Good, I'm in need of reasureance (I have a badly mastered CDR of 5.1 that
I can't get the installer to talk to ;).

Ok, you should be able to just load the tape module (called st), if you
have kerneld running (or kmod in later 2.1.x kernels) just trying to use
the tape should get it loaded. Throw a tape in and do a
"mt -f /dev/st0 status", and you should get some status info from it.
Alternitavly you can load the tape module by hand with a "modprobe st".

The kernel source rpm should be called kernel-source-2.0.34-0.6.i386.rpm,
which has the source at /usr/src/linux-2.0.34, if you just make a symlink
with "ln -s linux-2.0.34 linux" everything will be fine.

Fine any kernel version should be ok, tho devlopment ones may cause
slight problems with some utils (sais he running 2.1.103 ;).

Ok, it sais that the kernel when uncompressed is too big (it's got to
be loaded and decompressed in real mode into that annoying 640k memory
limit you thought you had escaped ;).
The fix is to either use modules to reduce the kernels size, or make a
bzImage instead, which allows the switch to protected mode to be done
earlier in the boot sequence.
If you run a "make bzImage" you will get a bzImage in linux/arch/i386/boot/
which the version of lilo you have sould be able to boot (RH5.0's version
does, so... ;).
