AOpen's AX6BC is a standard single CPU 440BX mainboard with 5 PCI slots, 2 ISA slots, and 3 DIMM module slots. As with the newest mainboard offerings from rival Abit, AOpen's AX6BC is equipped with a simple jumperless BIOS setting program which eases the selection of various CPU and FSB speeds (particularly for the overclocker). Unlike Abit's "Soft-Menu II" however, the AX6BC offers no ability to adjust or change the voltage level of the CPU. This shortcoming isn't as important as it used to be, as the .25 micron Deschutes core Pentium 2s (P2-333, 350, 400, 450) usually need no voltage increases to achieve basic overclocked MHz levels.
In addition to the wonderful jumperless setup, the AX6BC utilizes a brand new BIOS from AOpen (10-21-98) which allows for more detailed control over SDRAM and PCI configurations than most 440BX boards on the market.

Lots of good stuff there, including the addition of Norton's Anti-Virus software (a good program to have if you spend as much time on the net as we do) for free.
AOpen seems to have really bent over backward to provide the foundation of a great mainboard in the AX6BC, but how well does it all work in the real world?
