BIOS
The BIOS of the boards is based on the Award BIOS Phoenix version.
The major memory settings for the Foxconn's board are gathered in the overclocking section ("Fox Central Control Unit"), and those for the abit's - in the "Advanced Chipset Features" section:
The next important parameter that affects the performance is setting the memory operating frequency.
Now look at the system monitoring sections.
Both the motherboards display the current temperatures for the CPU and the system (the abit's model also detects the PWM temperature), as well as operating voltages. The boards determine the rotational speeds of the fans (abit's - three, Foxconn's - two) and offer the feature for adjusting the rotational speeds of the CPU fan depending on the CPU temperature. On the Foxconn's board, this technology is traditionally called Smart Fan, and on the abit's - FanEQ:
The boards grant the use access to all Intel's latest technologies.
On the Foxconn's board, the power-saving settings are gathered in a separate section ("Green System Mode")
The boards also allow adjusting the memory capacity allocated for the needs of the integrated graphic core.
Overclocking and stability
Before we move on to overclocking, let's look at the power converters. The PWM of abit I-G31 uses a 3-phase scheme, in which there are two 820 mkF, four 680 mkF, and four 1000 mkF capacitors. The PWM of the Foxconn's board also uses a 3-phase power scheme, in which there are six 820 mkF and three 330 mkF capacitors.
On the Foxconn's board, all the overclocking tools are gathered in the "Fox Central Control Unit" section:
There are not so many features but they are scattered among the numerous subsections.
As regards the abit's board, there aren't any overclocking tools in its BIOS at all.

| Multiplier adjustment |

| FSB adjustment |

within (200)333 MHz to 600 MHz (1 MHz) |
| Vcore adjustment |
- |
within -0.5 to +0.25V (0.0125V) |
| Vmem adjustment |
- |
within 0 to +0.3V (0.1V) |
| PCI-E adjustment |
- |
within 100 MHz to 255 MHz (1 MHz) |
However, the overclocking tools in the Foxconn's board have a poor practical effect. In particular, the maximum stable FSB speed = 350 MHz.
