how to detect multimedia keys

I'm not sure my previous thread had a correct subject so I'm posting again. I know about not re-posting, but if nobody has a useful answer on this, soon it won't matter much ...

So ... I'm trying to build a "driver" for multimedia
keyboard capable of detecting multimedia keys.

If anyone has any idea on how to do this, please
answer. I need this because original driver performs
poorly (had to tweak few registry settings).

I tried with various MSDOS and Win-based progs,
best results so far were detection that media keys has been pressed but no scan-code (code 255 shows up constantly).

I know this can be done, I did it before on other computer platform and it is done on PC, under different OS (a rare variety of linux, but it is too much OT to explain it).

Scancode is a utility to find out the key scancodes using all three different methods to acquire a scancode. You can look into the keyborad buffer, use INT16 extended services or use INT16 normal services. Copyrighted freeware.
