I had a shuttle box quad core amd running Ubuntu 9.04 64 bit. Anyway it was always losing it's bios settings so I presumed the battery was flat.

Since the shuttle had always been a little twitchy apic had to be disabled etc to get thing to boot into Linux. I decided to move the install over to another Shuttle XPC SG31G2 V1 model which was running Windows 7 without any problems.

Got it running surprisingly easy as I expected a full re-install jobby but I quickly reconfigured it and it was loading into X properly.

However the bios settings also get reset on power off. All seems very strange to me.

Any ideas bar booting of a live cd and see if the same happens???

What BIOS settings are you using that need saving?

Are you following the bios program's save method ?

When it powers off the bios is basically reset and I have to go back in load performance defaults and save and exit.
It's okay until next time it's powered off.
Anyway now just trying Ubuntu 10.4 LTS just out of interest. If it does the same perhaps it's two bios batteries I need.
