I never used $_hdimage="/dev/hda1 ...". 

I think it's much safer to let Linux to manage FAT partitions and use 
LREDIR to access mounted FAT partitions. It may be tricky to setup
to get the same drives as I'm booting DOS (or Windows) though.

Problems with DOSEMU: 
	absence of support of LFN (I think it would be possible to do that 
		for stuff accessed with lredir, but somebody should write
		support of that...)

	also doesmu-1.0.0 doesn't want to work nicely for me on console
	with 2.4 prereleases
