The short and sweet is that I have a bunch of IBM X345 dual Xeon
machines. I installed a half dozen or so with RHL 8.0 and have them in
production. Then, on advice of IBM, I upgraded the BIOS. Now nothing
newer than 7.2 will boot from CD. IBM says this is not supported, and
you can't downgrade the BIOS because the new one is larger than the old.
IBM says 8.0 isn't supported on that hardware, and the downgrade path is
to replace the sysplanar with an old one (if available).
Anyone got a hint of a workaround? Boot from floppy? Anything?
As we enjoy great advantages from inventions of others, we should be
glad of an opportunity to serve others by any invention of ours; and
this we should do freely and generously.
