I got hold of the fix from Avante Guarde to make MS-DOS correctly read
the Atari SH204 hard disk under PC-Ditto.  Turns out that the boot
parameters in the HD are trashed after running the Atari utilities.
Here are correct values of the trashed parameters in logical sector 0
of each HD partition: (the trashy ones sure looked suspicious!)

		correct		trash

	NFATS	02		20
	MEDIA	F8		73
	SPT	0011		2E70
	NSIDES	0004		2C73
	NHID	0001		2076

(all in hex).  I also put F8 in the first sector of each copy of the FAT
in each partition, just in case (the fix program from A.G. does not do that).
They say you must fix it again after EACH TIME you run HDX or HINSTALL.
(Oh, BTW: where in the world am I supposed to get HINSTALL and SH204DVR.SYS,
the official (?) Atari HD boot stuff?  The SH204 I bought was shipped this
fall with only AHDI and HDX.  In contrast, Supra supplies a very nifty HD
sector editor.)
