Version 1.1.6 of the Flash BIOS is out and can be downloaded here. This version supports 64 bit operating systems.
The prior 1.1.3 release would not boot up an x64 Ubuntu live disk. Nice to have a 64 bit Core 2 Duo (what a lousy marketing name) and not be able to play with a 64 bit operating system. After I applied the update I loaded up my Ubuntu 6.06 x64 CD and booted into the live desktop. Cool, previously it would hang on just after unpacking the kernel.
This is probably done to support 64 bit Vista, but now I have the possibility of running a 64 bit Linux on my box just for fun.
