Changed cdrom setting now linux won't recognize it

I had to change the io address of my mitsumi cdrom and now Linux will not
recognize it. I reconfigured the kernel but it still looks at the old address.
Can anyone help? Thanks in advance!



1. 'Toolkit for Linux' won't recognize CDROM

Hi, I'm new to Linux and trying to install it on my computer.  I bought
the 'Toolkit for Linux' from Walnut Creek.  When I used the scsi boot
disk and color144 root disk, it would recognize my SCSI controller (Pro
Audio Spectrum 16) but not the SCSI CDROM attached to it.  Finally, I
copied the A disks onto floppies and installed with those.  I thought
then I might be able to mount it.  As instructed in the CDROM-HOWTO, I ran:

mknod /dev/sr0 b 11 0
mount -r -t iso9660 /dev/sr0 /cdrom

but it said that /dev/sr0 was not a valid block device.  Doesn't the 'b'
in the mknod command create it as a block device?
Also, I read in another post to
cat /proc/devices
cat /proc/filesystems

to find out about my active devices, but I have neither of those files.
Any ideas?  I don't want to install ALL of the Linux stuff by disk!
