No, don't use Diskreet. Use my Secure Drive. Beta now if you want it,
and release with source soon. Uses IDEACFB, protects a hd partition and
floppies, takes only 2K ram, and is very fast. Reasonably user-friendly.
You have to create a D: partition to use on a hard drive.

What's the CPU in a Courier? Is the hardware well enough documented
to hack something like this up? I once burned a rom for a friend's
courier, from a file which he had, to give it V.32 instead of just
HST which it previously had. Not sure where the file came from.
An SRAM also had to be installed.

The cpu is some DSP chip. I looked at it before but I dont remember
the maker/part no. off hand.
