Thanks! CPU is P4/2.9G, motherboard is 848P-M7 it's quite like 848P-M Deluxe: http://www.ecs.com.cn/ECSWebSite/Product/Product_Detail.aspx?CategoryID=1&DetailID=402&DetailName=Feature&MenuID=24&LanID=0 actually I might try to update BIOS from site above model numbers are the same, it's not recommended to update but it seems I have no other choice if motherboard become unusable, my trouble also ends I can't fully understand technical details you describe the point I want to repeat is the machine can run Windows XP and in memtest it's OK after configuration Linux fail here, (or does it?) -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
