The 315 just uses that chip in a narrow configuration, and I think the 395 is an Ultra-Wide board. You can use it for FreeBSD, since Tekram has written a FreeBSD/CAM driver for it. (Tekram is to be commended for supporting FreeBSD! They also wrote their own AMD driver, which is in our tree, and their own NCR driver for FreeBSD.) You'll have to download the driver from Tekram's web or ftp site (not sure where it is), and compile a new kernel. The catch is that at least from the way the driver is written, it doesn't look like the chip has a SCSI phase engine, so it probably won't perform very well. (i.e. several interrupts per transaction) If you want a Tekram board, I would suggest one of their NCR/Symbios/LSI based boards. You can use those with the sym driver, and they will perform pretty well.
