 | During install, NetBSD picks up the partition table ok:
 | 
 |     Start( MB)  Size( MB) Flg Kind
 |     ---------- --------- --- ----
 |  a:          0        200     Unknown (238)

 |  c:     146504       6123     NetBSD
 | 
 | but when trying to newfs, fails with
 | 
 |   Setting up DOS partition table
 |   newfs: /dev/rwd0a: open for read: Device busy
 | 
 | According to
 | 
 |   http://mail-index.netbsd.org/current-users/2008/06/29/msg003277.html
 | 
 | disabling GPT support fixes this, although I've not yet verified this myself.

 | Disable GPT support.
 
 You should be able to install on dk devices. Once wedges are active on wd0,
 you can only access wd0 from /dev/dk*; accessing it from /dev/wd* returns
 EBUSY as expected. The installed does not know about wedges so you lose.
