Incorrect cable identification? 1/ PCchips (SiS) P///-800 mobo, Pioneer DVD117, *40* wire cable, the dvd is configured for UDMA66 (partially works, unreliable). 2/ Various socket 7 mobo, PCI card with CMD0649 chip, Maxtor D740X-6L HDD (probably others also), *40* wire cable, hdd is configured for UDMA100 (doesn't work). (I have probably seen this on other hw combinations also.) "atacontrol" can be used to reconfigure a dvd after booting. The worse problem is hdd, trying to boot install media and do an install. >How-To-Repeat: Same hw? >Fix: >Release-Note: >Audit-Trail: >Unformatted:
