These were good motherboards, but it's worth mentioning that some versions (think it was version 1.x) use a different clock generator, and so can't do the 1/4 PCI divider. I'm guessing that the boards they're selling aren't this older version, because the picture shows colored parallel port connector, while the older version had all black connectors.
Suprizingly, AOpen is still releasing new BIOS for these, last one was only a few months ago. I sold one of these a couple months ago, had a Celery 600@927 in it. There was some instability in mine at extremes of CPU core... Ran fine when i tried a Celery 1GHz@1GHz, but a Celery 733 o'c to 1185 wasn't at all stable, while that chip ran at same o'c speed fine in a newer Gigabyte/Via 694X board.
One minor annoyance is the floppy connector, is placed to the left and below the processor slot, making the only neat way to set it up being to use a really long floppy cable installed under the board before it's mounted in the case. Also, mine didn't have voltage adjustment either, but no biggie if you have a decent slotket.
While this is a fair deal, expecially for what looks to be a retal-packaged board, I'm wondering if it would be better than one of those Newegg refurbed socket 370 boards, which could work out to about the same price (or lower) when you consider the slotket cost for the AX6BC. Many of the cheapest Newegg refurbs are the Via 694X though, not the 694T... anyone know if the BX-Tualatin mod would work on other chipsets, using the same or different mod?
