BIOS
The BIOS is generic AWARD fare and everything exciting, CPU and voltage wise, happens in the section labelled Miscellaneous.
As you can see, the BIOS offers CPU ratio adjustment, but it doesn't actually work in the shipping BIOS, or the latest BIOS available on Jetway's website. On the HEXUS 3.2ES processor, 12x was the boot multiplier no matter what was chosen in the BIOS. We saw similar issues with early Prescott samples on other boards, which were eventually rectified with a new BIOS, so that should be the case here too.
2.8V Vdimm, as shown in the above picture, is the maximum available choice, helping stubborn modules to possibly run at tighter latencies.
However the latency manipulation section of the BIOS was broken too.
You can see manually chosen 2-2-2-8, 2T settings in the BIOS, with 8 being the lowest possible selection for Tras. That never gets applied however and 5 was the set Tras selection every single time, no matter what was chosen (8 and 12 are the only choices). The SPD timings for the DIMMs used isn't 2-2-2-5 at DDR400, so god knows what the BIOS is actually doing there and it's definitely something else that needs to be fixed.
You get up to 255MHz front side bus frequency in the BIOS, but PT800 doesn't lock PCI. It's not an overclockers board, be under no illusions.
The usual AWARD health monitoring is present too, with simple overheat protection and display of PC health at POST time.
