Roughlky at a level between those 2 :
Linux : FDRAWCMD ioctl()
This lets you send an arbitrary set of command bytes to the FDC (allowing
you to do anything that the FDC is capable of), but it handles the DMA
controller (and aligning the buffer not across a 64K boundary) for you.
It's nice that it would do that for you.
FORMAT didn't even include code to do that right! If its buffer
straddled an absolute address divisable by 64K, it would fail, and blame
the diskette!
