Hi,\nAccording to msi's website, specifically;\n[URL]http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID=[/URL]\n27\n\nThis motherboard supports athlon processors up to XP2000. I have just\ninstalled an athlon XP1800\nand D-LED is giving me four red leds. The machine boots/runs fine when\nfitted with a 750MHz Duron.\nI have updated the bios to version 1.9 but still no dice. Does/should this\nversion of this board (1.0 not 1.0A)\nrun an athlon XP? The processor is OK, I reinstalled it in its existing\nmachine to post this message. TIA\n\nGeoff\n\n300W codegen PSU\n512MB crucial memory as two 256MB modules slot 1+2 ( compatible with the\nboard according to [URL]http://www.crucial.com[/URL] )\nAthlon XP1800 (hopefully!)\n2 X 40GB seagate barracudas.
