It works fine with tape > drives and an old 300 meg drive we tried. I'm using an DC390F, and it seems to be a very nice card. But I also had some problems with boots hanging, recently. (It always works if I press the RESET button on my box, though. It may be a problem with the NCR driver setting controller registers to values that the warm boot code in the cards BIOS does not expect ...) Their Web-Server (www.tekram.com) doesn't seem to offer any SCSI BIOS upgrades.

When does it hang: 1) After showing the brand/model of the drive ? 2) After finding all devices on the SCSI bus ? 3) After loading the FreeBSD kernel ? I just wondered whether you have a WIDE drive connected to the Tekram. This could cause problems, since an 8bit cable is used to connect a WIDE capable SCSI chip (the 53c875) and a WIDE capable drive, then ... (Although the 390U offers only an 8bit SCSI bus, it does in fact use a WIDE SCSI chip. The 390F is identical, but comes with a WIDE and an 8bit internal connectors and a WIDE external connector ...) > No, the question isn't really freebsd specific but there has been some > discussion of the Tekram here a while back... Yes, I added support for the Tekram Ultra-SCSI cards to the NCR driver. (More to come soon ... :) And I still think they are the best SCSI cards, especially taking their price into account. I'd like to get this sorted out as soon as possible, to have a chance to get this fxixed for 2.2R ... Regards, STefan
