Problems with Mitsumi CD-ROM under OS/2

[Ron Vyhmeister]

Hi! I've been trying to get my Mitsumi CD-ROM drive to work under
OS/2. I'm running the March 2.1 beta on a 486. My friend has the
December beta and a second Mitsumi drive. We've done things
independently, using the LU005S.ADD driver, and all we get
when we try to access is a SYS0026 error. We have no problems
accessing the drives from a DOS VDM.

The only thing in common which we have is that both of our drives
are relatively new (mine purchased in April, his in May).

Does anyone have any suggestion? Are we the only ones having this
problem?

Thanks.

We need to determine if the April 1993 drive is the problem. Please post
info regarding whether or not your drive works with either os/2 driver and
the date of manufacture of the drive. Thank you.

I have spoken to Ron about this, and have tried the german driver
myself. Neither driver works. Both yield SYS0026 when an attempt is made to
get a directory of the CD-ROM in the drive. Ron's drive has a date stamp of
March 1993. I haven't checked my drive, but it had MSCDEX 2.2 software bundled
with it, so it probably safe to assume that it is also very recent.

It is probably also a good idea to consider the controller. We both
have 16 bit controllers with the drive, which I think may be a new thing. Is
it possible that Mitsumi may have been previously using a different controller
card (i.e. one that was 8 bits)?

Another thing I tried was to copy the install disks and place the CD-ROM
driver into the install disks' CONFIG.SYS (in hopes of ruling out anything
specific to my software installation). I added the following:

IFS=CDFS.IFS /Q
BASEDEV=LU005S.ADD
BASEDEV=OS2CDROM.DMD

BTW, I could find no online documentation for CDFS.IFS, even though I
found a reference to such docs (which pointed me at the command reference). So
I don't know what switches are possible with it. However through
experimentation I've found that "/Q" means "quiet". Remove the switch and
CDFS gives verbose information about its installation (none of which was of
any help).

Then I booted the install disk(s) and tried again. Same error code.

I have access to another machine with an earlier Mitsumi drive
installed (D.O.M. before January) and will try the same experiment with the
floppy-boot there. This may yield a few more clues.

I am using the DEC Beta.

This is the same symptom I am having with an LU005 purchased early this month.
I have the latest (update2.zip) version of LU005S.ADD, and I cannot access
the drive. I'm still going to get the 2.1GA on CDROM, though; I just hope
by then I won't have to make ~30 diskettes from it.
