Erm, anyway. I have my initial success in getting RedBoot to run from
LinuxBIOS on the SiS630 in a 256k part. What I'm missing now is hard drive
support, although RedBoot's ide drivers should be completely polled, I'm
having trouble forcing the controller on.

There you will find:
romimage - 256K flash image for RedBoot running under LinuxBIOS
redboot.ebi - elf boot image to be attempted on other chipsets as well
fixedredboot.cap - minicom log of the boot up as it is now
redboot_LINUXBIOS.ecm - redboot config script
winfast.config - linuxbios config script
southbridge.c - my attempt at forcing the ide controllers on, as pulled
from tiara
Please take a look and if you're interested lend a hand. More information
about RedBoot can be obtained at http://sources.redhat.com/redboot .
