Direct access to floppy?

[William W. Plummer]

I have VC++ 6.0 on Win2Kp and want to write a program to access specific
sectors on a floppy disk. This used to be straight forward using MASM
and calls to the BIOS. Do I need the Windows DDK to get the right
libraries? How do I get around the protection that Windows has that
prevents direct access to hardware?

I think you can't to this in Windows 2000. You will have to write a VM DLL
for it whose code runs in ring 0.

Hello

You can get the excellent tutorial on writing these DLL's at
www.win32asm.cjb.net. -> tutorials -> vxd tutorials.
But remember these are for Assembly language, but what matters is API
function calls.
I think you can easily port them to you language , by understanding the
concepts.
