Can anyone confirm that there is a driver > to support this card? The DC395 and 315 boards are based on Tekram's S1040 chip, not the Symbios/LSI chips like the 390 boards. The S1040 is only an Ultra-capable chip, so in the case of the 395UW, you'll only get 40MB/sec performance out of it. Also, the chip needs multiple interrupts per transaction, so it isn't as efficient as the Symbios/LSI chips. That said, Tekram has written a FreeBSD/CAM driver for the 395/315 boards, and I commend them for it. It looks like they have a driver for FreeBSD 4.0 on their ftp site here: ftp://ftp.tekram.com/SCSI/3X5/FreeBSD/FreeBSD400 The driver hasn't been integrated into FreeBSD because no one with the hardware, time, ability and motivation has stepped forward to do it.
