To make it more clear, it is the disk address packet which I need to
transfer to protected mode memory. The LBA number in the disk address
packet needs to increase by one after each IO. I do the increment in
conventional memory, and then transfer the packet to DOS using
dosmemput. After the IO is done, I read back to status of the IO by
doing a dosmemget. Can there be a way to eliminate the data copying
altogether? And be able to read the status of the IO as well.

Thanks,
Ahmad
