Thanks very much for your assistance.
The drive does read CD-RW discs just fine (including that Debian disc)
under Windows (95 and 2000) using standard drivers. I was actually
surprised (and quite pleased) to see that and have never had any
trouble at all with CD-RW discs under Windows. FIWI, the CMOS
setting I'm using under Linux is identical to the one I use under Windows.
Is it even necessary to have a disc in the drive when pcd is loaded? I have
tried both commercial CD-ROM and CD-RW discs with equal results. In
my quest, I've seen dmesg samples posted which seem to indicate that
the drive itself responds to pcd with some return data, such as:
> pcd0: Sharing parport0 at 0x378
> pcd0: BACKPACK Protocol Driver V2.0.2ac
> pcd0: Copyright 2001 by Micro Solutions, Inc., DeKalb IL.
> pcd0: BACKPACK 2.0.2ac, Micro Solutions BACKPACK Drive at 0x378
> pcd0: Unit: 45 Mode:1 (8-bit) Delay 0
> pcd0: identify completion: alt=0x88 stat=0x88 err=0x188 loop=160001
> pcd0: Request sense before command: alt=0x88 stat=0x88 err=0x188
> loop=160001 phase=136
I don't get any of this. All I get is "adapter not found", "autoprobe
"no CD-ROM drive found". I get the same results whether the drive is
or not, so it seems to me like pcd isn't seeing the drive at all. I
never get to the
point where the drive will mount to read the disc, although I have tried.
Since my last post, I got a hold of setid.exe and confirmed that the
unit ID is
indeed 33 as it's supposed to be based on the serial number. I was
that this might have been changed way back when, but now I know we're using
the correct value.
Any further suggestions or ideas would be much appreciated. I suppose I
could live with Windows on this machine, but I'd really rather not have to.
