When I started coordinating the FAQ, all I had was an Ultrastor24F. It worked OK, but you had to configure it as an IDE/ESDI controller. The throughput was very respectable and it was a very reliable card. Of course, since it wasn't really a SCSI card at that point, stuff like CD-ROM and tape were pretty much out of the question. :-( I traded an Adaptec 1542A card for it, after tht card was supported, and I was never disappointed except that I had to remove 16Meg of main memory. The upside was that CD-ROM and tape were possible. I wrote to Ultrastor and got the programming specs for the Ultrastor 24F. I told them that I was developing a controller interface for a public domain Unix OS, and the source needed to be releasable. Even though I signed an NDA, they said that it was not a problem. I guess as long as you are up front with them, it's OK with them. From what I could see of the docs (and can discuss) the catch was that the 34F code didn't interact correctly with the card number address (working without a net here). It was an EISA only sort of problem. >>Is this true? > To use the ultrastor 24F in your EISA machine, configure the card to the specifications in your documentation for 'Booting SCO with the default kernel.'

I think the problem you are going to find is the problem you identify in your second sentence above. I don't know that anyone has a universal understanding the SCSI cards out there. THere is a section in the FAQ reserved for just such a list. I will gladly put whatever list gets put together in there. Of course, you are NUTZ if you think I'M going to do it :-)... -- TSgt Dave Burgess NCOIC Applications Programming Branch US Strategic Command, Offutt AFB, NE burgessd@j64.stratcom.af.mil
