BIOS

For enthusiasts, the options available within the BIOS can make a good board, a great one. The ability to manipulate frequencies, voltages, and fan control settings vary depending on the hardware and the amount of trust placed in the user's hands by the manufacturer. On mini-ITX boards, the options are usually very limited.


"Chipset Configuration."

We were surprised to find chipset and memory voltage options, though they can only be increased by small amounts.


"Performance Options."

Incredibly, Zotac also offers access to the front side bus, enabling users to over/underclock the Atom processor. There are also a variety of memory speed ratios and basic memory timings that can be selected manually.


"MCP Hardware Monitor."

The Hardware Monitor section is bare, displaying only the chipset temperature and two fan speeds. There are no fan control options in the BIOS.

The BIOS provides only a few tweaks, but honestly, it's a lot more than we were expecting. We noticed the Wake-on-USB feature that is missing on Zotac's GeForce 9300 motherboard is also absent on the IONITX.
