However, when formatting the disk, Windows or MSDOS may write the 
current BIOS geometry in it, and it is likely to be the problem.

If I disable the BIOS translation (for example by commenting 
'bdrv_set_geometry_hint()' or by removing 'rtc_set_memory(s, 0x39, val)' 
in hw/pc.c), then NT 4.0 won't see disks bigger than 512 MB. So a better 
solution must be found.
