It looks like Gigabyte's site only has thumbnails of those board pictures, but maybe my browser just isn't rendering it correctly (very likely).
I have some older, reasonably sized pictures of the GA-60XE and GA-60XET, but not the GA-60XE-1.
The component layout in the VRM area of the board matches a GA-60XE, not XET. But in the area between the northbridge and the AGP slot, it doesn't match the 6OXE anymore either.
There's a board in this article:
http://ixbtlabs.com/articles/i815moboroundupjun2k1/
whose picture is located here:
http://www.ixbt.com/mainboard/images/roundup- … e-ga-6oxe-1.jpg
and it looks like a perfect match, but check if you agree.
The article doesn't state clearly which version of the 6OXE is photographed. The only clue is the filename, which says "ga-6oxe-1.jpg".
Whatever you do, make sure you make a backup copy of the original BIOS before you flash it. That way you'll at least have a known good image to revert to. If it gets to that point you could get a chip made by somebody, or hotflash one yourself with another board (kind of tricky with PLCCs but possible). DualBIOS would have been nice, but at least they had the decency to give you a socket.
PS: I find it terribly perverse that Gigabyte used a letter "O" in these board names. That's what it seems to be from the font anyway.
