Perstor Controller & Intel 386 Unix?

[Jim Heasley]

I recently came across an ad for a disk controller from a company
named PERSTOR which claims to essentially double the amount of
information that can be stored on most standard disks. From what I can
gather from their flyer, they provide a controller which uses a special
encoding scheme and a replacement BIOS for the computer that understands
the mapping between standard disk types and their encoding.  They claim
to be Sco Xenix, Interactive Unix, and OS/2 compatible.  

I'm running Intel's (formerly Bell Technology) Unix 3.2.2 and would be
very interested to make a major upgrade to my disk storage for the very
modest price of a new controller (it seems too good to be true, in fact).  
However, I'm a bit nervous about buying the controller and discovering
that it's not compatible with the Intel kernel. Has anyone out there all
ready tried this and if so with what results?
