ATAPI CDROM problem (NEC-260)
Hi everyone,
I'm really green, so pardon me if this is in a FAQ, but I did search
the archives for this problem to no avail.
I have an NEC IDE/ATAPI CD-ROM. It says "CDR-250" on the case, and
the BIOS reports "NEC ATAPI CDROM: 260" (or something similar to
that). I'm having trouble getting it to be recognized by Debian
Linux ("Hamm" release, version 2.0.2 on CD from Linux Systems Labs).
Using a DOS boot floppy with the NEC driver and MSCDEX, I am able to
read the CD, which convinces me that it is not a drive or cable
problem. It is jumpered as a "slave" on the primary IDE controller
(on the motherboard).
Examining the dmesg output I found the following, which would seem
to be the problem:
ide: i82371 PIIX (Triton) on PCI bus 0 function 57
ide0: BM-DMA at 0xf000-0xf007
ide1: BM-DMA at 0xf008-0xf00f
hda: SAMSUNG VG38404A (8.40GB), 8056MB w/490kB Cache, CHS=1027/255/63
hdb: NEC CD-ROM DRIVE:260, ATAPI cdrom or floppy?, assuming FLOPPY drive
ide-floppy: Packet size is not 12 bytes long
ide-floppy: hdb: not supported by this version of ide-floppy
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
Floppy drive(s): fd0 is 1.44M
FDC 0 is a post-1991 82077
[complete dmesg output after message]
Apparently the OS is making an incorrect assumption
about the identity of the device and then failing
because of it. (Ever heard of an IDE floppy? I've
certainly never seen one). Anyway, after booting,
there is no /dev/hdb device to mount.
I don't know what I can do about this. Surely there's
some way to "nudge" Debian in the right direction?
(I have installed the basic part of the OS from floppy
disks, so it is possible to tinker with the configuration
files).
-------------
As an alternative, I have a Creative Labs "Infra-1800" CD-ROM
which is a 12X with a gimmicky infra-red remote. I figured it
would be better to leave that on the Windows machine. It's also
an "ATAPI IDE CD-ROM." I would expect it to have the same problem,
but I'll probably try it if all else fails.

Many thanks!
