Ok! So the only successful way to boot LinuxBIOS under any circumstances is to first boot factory BIOS, have it do something (possibly rewrite CMOS, possibly something else) and then reboot into LinuxBIOS without powering off the system?
Not at all. After the "reset," I can power down and restart (this is typical because I just hit the power switch, and linux shuts down). Often, I can come back later and it boots fine. Then, it suddenly starts having issues, and this is persistent until the "reset."
Ok, thanks for making that clear. Can you provide some timeframes? Ie. how much later "later" means, and how much time passes between "later" and "suddenly" ? :)
It _seems_ (but I haven't verified) to be exacerbated by having the machine off for a few hours/days.
If it works also when powering off between factory BIOS and LinuxBIOS, please leave the system powered off several hours up to a day and see it that works too.
Haha I hadn't read this paragraph when I wrote the above. It seems that long off times screws up LB.
The reason this may matter is that special configuration of chips performed by the factory BIOS may well stay around in chip registers even if power is cut for some time, while if the special config is in CMOS it will of course survive without power a lot longer.
