get the drivers from http://promise.com and read carefully readme.txt
do exactly what they write in readme.txt until you experience first problems (they will come soon enough ;-)
You will find out that suse setup found 3 hard disks: /dev/hda, /dev/hde and /dev/sda or similar. This is wrong. you should only see /dev/sda.
ignore this fact and install everything into /dev/sda
in boot options (suse setup) define user boot loader (don't use lilo)
make your choices on software etc, setup keyboard, setup time, just the normal stuff.
After copying all packages onto your harddrive you may experience setup saying: cannot write mbr
now you have to leave the readme.txt path. Ignore this error message and continue. You will fix that later.
After completeing the setup just as normal, you root into the shell and mount your floppy and start sh setup-ft
check whether the kernel images are in /boot. if they are not, /etc/lilo.conf will be missing too. install them from package k_deflt
if the kernel images are there, check lilo.conf. Check the append lines for syntax errors (wrong tokens). Check the disk = parameter. if needed change it to /dev/sda
install mbr to /dev/sda using lilo command (see man lilo how to do it)
using lilo command define the proper boot device (/dev/sda)
reboot - it should work now.
I didn't have to install k_deflt package in my last attempt. The way to solve these problems may be other than what I described above.
