The stores that sell the drives will frequently throw in a noname IDE controller for free. They might throw in an ST01 for free, too, if they knew what one is and had one :-) BTW, an ST01 works OK, and can do 500-700KB/sec. As can IDE controllers and drives. Good for the money. For the money, I still like a free Seagate 20MB drive (ST225) and a free WD1003. It's enough to test 386bsd kernels, and the price is right. It really does help to have one machine to develop and another to test. It's a really good deal if you can find supported Ethernet interfaces for $5 - $10 at liquidators, too. >Most SCSI controllers *do* a bit more than most IDE controllers, so you aren't >really comparing apples and apples.

Please send this information to Mike for summary! Terry volunteers me to collect information about drives and controllers that work with 386bsd as punishment for my disagreement with his clearly bizarre contention that expensive SCSI systems are better than Yugos with blown head gaskets. I'll do it. If you send me a quick e-mail with the controller type and brand (noname ok), the drive size and model if known, in a few days I'll summarize. It might be nice to include CPU type, speed, and BIOS if known. -- Mike Murphy mrm@Sceard.COM ucsd!sceard!mrm +1 619 598 5874
