I'm trying to install SCO 3.2.2 on an Everex 486/33 with an Everex 8110 SCSI host adapter and Seagate ST41200N (Wren 7). When I try to initialize the disk, I get the error message WARNING: No configuration information for Sdsk unit 0. I can't find any info in the manual about what the problem might be. Will SCO not work with the 8110, or is there something that I'm missing? Mike

I don't really think the 8110 is supported by SCO. The only controller supported without problems (yes, even the WD-7000FASST II makes problems) is the Adaptec 1542B and all [ really ] compatible boards. Regards Ralf. -- | Ralf U.

Although SCO supports the Adaptec 154x SCSI host adapter, it has such a poorly implemented device driver that your disk performance will suffer. SCO's Adaptec driver has no disk request sorting, does not do any effective scatter/gatter, and is in many other ways quite inefficient. We have full SCO source license at Altos and therefore I know its limitations. Sorry if I may have pissed anyone off by stating this, but this is reality. By contrast, Altos' own highly-optimized Adaptec driver has about a 10x performance advantage over SCO on disk intensive benchmarks. Of course, this is not all due to the Adaptec driver since Altos has also optimized the filesystem and buffer cache. The only way you can get the Altos driver is to have Altos UNIX, but then in order to get that you have to have bought an Altos machine. ALtos currently doesn't sell its UNIX release as a standalone product. -Ti -- /// Ti Kan /// Internet: ti@bazooka.altos.com ///// UUCP: ...!{uunet|sun|sco|apple|amdahl|pyramid}!altos!bazooka!ti /// vorsprung durch technik!
