Re[2]: ** How to get physical drivenumber from logical drive letter **

Hello Rajesh,

The BIOS (and hence INT 13) knows nothing about drive letters or
files. It is DOS (or more generally, the OS) that provides the file
system and assigns the drive letters to physical drives/partitions.
I haven’t come across a service to map drive letters to physical
drives under DOS, but if there is one it is likely to be an INT 21
function.

That page that documents int 13 also has porno ads. Maybe it is not a safe
website. Be careful
