Dear Allison,
   
   I'm not arguing about commercial software. Everyone chooses for
himself/herself whether he/she wants software that's costly, backwards, but
company-supported or software that's free, progressive, but self-supported.

   I strongly believe that it IS the same port and that the DMA differences
could be handled at a lower (ka<xxx>.c) level as they are for the HDC9224
which exists on both KA410 and some KA42 systems but is certainly (I'm 99%
sure) supported by the same driver on both. I will know for sure when I
read the relevant technical manuals and play with Ultrix.

   Not sure about this, will see.

   I'll tell you as soon as I hear back from SCO.

   Is that a SCSI disk? How do you have it configured in Ultrix? Did you
write your own driver, use some DEC-confidential code, or simply play with
the kernel config file?
