtek scanners; you cannot connect any
other SCSI device to it. If you wish to connect multiple SCSI devices to one
card, you should consider purchasing an ASPI-compliant card such as the ones
manufactured by Adaptec.
The MS-PCZ card used to be shipped with all Microtek SCSI scanners but
Microtek no longer provides this card with its scanners. Instead, a new
interface card, the MS-PNR, is supplied with the scanners.
To identify the card that you have, look on the identifying label on your card. If
your card is labeled MS-PCZ-2, ignore this section and go to Appendix E,
which talks about the MS-PNR card, since the MS-PCZ-2 is really an MS-PNR
card.
Another way to identify PCZ and PNR cards is to look for jumpers on the
card. Cards with 3 jumpers are PCZ; cards with one or no jumpers are PNR
cards.
Using the jumpers with the MS-PCZ card
The three sets of jumpers on the MS-PCZ card allow you to change the
memory address of the card, but the default memory address is D400 hex with
all three jumpers installed in place. The MS-PCZ card uses 16 KB of memory
space. So, if your card is set to its default of D400, it uses all the addresses up
to but not including D800 — namely D400 through D7FF.
It is possible that memory management programs such as QEMM, EMM386 or
others use most of the area between 640KB and 1024KB as RAM, and there-
fore, conflict with the MS-PCZ's memory address selection.
In order to avoid these types of conflicts, add the "device" line below to your
config.sys file if: a) you're using HIMEM.SYS; or if b) you're using
EM386.EXE in addition to HIMEMSYS.
device=c:\dos\emm386.exe NOEMS x=D400-D7FF
