How does one do this?  I tried installboot -c /dev/rwd0c but get the following:

# installboot -v -c /dev/rwd0c
installboot: Opening file system `/dev/rwd0c' read-only: Device not configured

The Windows parrtition is actually /dev/rwd0e so I tried that:

# installboot -v -c /dev/rwd0e
File system:         /dev/rwd0e
File system type:    raw (blocksize 8192, needswap 0)
Primary bootstrap:   (to be cleared)
installboot: i386: bootstrap removal is not supported
installboot: Clear bootstrap operation failed

Is there some other method to remove the NetbSD boot selector/loader thing?
I recently had to reinstall windozeXP and I'm getting an "Error 3" when selecting
XP.  I though maybe installing a different boot manager would fix things so I
installed GAG-4.6, however selecting XP still dumping me into the NetBSD boot
selector so I think I just need to clear it out.

I thought I recalled seeing something about this on one of the lists but I can't
seem to find much about this.

Cheers,
Jeff W.
