>Description:
When I run /sbin/fdisk after I updated fdisk.c to Revision 1.100,
the following message is displayed:
# fdisk wd0
fdisk: removing corrupt bootsel information
fdisk: Cannot determine the number of heads
fdisk failed in sanity check (xheads == -1),
but when I remove this check, it works:
--- fdisk.c.orig 2006-06-03 00:02:51.000000000 +0900

if (xheads == -1)
