>Description:
	Two BusLogic BT-958 controllers, each with 4 Seagate ST34371 wide
	drives. Reads go at ~7MB/s on the outer zones. Writes go no faster
	than 60KB/s. I'm not kidding.

	System: 512MB primary memory 200Mhz PPro SuperMicro P6NDH motherboard.
	BusLogics on secondary PCI bus.

	Workaround was to put an Adaptec 3940 in place. Drives worked fine.
