Yes, but support for the backpack has been evolving over the last couple
of years.  The 163550 is an older model - which was not originally supported
but is now supported in the most recent Linux drivers.  Unfortunately,
RedHat's boot disk does not have the current driver on it.   The first
thing for you to do is to get

That's a boot disk for 5.0.  It has the latest driver on it.  Please
make a floppy from it and boot it with your backpack attached and the
5.1 CD in the drive.  You probably won't be able to finish the installation
with that disk, but it will confirm whether your drive is going to work
if we make a real 5.1 boot disk.

When asked for parameters, just enter


Then check the <ALT-F4> screen for the autoprobe messages ...

1. Help: Redhat 5.0 & Backpack bantam CDROM

Help - I have a Micro Solutions Backpack Bantam CDROM drive, and I can't see
it. How do I insmod it, or is it supported? I have tried insmod bpcd and
have added the parameters bp_base=0x378 and bp_mode=0, 1 and 2.

I have also tried bp_debug=1 to try to identify what's wrong, but I can only
see that it either a)can't see the devide at 378, or b) it only seems to use
mode 1.

My question really comes down to whether or not RedHat supports EPP or ECP
connections, and if the driver has a bug (!) where it only supports mode 1.
