Hi ... this is addressed to both the general CD-ROM list (CDROM-L) and
the one for networking (CD-ROM) - hopefully some of you may have faced a
similar problem and have solved it -- if you reply, please do so to me
privately, as I am not on either list   (BASTILLE@GRIFFIN.UGA.EDU)

I have two CD ROM systems hooked up to a 80386-20SX system, Monochrome (IBM
original) monitor, Micropolis ESDI 1355D (150MB) hard drive, a Micropolis
1558-15 ESDI dual floppy/hard disk controller.  The motherboard of the
system has AMI 386-BIOS (1989 for MB-1316V, DVLX-1223-040990-KF).

The two CDs are an Hitachi TCDR6000 which has it's own 8bit controller (came
with the TCDR6000)  and a Pioneer DRM-600 (it has had a BIOS upgrade so it's
probably equivalent to the DRM-600A) that came with a Future Domain SCSI
8 bit adapter (SCSI 1, SCSI 2 command set compatible).
The HITACHIA.SYS device driver is V2.10 .  The Future Domain SCSI device
driver is "CD-ROM Device Driver V1.01 Future Domain" and "LDP/CDP Device
Driver for SCSI V1.00") and is DRD600.SYS.  We are running the system under
MS-DOS 5.0 with a SETVER for MSCDEX V2.10 at DOS 3.30.  MSCDEX usually loads
the Hitachi device first (it's drive D:, the Pioneer is drives E: to J:).

The Hitachi and Pioneer worked fine in the system when an MFM SEAGATE 251
hard drive and Western Digital controller were in the system.

PROBLEM:
The Hitachi works fine now, but the Pioneer is hit/miss, with or without the
Hitachi drive controller in the system.                          -------

When I do a DIR on a CD-ROM in the PIONEER changer, sometimes it gives
me a listing of all the files, other times not. Sometimes the directory
table appears screwed up (non-stnd ASCII characters are returned).
I usually run the Silver Platter (V3.0) software to access several
different Agriculturally and Biologically oriented CD-ROMs.  It may run
but often returns a SilverPlatter system error of 8206 ("system error -
reboot, etc.").
In either case (bad DIR results -or- 8206 SP error and reboot), if I
eject the 6-pack carousel, and reinsert it may work!  Or it may not, until
eject-reinsert is done several times --- IT USUALLY DOES EVENTUALLY WORK
WITHOUT A COLD BOOT!!  (Even a normal cold boot doesn't guarantee it working).

I made sure there are no address conflicts between the SCSI and the ESDI
(tried every possible mapping combination -- one aside, when I had an SVGA
in the system, I couldn't get the system to even boot (double beeps during
POST) even though the VGA-ESDI-HITACHI-no PIONEER-MOTHERBOARD-DOS5 combo worked
and so did the VGA-MFM-HITACHI-PIONEER-MOTHERBOARD-DOS3.3-or-DOS5.0 combo --
Again, there were no conflicts in address space in VGA-ESDI-PIONEER-HITACHI-
MOTHERBOARD,  but it DID NOT work).
The SCSI appears in a higher mapped area than the ESDI (per Future Domain's
Tech Support - didn't help).  I tried a config where I introduced a wait
state in the 386SX motherboard (with either 0 or 1 wait, only choices).
Disk Caching is disabled.  My CONFIG.SYS has Buffers and Files set to 50
and FCBS set to 64,32 (tried 40 , 30 and 0,0 respectively as well). No other
TSRS are loaded.

HAS ANYONE GOT ANY SUGGESTIONS??????
