Very Computer

I have another system with a Sony CDU-535 drive, and was told that the
distribution had the wrong major device number for the sony drive.  Once I
changed it to the proper numbers, I successfully installed Linux on that
system.  Does anyone know if the Mitsumi drive also has the wrong device
number, and what it should be?  Or does anyone know what I might be doing
wrong on this system?

:       The problem may be that the kernel you are using has the incorrect port,
: IRQ, and DMA settings for your CD-ROM player. Check the file
/usr/src/linux/include/linux/mcd.h to see if it contains the proper values for
your setup. If not, change them and recompile the kernel. This worked on my
system.

Thanks for the info.  (Of course, I couldn't reconfigure the driver until I
had the system installed.)  I was able to install by copying the CD-ROM onto
my DOS partition and installing from there.  Then I was able to reconfigure
the driver.

Everything is working fine now.

BTW:  If anyone else out there has a Mitsumi CD-ROM drive, the default
configuration uses I/O address 0x300, and IRQ 10.  (My drive came with
address 0x310.)

Just a thought on this. If you already have Linux running with you /dev/mcd
compiled correctly, you simply can copy your kernel to the root disk of
Slackware. (Say using the commands "mount /dev/fd0 /mnt", "cp /vmlinuz /mnt")

Now it boots a kernel which recognizes you hardware correctly. It worked
for me nicely.

I used the root/boot images and made no changes to them.  When the kernel
booted up, it found my Mitsumi on IRQ 11.  And when it went to load the SCSI
driver, it couldn't cause IRQ 11 was already in use.

The install went fine (damn nice install program).  I then replaced the kernel
on the hard drive with my original kernel I've fixed up for my machine,
rebooted and it all went fine.

Wierd.  Why would it find it  (and use it) on the wrong IRQ?
