I put through this question to ECS, but who knows when, if ever, I will receive a response. The manual refers to what will come up when using the mobo CD with Windows 2000, but drivers on their site all say WinXP. It might be old boilerplate copy in the manual that was never changed. Don't want to buy the board and then have to go through the hassle of returning it. Thanks for any help.
I got one of the A740GM-M boards back in Nov. 09; I've been attempting (as i come across alternative or updated drivers) to run Windows 2000 on it, as It's my preferred OS.
Absolutely no luck so far; the integrated sound system is the the only thing that actually causes a bluescreen until it's disabled, but the southbridge drivers simply will not work; No USB support, no integrated video support, no integrated LAN. I suspect a add-on PCI-X Nvidia card might work, but I don't have one available to try.
Windows XP or newer, Debian, work perfectly. actually a really powerful board.
