The small one looks like an IDE controller with 2 interfaces, and the
big one looks like an old I/O board with floppy and IDE interfaces.
Either could be used in principle, but they'll be quite slow and
you'll need to reconfig the jumpers which may be difficult without
docs. I'd recommend buying a modern PCI IDE card from somebody like
Promise. That will 'just work'. Or get rid of the Zip drive :-)

I don't use Redhat and I don't use grub. However, the principles are
the same for all distros and boot loaders. When you install a boot
loader, it reads info in a config file somewhere, uses this to find
the physical location of the boot kernel, and stores this in the HD
master boot record. If the kernel is then moved the info in the MBR
will be wrong, and that's why you need to rewrite it. Once you've
booted the new root system somehow you probably just need to type
'grub' at the command line as root, but I'm guessing here. 'man grub'
should give you more info. Pretty easy stuff really.
There are lots of ways to boot the HD from a floppy. Try this. Format
a DOS bootable floppy, find a copy of loadlin.exe from your
installation CD and put it on the floppy, then copy your kernel to the
floppy (probably it's in /boot). Boot the floppy, then type 'loadlin
kernelname root=/dev/hda1 ro' (assuming your kernel is called
kernelname and your root linux partition is /dev/hda1). Your system
should boot normally.

It is in percentage terms, but there's still quite a lot of free gigs.
Can you organize a clearout?
