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?
