Hi,

I would like to ask you about the floppy operation. At the Linux (boot.s)
there is a procedure kill_motor where we can see the following code of I/O
operation:

mov dx,#0x3f2
mov al,#0
outb

At the Minix OS there is, other that the previous, also the following:

andb 0x043F, #0xF0

My question is if to update the BIOS data area is something necessary.

     Thank you
