As part of a strategy to protect my (commercial) application from
piracy, I want to write to, and verify from, the boot sector of
the original floppies.

How can this be done - any ideas ?
Has anyone else attempted this ?

Steve.

Oh dear - the things we do to stop priracy!

There are DOS Interrupts to write to a specified sector (13h function 3)
but I have never tried!
