Hi, folks!

I am writing a TSR program and is now in a desparate need to find out
the best way to access hard disk. Since DOS function cannot be used in
TSR program, therefore I will have to use BIOS, which means I have to
do the sector/cluster/file calculation. Anybody know how I can find out
the sectore number of the first sector of the file area of a hard disk
without knowing its storage size in advance?

Any advice, reference, source code will be greatly appreciated!

Thanks in advance.
