Hello everyone,

Can anyone out there provide the BIOS files in order to re-flash mine here?
Im getting checksum errors every time, tried to change the battery, reset the BIOS through jumper setting, nothing worked.

Thanks!

It does updated the bios but the checksum error persists, even with new batteries on.
I think the CR2032 mod on the Dallas RTC chip went bad someway. I think I need to replace it with one of these new ones from Necroware.
