I got LinuxBIOS booted on the Tyan S2462 this morning, using:
LinuxBIOS CVS + compile fixes CONFIG_COMPRESS=0 (haven't tested CONFIG_COMPRESS=1 yet) etherboot-5.0.7 3c9805.ebi mkelfImage-1.18 Linux-2.4.20-rc1 RedHat 8 (gcc-3.2 and 2.13.*)
Lack of understanding + outdated tools (downloaded a while back) complicated things enormously. It helps if one Read[s] The Fine Source.
HOWTO for Dummies (I'm overqualified :-)) to follow.
Thanks.
