When I first dipped into the 755A01's BIOS, I wasn't expecting much. After all, one only expects so much tweaking potential from a budget board. However, the 755A01's BIOS was a pleasant surprise.
With control over just about every memory timing option imaginable, the 755A01's starts out well. The board's memory tweaking options are similar to those offered by Abit's KV8-MAX3, which is an excellent lead to follow in the BIOS department.
The 755A01's tweaking options go deeper than just memory timings. The board's BIOS also exposes an asynchronous AGP/PCI clock that should keep peripherals in-spec when running on an overclocked CPU bus. The BIOS offers CPU bus speeds between 200 and 232MHz in 1MHz increments, so the async AGP/PCI clock should come in handy. However, the BIOS's total lack of voltage adjustment options ruins an otherwise hospitable overclocking environment. Foxconn plans to offer voltage adjustment options in future products, but it's unclear whether such functionality will make its way into a BIOS update for the 755A01.
Unfortunately, the 755A01's limited voltage options prevented me from getting my Athlon 64 3200+ running on a high enough CPU bus to test the board's async AGP/PCI clock. The board doesn't support CPU bus speeds below 200MHz, either, leaving me no way to verify that the async clock actually works.
The lack of voltage tweaking options aside, the 755A01's BIOS finishes on a positive note with a user-configurable shutdown temperature and temperature-controlled "smart fan". The smart fan is a particularly useful addition to the BIOS. In a perfect world, users would be able to set temperature thresholds and fan voltages for the smart fan, but Foxconn's implementation is a good start.
