I recently bought a Chinon 4x ATAPI CD-ROM and wish to install
Slackware 3.0. I have two IDE hard drives on the primary controller,
and the CD-ROM is attached in single mode to the secondary controller
on IRQ 15, 0x170. I made the boot disk with the idecd kernel image,
but it does not detect the secondary controller, and I have been
unsuccessful in forcing the detection. I have read all the faqs and
docs and either I overlooked it or it just isn't there. hdc=cdrom
does *not* work.

To make a long story longer, what parameters do I need to pass to
force detection??

Thanks for any help!

after posting I found my answer via Alta Vista! While Chinon says
that you should set the jumpers to SINGLE (i.e. no jumper) if it's the
only device on the controller, in reality you need to set the jumper
to MASTER even if it's the only one on the controller. Then at the
boot: prompt I just entered "ramdisk hdc=cdrom" and all's well...
sorry for wasting anyone's time! ;-D

Would cdrom=hdc help? I don't know. I don't have IDE CDROM.
You sure your CDROM is set to MASTER? This is a common mistake.

Are you also running DOS or Windows on this machine? Michael's comment
about making sure the jumpers on the cdrom are set to master are valid,
but if the cdrom is working under DOS or Win then that isn't the
problem. You mention that you used an idecd kernel image, but that may
not be enough. Most distributions ask you what type of ide cdrom you are
using. If your cdrom is using the ATAPI interface then that's what you
choose, regradless of who made it. Were you given this choice? A generic
ide cdrom kernel may not work is that kernel isn't defaulting to ATAPI.
Good luck

Sorry, but that's quite false. Many of the DOS and Windows CD-ROM
drivers -will- detect a CD-ROM if it is set to slave mode, even if it
is the only drive on that controller. Even better (or worse, in light
of the above misleading comment), they will usually work when the
drive is set like this. I know because I've seen it happen and I've
witnessed it myself on my own computer.
Almost all CD-ROM drives come from the factory set to -slave-
mode, as they assume you are running a one hard drive/one disk
controller setup, and will be adding the CD-ROM as a slave to
your H.D. If you don't remember changing the jumper position on your
CD-ROM before you installed it, I can practically guarantee you that
it is set to slave.
You can also watch your DOS startup messages carefully...
I don't know about other driver flavors, but the MTM ATAPI/IDE device
driver will -tell- you whether your drive is master or slave
when it is called from within your AUTOEXEC.BAT, watch closely!

Not necessarily. I work on Packard Bells, Acers, and Gateway computers,
and I've seen just about any combo of slave/master setups. You can't
really assume that it is set to either - if you need to know, you
*have to open it up* and look at the jumper. It's too unpredictable to
guess.

well this is a hack and it worked with my PPro 200 with Toshiba 8x ATAPI
cdrom. This cdrom was configured as a _slave_ in my _secondary_ ide
controller. I also have a HDD in _primary controller.

I was trying with "linux hdb=cdrom" in the lilo prompt but I saw no
cdrom lights and then tried "linux hdd=cdrom" with the hope that if hda
is my primary controller and master then hdd should be secondary
controller and slave.

It worked.

Thanks

I'm having the same problem too!

One slight difference is that when I installed Slack 3.0 using the boot
and root disks, the bootup detected my second controller and Mitsumi
FX400 ATAPI CDROM. (One weird thing is that I got a bunch of timeouts
on /dev/hdc and I had to keep opening and closing the CD tray for it to
get re-recognized.)

BUT, once I installed Linux and rebooted, the controller, and
subsequently the CDROM, didn't get recognized.

I also tried hdc (and hdd) = cdrom from lilo, but no dice.

If anyone is interested, I'm appending /var/adm/messages to the end of
this message. Note how ide1 and IRQ 15 don't even show up.

Any ideas? Please Cc: replies directly to me.

Thanks,

Dave Egts

If you have problems with the CDROM in the secondary IDE channel (hdc or hde),
try what worked for me. I disconnected the master (hda) disk drive in IDE 1
(since it was dedicated to DOS/WINDOWS, jumpered the CDROM for master and
connected it to the 1st IDE channel as hda, then when I boot linux with
hda=cdrom, it saw the cdrom, and I installed to hdb (the 2nd drive in the
first IDE channel (drive D on Dos). After the installation I reconnected
the CDROM to the "proprietary controller" that Creative Labs bundles with
it's 8X-cdroms (it uses IRQ 10 (IDE channel 3?). When I start hacking the
cdrom drivers in Linux, I will attempt to fix these problems.

Apparently, the devices hcx thru hdx aren't done right. In /dev (I think)
there is a script executable called Makeidedev.1 or something like that.
Run it to set up the device files properly. Or look for you README.ide
file and it will give you the right instructions.

I have a Creative(aka Panasonic 563) 4X as slave on my second controller
port and the boot parameter 'hdd=cdrom' works fine. Of course, a valid
CD has to be inthere during boot.
