By looking at hdimage file created by mkfatimage16m I noticed that
the boot sector was at offset 0x2280, rather than at 0, if it was
a device /dev/hda1.  So I truncated the hdimage file by cutting off
the first 8832 bytes and redid the mount command above and it worked!

However, dosemu will not work if $_hdimage is set to the truncated
image.  So I need a way to specify the file starting at offset 0x2280,
while leaving it intact...  But I do not know how to specify a file
starting at a byte offset...
