problem recognizing Mitsumi cd-rom drive

Post by Timothy M. Renic » Thu, 11 Jan 1996 04:00:00



Hello everybody,

I am trying to set up my first Linux system.  I put a Mitsumi cd-rom drive into a computer.  
After loading the boot and root disks, I noticed that linux is looking at irq 10 for the cd-rom
drive.  It is located at irq 14.  Is there a command after loading the boot and root disks to
tell the system that the drive is at irq 14?  I have looked through a couple of books and the
cd-rom HOW TO from my InfoMagic cd-roms, but cannot find the answer

Thanks for any and all help,

-Timothy

If the IRQ is 14 it most likely uses the IDE interface, not the (proprietary)
mitsumi interface.  Use the ide/atapi cdrom driver.  I'm sure there is a
HOWTO, or at least a README, telling how to use it.

When the boot: prompt appears type 'ramdisk mcd=0x___,14'
Put the CD address in ___

1. linux, Mitsumi CD-ROM (& SB), & the TA CD-ROM - solved!

Finally!

As I posted recently, I got the TA CD-ROM, and found that the setup kernel
recognized the CD drive, but the installed one didn't. I had trouble with
the recompile, as well.

The answer is:
    in (I think it's) /etc/include/linux/drivers/blocks, there are *two*
        makefiles. One is named Makefile, the other Makefile.orig. When
        I diffed them, I discovered Makefile.orig *had* conditions for
        compiling the Mitsumi driver, the Soundblaster driver, and one
        other driver, and Makefile *didn't*. I renamed both, and reran
        the compile. No problems, using lilo (after the usual moving &
        /etc/lilo/install) I boot off my hard drive, I can mount the
        CD ROM, etc.

I am emailing TA this, as well.
