I have used the Archive ``FasTape'' and ``Viper'' drives on
several SCO systems without any problems by setting the IRQ at 2
and declaring it to be 25 in ``mkdev tape''.  The Appropriate
responses to the prompts in ``mkdev tape'' are 1, 1, 25, 0200H.

I don't really understand the `logic' of Intel bus IRQs, but this
works fine where I've tried it.

Most of our systems are using Archive 150MB SCSI tapes
eliminating this problem entirely (except I had a bit of a bother
figuring out that I had to delete a tape and declare the scsi as
the default tape before I could use it under SCO UNIX 3.2v2).
