#NEC/ADAPTEC-HELP!!
8 messages in this thread
Chris, run MFT (manifest) that comes with QEMM to find out where the ROM for
the SCSI controller is (exclude that). If you using stealth, XST (stealth
exclude that region). When you access the CD-ROM drive, does the light come
on? If so then at least the controller and drive are talking.
You know you need to load ASPI2DOS.SYS first before the CD-ROM driver right?
IF the two are not talking (or even if they are) then check the termination
of the SCSI bus. You will need a terminator on the SCSI controller (default)
and a terminator on the last unit on the cable (not default). If there is not
a terminator on the last unit on the physical cable, they you will need to
follow the directions for that device and place a terminator on the cable or
drive.
Also, you can use the switch /D with the ASPI2DOS driver (I think it's /D)
for more info. It will tell you if the driver sees the device. and what
number ID it's configured for.
Hope this helps.

I finally figured out most of what you suggested. I've tried several
cables, several terminators, tried _not_ terminating, the ASPI driver is
loading prior to the CDROM driver and excluded the appropriate memory
address. The Adaptec card sees the NEC but doesn't recognize it as an NEC
CDR-74 during the INQUIRY ar boot-up. I can switch to drive E: but I still
get a CDR101- not ready reading message. Seems to be baffling techsupport
(NEC, Adaptec, and Corel) too.
Thanks for your help, and if you can think of anything else, please l;et me
know.

Chris,
One idea, I too have an Adaptec 1522 and called Corel to inquire whether
their software would support my card. They said they weren't sure but if I
had ASPI4DOS.SYS then for sure it would. Well, being you are running
ASPI2DOS.SYS I wonder if Corel SCSI supports it properly. Might discuss
this with Corel tech support a little further…

For what it's worth- I'm now *convinced* there is a *real* problem in
interfacing a CDR-74 to a 1542B. I think the problem happens with the
*external* model 74 more than with an *internal* 84 because of some
weirdness with SCSI termination or such.
I found I get slightly better results with the terminator *removed* from
the CDROM drive, but eventually I get the CDR101 error also.
It's a real live problem, and it would be real nice if Corel, Adaptec, or
NEC could diagnose the problem and a fix…

I use the NEC 74 / Adaptec 1542b combo using the Adaptec Cdrom drivers and
ASPI4DOS without a hitch. Have you tried another adapter card to make
certain the NEC 74 is functioning properly? Take care. Brian Hinkle,

I'm using (or trying to use) an Adaptec 1540B/42B SCSI controller with NEC
84. It would run OK (could do a directory of a loaded CD-ROM). If I tried
to install 1-2-3 windows w/ multimedia help (from Program manager, File Run
D:INSTALL) it would flash the drive light a few times and then give an
insufficient memory error message. Using Grolliers I could access text for
a seemingly unlimited time, but some images would cause an error. After
either of these errors, if I tried a directory of D: I'd get the CDR-101
error message. Occasionally the system would hang.
ASPI4DOS and ASWCDNEC are loaded as devices in my CONFIG.SYS. I don't have
any documentation on ASWCDNEC, taht's something my reseller came up with.
I couldn't get it to work. I also bought, in the box, an NEC 74 and NEC
SCSI board. I installed that per NEC's instructions and it works fine
(took out he ADAPTEC & NEC 84)
Can you please give me some info on your configuration? Do you use
ASWCDNEC? Do you have any info on the parameters used with this driver?
Thanks.
Here's what's in my config.sys. I havn't had any trouble at all.
DEVICE=G:\QEMM\LOADHI.SYS /R:2 C:\ASPI\ASPI4DOS.SYS /D
DEVICE=G:\QEMM\LOADHI.SYS /R:1 C:\ASPICD\ASWCDNEC.SYS /D:ASPICD0
When I load Mscdex in the Autoexec.bat file it looks like this:
C:\QEMM\LOADHI /r:2 C:\aspicd\MSCDEX /D:ASPICD0 /m:12 /e /v
I have the cdrom at SCSI ID 3. Synchronous negotiation *must* be disabled
on the Adaptec. I have terminating resistors on the Adapter and the Cdrom.
Hope this helps. Take care. Brian Hinkle, Anaheim, Ca
Chris, if you load the ASPI4DOS.SYS driver with the /D switch (more info
switch), what SCSI number does it identify your CD-ROM at and what messages
do you get?
