Hi,

I tried to hook up two harddisks to an atari running ST 1.5.0. I recompiled
the kernel with NR_DRIVES (in <minix/config.h>) set to 3, booted the new
system, created the devices, and it all works fine. The two drives are each on
one controller, so the situation is:

	controller 0, lun 0:	first disk,
	controller 0, lun 1:	**no disk connected**
	controller 1, lun 0:	second disk,
	controller 1, lun 1:	**no disk connected**

I jumpered the second disk to 'Target #1 == ACSI-id #1'.

Remember to use major device number 3, and to built the minor device number
like:
	ccccdppp	c = controller number
			d = disk number (0 or 1 -> max. 2 disks/controller!)
			p = partition number (see stwini.c)

I also dived deeply into stwini, learned how to program the DMA and the HDC,
and I couldn't find any errors. So I guess making the new devices and
recompiling the kernel should do...

Good luck,
