Why can't we use the Int 13h drive parameters returned by the BIOS that
FreeLoader saves in the CM_DISK_GEOMETRY_DEVICE_DATA struct in the registry for
each disk? That's got all the information we need to easily distinguish between
32/64 and 63/255 disks. Class2 would need a bit of modification to parse the
hardware resources for the disk in order to find the struct, but I could make a
patch if you think it's an idea worth pursuing.
