I have an A7M266 which is still at the BIOS from when I bought it (last August). I have a 1.4GHz Thunderbird, but am thinking about dropping an XP1800+ into it. Apparently, the newer BIOS's add support for the XP line, so I thought I'd update. But I've had problems with Asus BIOS in the past not being very stable. Does anyone here use an A7M266 with version 1007? If so, is it stable? Or are/were there any problems after you flashed it? Thanks.
