I have a couple of programming questions related to building a hard disk cache.

To build such a cache at the rwabs level, what is the cleanest to do it?
Intercepting all BIOS traps and looking for rwabs calls would be one way.

My MWC manual lists a variable named "hdv_rw" under System Variables.  This
variable is said to point to the hard disk read/write routine.  Does anybody
know what parameters the hard disk read/write routine expects when called?
Is this routine used by all calls to rwabs?
