I must admit that consumers rarely ask to go through the bios setup before buying a computer mail order! >Complain at those guys who've been selling That Crap (tm). I merely asked what it meant. I believe I have discovered that there are flags on the wd0c controller line in the config file that allow you to specify multi sector transfers. I have put my bios in PIO 3 mode and set the flags to 3 and things seem to be working fine. I haven't done any disk performance tests to determine if it is indeed transferring in a faster mode. >(I could provide you with realistic papers that have been calling it >`crap' actually before it hit the market in the way it does now. >Alas, i guess you won't be able reading them, they're in German.) I'll assume you're just tired and not rude. Thanks for the response, Tom
