Mitsumi CD-ROM on Slackware 2.0

Mitsumi CD-ROM on Slackware 2.0

Post by Kenneth Bro » Mon, 05 Sep 1994 12:52:36



I am trying to install Slackware 2.0 (kernel 1.0.9) on my new system, with a
Mitsumi CD-ROM.  Once the system is booted, I am unable to access "/dev/mcd"
which is supposed to be the Mitsumi drive.  I get a "No such device" error.

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.)

Mitsumi CD-ROM on Slackware 2.0

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 just installed Slackware 2.0 last night.  I have a Mitsumi CD drive on IRQ
10 and a Adaptec on IRQ 11.

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?

1. Slackware 2.0 Mitsumi CD-ROM & Adaptec SCSI controllers

 Hi all,

  This maybe an old issue but I just bought the Walnut Creek Toolkit for
  Linux 2 CD-ROM distribution containing Slackware 2.0 Linux.   I have a
  486DX2/66 VLB system with an Adaptec 1540 2 SCSI drives and a Mitsumi
  2x CD-ROM.  No IDE drives.   The package comes with a few kernels
  configured for different hardware configs.   I picked the SCSI/Mitsumi
  CD-ROM kernel.

  The problem I'm having is that no matter what the IRQ for the Mitsumi is
  set up as, the kernel want's it to be IRQ11.  The default (and only
  working IRQ) for the Adaptec is IRQ11.   If I set the Adaptec at a
  different IRQ than 11, the kernel reports the correct IRQ that I've
  set it to but hangs probing the SCSI bus.  When the kernel see's the
  Mitsumi board it assigns IRQ11 to it.   If the Adaptec is at 11, well
  you get the picture.   The only way to get the kernel to come up with
  the Adaptec and drives recognized is to remove the Mitsumi board (or
  change the base address which causes the kernel not to recognize the
  board).

  Is there any way to get this thing to come up with both units recognized
  and in a way that I can load linux off of the CD-ROM?

  Hardware:
    Intel 486DX2/66
    VLB/ISA MB AMI BIOS (HiNT chip set ?)
    16MEG RAM, 256K External Cache

    Adaptec 1540 SCSI w/ 2 SCSI drives (/dev/sda1=180meg and /dev/sdb1=1.1gig)
    IDE Cntrl. (w/ HD disabled) as a floppy controller (1.44)
    Mitsumi 2x CD-ROM with Prop. Controller.
    Sound Blaster 16
    3C503 Ethernet Board
    2 Serial 1 Parallel 1 Game port board
    VLB Genoa SVGA card w/ 1meg RAM (uses National Semiconductor Chip ?)
    15" SVGA Monitor (1024x768 NI).

  Thanks in Advance!
