I recently installed Red Hat 7 on an old computer I hadn't gotten around to
throwing out. It installed OK from CD, but after that I couldn't get to the
CD player. I tried a mount command:

mount -r -t iso9660 /dev/cdrom /mnt/cdrom

but get the message

mount: /dev/cdrom is not a valid block device

(And mount ... /dev/hdb ... gets the same error.)

The CD drive is connected to the same ribbon cable as my hard disk, but is
not recognized by my system bios, which shows only a primary master. When I
was running Windows 98, Windows added the CD player to the Windows system
hardware list, and it showed up in Windows Explorer as the D disk. (If it
matters, this computer is old enough to have the old bus architecture that
manufacturers quit using about 1997.)

Any ideas whether Linux can get to this CD player? It seems odd that the
Linux installer can operate the CD player, but Linux itself can't!

Thanks,
Bill

And dmesg | more tells you that the CD is recognized?

Stop trying to mount an audio CD, it has no filesystem and does not
"mount" from Win<anything> either. You "play" it with a player, a really
simple concept.

As I said, I used the CD player for the Linux installation CD. Obviously
I'm talking about data CDs, not music CDs. Take a look at Davide Bianchi's
reply if you want to learn how to be helpful.

Thanks for the info. demsg said:

hdb: ATAPI CDROM ATAPI CD/DVD-ROM drive
hdb: driver not present

When I tried to install Linux 8, the install procedure asked what driver to
use for the CD player, and gave a list of choices -- and I even think an
ATAPI was on the list. I tried to load several of them, but they all ended
up saying "driver not loaded". I gave up on Linux 8 and went back to Linux
7, which didn't ask for a driver.

I had to boot the Linux installation from floppy. It occurs to me that the
device drivers are probably in that dos... directory on the installation CD,
and I needed to copy the device drivers onto the installation boot floppy.
I'd try that now, but I borrowed the Linux CDs from the public library; I've
already returned them and someone else has checked them out.

If those drivers are available for download somewhere on the Internet (along
with instructions for how to install a CD driver from a floppy!), please let
me know. Meanwhile, I'll put myself on the waiting list at the library.

Thanks a bunch,
Bill

Try using the command as root from the console or xterm session:
/sbin/depmod -ae

So, he knows that there is a CD, but he doesn't know which.

I think you have to download the source of the kernel (unless you
already installed them in /usr/src/linux) and then compile
the driver from the kernel. IIRC there is an 'Old IDE/atapi support'
option in the kernel.

depmod returned no output.
However... dmesg indicated that there is no device driver for /dev/hdb...
see my reply to Davide Bianchi.

Thanks for giving me an idea to try out.

You might try booting the install diskette and switching to another
console using <alt><Fn> (Fn => F2, F3, F4 or ???) Some install
programs have another console available in which you can type
commands. Then type "lsmod" and try to figure out whuich module is
the one that works with your CDROM. Once you know that, you can type
"modprobe <name>" (as root) when you have the regular install running
and it should load the correct driver. Most likely the module is
available and you just need to figure out which one it is. If that
works, then you need to figure out how to get it to load automagically
so you don't have to 'modprobe' every time you want to use the CDROM.

HTH,
