This won't make any performance difference, but it will prevent possible
data corruption. The smaller value is correct, the 131072 number was an
error in an older version of the software.

The new graphical RDPrep is a whole lot smarter than the old software
was. It's not just a change to the RDB, though that's part of it. My
Hardframe is about two years old, and the software that came with it
sounds like what you've got. The new stuff is only about 6 months old.

The Hardframe DOES work with the Quantum 105 at 1:1 interleave, and the
combination is capable of 700KB/sec, it's what I've got running on my
A2500. But since your Hardframe software is so much older than mine,
some of the number don't compare too well. The first thing I'd do is get
the new software from Microbotics.

I don't think any of them are on Usenet, they do have an official
support conference on BIX though.
