AMD 2600 , running at 266 1.5ghz -Asus A7v8x-mx - Bios 1008.002 - 512 MB DDR 333- samsung 120gb - techcom 350Watts . When connected to the primary IDE on motherboard the hdd disappears after some usage while the DVD-Combo was detected fine . this was withing windows and bios . initially thought HDD prob and did disk fitness test . It passed . Swapped combo and hdd . combo went missing after some time in Win2k and XP . got device removed error in event viewer and when checked in . All cables were checked rechecked with all possible combination of 40/80 pin cables and all possible jumper settings . Weird part - fixed an old cdrom as master from old pc on ide 1 and it all seems to work fine now without any hitch . Is there a possible problem with ide controller on motherboard . can there be problem only with one ide controller ? Bios updates doesnt seem to work at all too . Current setting IDE 1 master - cdrom IDE 1 Slave - Combo IDE 2 master - none IDE 2 slave - HDD Has anyone been able to solve the problem with restart " restarts after 10 seconds during cold boot " with this motherboard other than downgrading bios to 1005 ?
