#How Map Log Drv to Phys

Unless your program can get into the innards of a DOS device driver and
figure out what it's doing, there is no standard way of determining which
physical disk a logical drive is mapped to. It's conceivable (tho not very
practical) that a driver could assign drive C to the first physical disk, D
to the second, E to the first, F to the second, etc…..
It's POSSIBLE that you could write a program that would figure this out by
first capturing the BIOS INT10 vector and then doing a disk read from each
drive….hmmmm….interesting idea….I wonder….
If I have some free time this week I'll take a peek at this…..

Errrr…
What I meant was BIOS INT13 vector, not 10. Sheesh….no wonder my
programs aren't working. I'm confusing the video and disk calls.

I remember seeing a table somewhere that has an entry for each drive
letter, and an explaination of it. Where could that have been??

Dunno. I'll look through the few books I've got and see what I find.
