No, not FAT, he needs a PReP boot partition (And it needs to be the first
partition in the disk) in order to boot... the RS/6K is able to load
compressed and uncompressed images as long as they're gzipped and not
bzipped.

The faq is a bit outdated, Dan (Burcaw) has a page in the terraplex servers
outlining the real procedures to run Linux from an RS/6K

Right, but always keep a copy of the image you compile in the boot directory
(Good housekeeping :)

The Symbios driver is b0rked since 2.2.16 for some bizarre reason, I use
2.2.15 from the YDL CD and patch it accordingly. In my experience 2.4.0
works better than 2.2.1x with the RS hardware if and only if you get it to
boot. If he gets that far it means framebuffer is working, CHRP IDE chipset
is working (Or not compiled) and the Symbios driver has started
transferring, the problem might be the buggy Sym53C8x driver or the built in
ethernet controller. If he has an F50 it might be SMP support, if he has a
B50 most probably is the SCSI card. If someone is interested I can send you
guys my .config for the 2.2.15 kernel (Works+IPforwarding+Proxy+Other stuff)
over the mail (Outside the list to minimize traffic)
In any case once it works, Linux on the RS/6K beats the heck out of any x86
processor :)
