I have a problem here with my old pc (pentium1). i dismantled the whole pc and added a hard disk and some extra ram salvaged from my father's dad pc and reassembled it. After i have checked for correct jumper settings and cable connections, i started the PC. Everything turn out to be fine, the two hdd drives and cdrom - drive were detected....until a message "Failed Disk(s) (40)" appeared on the screen. Anyone has a clue about this peculiar quote?
