Here's one more data point:

My setup:

	25MHz 386
	DTC RLL controller (don't have model # handy)
	drive with 26 sectors, 5 heads, 1024 cylinders.
	Minix 1.1 with 1.3 upgrade from bugs.nosc.mil.

Configuration that caused me grief:

	Disk initially partitioned with DOS 3.30 fdisk.
	No disk-geometry changes made to Minix fdisk and fsck.
	No changes in at_wini.c.

Configuration that is currently working:

	Disk initially partitioned with DOS 3.10 fdisk.
	Fdisk and fsck patched for 26 sectors and 5 heads.
	No changes in at_wini.c.

I had *lots* of trouble when I was using the fdisk from DOS 3.30.
I fixed the Minix fdisk and switched to DOS 3.10 at the same time,
so I'm not sure if 3.30 was really part of the problem.  I now
have a 32Mb Minix partition that's been exercised pretty severely.
The stock 1.3d at_wini.c seems to be working fine for me.

Al, thanks for the suggestion to rename controller_busy.  I'll use
it if I need to re-apply Marty's patch before 1.4b appears.
