You can read Wikipedia on EDID (like I just did!), but practically it means the driver has to choose some default resolution and you may have to force the resolution you want manually. I don't know when the EDID approach was adopted, but I also have some monitors too old to play the game.

It has only SATA ports. There are ways to convert a PATA drive to SATA interface, but it would probably make more sense to get a small SATA drive. Fortunately, they don't cost any more than the CPU you don't have to buy because it's already on the board. You'll need a stick or 2 of DDR2 memory, either 800MHz or 667MHz. Intel tech specs at http://downloadmirror.intel.com/18357/eng/D510MO_TechProdSpec.pdf By the way, I keep calling it a D510M0 (that's M-zero) but, as reflected in this URL, apparently it's a D510MO (M-Oh). Obviously, there's a lot to like about these new, small, cool, quiet integrated boards, but I've got this feeling you can coax your current hardware into reasonable performance. I tried the new LiveCD on my aging Dell desktop (P4 2.6GHz with external GeForce5200), got very good latency results, and didn't notice a slowdown in the simulations I tried. Keep on truckin' !
