- QUESTION: Does anyone out there know of a good disk controller that
- would allow me to use Novell's CDC WREN III drives and have
- it boot DOS? Has anyone had any experience with the WD7000
- fast controller?
-
- ANSWER: The Adaptec 1540 is probably the most commonly used SCSI
- controller, which will boot DOS (due to the fact that has
- its own BIOS on board). It will support Wren drives with
- no problem. It can be used for duplexing in any channel
- setting from 0 to 4, and also performs multi-threaded IO
- through use of the SCSI disconnect feature, giving higher
- throughput than the DCB. Its only limitation is that it
- will not work with 16-bit LAN cards which use DMA, such as
- the 3C505 and NP600. So use the NE2000 instead.
-
- You need to be careful with the BIOS version on the WD7000
- FAST controller, or you will find COMPSURF failing.
