The first consumer-oriented Pentium M motherboards were released late last year by AOpen and DFI. (Editor's Note: And both boards were reviewed thoroughly by RH.) Both were based on the Intel 855G/ICH4 chipset, which is stable and mature but doesn't come with the latest features that enthusiasts expect on a brand new board. The rather high price point of these boards only served to exacerbate this issue.

AOpen was not content to sit back and see how well its initial Pentium M offering did in the marketplace. They quickly followed up with a new board, the i915GMm-HFS, based on the new 915G/ICH6 chipset. Included on this board are features like PCIe x16, DDR2, SATA300, HD Audio and a 533MHz FSB among others. The integrated graphics includes not only the typical analog VGA out, but DVI and HDTV outputs as well. I doubt that anyone will be complaining about the lack of features on this iteration of a Pentium M board!

Luckily for SPCR, AOpen was kind enough to send us one of these brand new boards to play with and we've been testing it out for the past few weeks. Today's review will give a bit of an overview of our impressions.

AOpen i915GMm-HSF. Unusual layout for an Intel board seems to emulate BTX.

First off, here's a chart comparing the features of the AOpen i855 and i915 boards:
