I was trying to upgrade BIOS because the DDR module i bought crashes Windows XP with BSODS, it works elsewhere. Besides that i wanted just to upgrade

Thanks for proposal of commercial upgrade guys, but I rather gather money for S939 platform (assembled by ME using KNOWN elements that WERE NOT PRODUCED BY CHAINTECH) or wait few months to get fresh and juicy Intel Conroe
Thanks WIMSBIOS crew and good luck!
