8590 SCSI CDROM annoyances
Tim Knight/CT
again.................
I have an 8590 with a Future Domain SCSI adapter running 2 hard drives
and 1 CDROM internally......plus a Nakamichi MBR-7 disk changer
externally. All drives function well using PCDOS7.
Small problem:
1. If I try to run both CDROMs using the FD driver, the disk changer
only shows up as 1 drive instead of 7, and the onboard shows as 1
drive.
2. If I try using the Nakamichi driver in conjunction with the FD
driver, I get 9 drives instead of 8. The onboard CDROM shows up
twice obviously (I think) using both drivers.
I have used the /L switch to assign a single letter to the onboard
cdrom, but it still shows up as 2 drives.
Can anyone give me a simple way to eliminate my double-vision?

All of the CDs in either of the drives can be read with no problem.

OK, 2 questions please:
1) is this an "IBM PS/2 SCSI-2" adapter or a "Future Domain MCS700"? i.e.
which ROM BIOS chip does it have?
2) which Future Domain CD-ROM driver have you tried, with which other FD
drivers?
If you paste a couple of example config.sys DEVICE= listings here that might
help.
P.S. I have all the devices and adapters you've mentioned and know most
bugaboos that may occur.

IDMCA tells me it is an IBM PS/2 SCSI-2 with an ADF 60E9

Config.sys:
DEVICE=C:\PWRSCSI!\DCAM18XX.EXE /APM
DEVICE=C:\PWRSCSI!\INT4BCAM.SYS
DEVICE=C:\PWRSCSI!\FDBIOS.SYS
DEVICE=C:\PWRSCSI!\ASPIFCAM.SYS /D /O
DEVICE=C:\PWRSCSI!\FDCD.SYS /D:MSCD0001
DEVICEHIGH /L:2,4560 =C:\WINDOWS\IFSHLP.SYS
STACKS=9,256
DEVICE=C:\MBR7ASPI.SYS /D:MSCD0002
Autoexec.bat:
LH C:\MSCDEX /D:MSCD0001 /M:10 /D:MSCD0002 /M:10
The driver MBR7ASPI.SYS is, of course, the driver germane to the 7-
disk changer.

What if you took the Future Domain CD-ROM drivers completely out of
the picture?
Since it appears that the Nakamichi changer driver will also find the
single CD-ROM, it's worth a shot.

Okay, what you need to do is:
1) replace FDCD.SYS with IBMCDROM.SYS /D:MSCD0001 /I (this ignores the use
of non-IBM drive identities, allowing the Nakamichi to be usable by this)
2) remove MBR7ASPI.SYS and, optionally ASPIFCAM.SYS (provides ASPI manager
which isn't necessary without the MBR7ASPI.SYS, unless Win9x sits on top,
perhaps)
3) use MCAM18XX.SYS instead of DCAM18XX.SYS, it's better for multi-tasking
etc. the switch may or may not be the same for these two drivers
4) remove the trailing reference to /D:MSCD0002 /M:10 from MSCDEX, as we
only need the IBM (Int 4Bh using, as provided by INT4BCAM.SYS) CD-ROM
driver
and then you're done. Reboot.
(Back at you CT. Well the beer/ale isn't deep-frozen, and it's still as
flavoursome and satisfying as ever, thanks for asking) ;)

If I remove the Future Domain CDROM driver, only the 7 drives of the
changer appear, i.e. E/F/G/H/I/J/K.
If I remove the Nakamichi driver, the onboard CDROM appears as drive
F, and the changer appears as drive E........but the remaining 6
drives are not listed.
I think the problem lies in the FD scsi adapter, but do not know how
to correct it.

See my post in the other branch. Cheers.

Didn't work for me. Every time I loaded IBMCDROM.SYS /i , the machine
hung as it was going in. I even tried deleting the Future Domain
drivers one at a time until they were all gone......and then it
loaded.
I am going to do a complete software rebuild and get back to basics,
and then try again.
Thanks old chum......tomorrow is another day....

Let me try the precise setup you've got and report back, I was so very sure
that my recommendation would work!

SCSI Id.s don't matter for this test, but I'll stuff one of my Pioneer 6-CD
changers on there to demonstrate co-existence. FWIW, with the FD adapters
with IBM ROMs the order of scan is 0-6, and with FD BIOS, if enabled, 6-0. I
put HD's "first", 0-2 on IBM chains, 6-4 on FD chains. The CD-ROMs come next
and lastly portable, removable HDs (SyQuest and Zip/Jazz) and scanner or
similar. You might want to adopt this technique on all your systems for easy
of swapping the external devices.
My Nakamichi is internal, but that's irrelevant to the test.
