I have an IDE CD-ROM as the master and an Iomega 100MB ZIP IDE drive
as the slave on my second controller.  Before I installed the Zip
drive, the CD-ROM functioned correctly.  When I add the Zip drive,
I cannot access either device; disklabel -r and mount both hang, and
sometimes (well - usually) crash the OS.

Here is the DMESG output, and two attempts at a kernel configuration
file; neither work.  OS version is 2.2.1.

Can anyone advise me if these two devices can work on the same controller,
and if so, how I can do it?  I would appreciate parameters for disklabel
and newfs if I can get that far. Will an upgrade to 2.2.5 or even 3.0 fix 
the problem?

Both devices are seen correctly by Windows 95, which configured itself
automatically to my annoyance!  I can only use the Zip drive for backup by:

a) Writing a tar file to the MS-DOS file system
b) Opening the case and plugging in the Zip drive
c) Booting Win95 and copying the file.

Not a convenient or dignified procedure!
