Actually I was thinking that if it is possible to perform all the Disk IO operations using the BIOS routines, then why can't we write a SINGLE disk driver that will work with all the kinds of disks.
Because that would be incredibly slow. You could only have one I/O request in flight at a time, and the system could not run other processes while I/O was being done.
So all this seems like a bad idea ... or should I say TOTALLY IMPOSSIBLE?
It might be possible, but it is still a very bad idea :) -- "Debugging is twice as hard as writing the code in the first place.
