I don't want XHDI NatFeats, but real disk access, like on real HW.

What I would like to have with Hatari, is kernel debug output to host
console, same as what happens with Aranym.

Giving "tty=nfcon" didn't help, but I don't know whether Linux
boot proceeded far enough to output anything.  That's actually
why I'm now trying to do real HD boot using bootsta.tos with
Aranym.

However, I'm having a bit of a problem with that.

I did small HD image with FAT using:
	tools/atari-hd-image.sh 16 16mb-linux.img LINUX disk/

When I boot with that using Hatari and EmuTOS 0.9.10:
	hatari --machine falcon --tos etos512k.img --ide-master 16mb-linux.img

Everything works fine, I see and can run bootstra.tos.

However, when I boot Aranym with same image and EmuTOS,
using this in Aranym config:
	[IDE0]
	Present = Yes
	IsCDROM = No
	ByteSwap = No
	ReadOnly = No
	Path = 16mb-linux.img
	Cylinders = 64
	Heads = 16
	SectorsPerTrack = 32
	ModelName = Master

And additional "-d D:./" option, EmuTOS (v0.9.10 release), shows
me just *empty* C: drive.

There are *no* warning messages to indicate any problems, either
with D: host dir mapping, or C: IDE drive.  Same thing with EmuTOS
512k and Aranym versions.

Both with Hatari and Aranym, EmuTOS does following NF output:
-------------
hda: DOS MBR byteswapped signature detected: enabling byteswap
 MBR at 0 $04
-------------

I've tried both Aranym built from Git(hub) and older release
in Debian, neither gives me the IDE drive, nor host dir drive.

(Why one still needs to provide CHS values for disks to Aranym?)
