Hi All,

Running NetBSD 1.5_BETA2 on a Compaq M300 laptop, dual booting with Win2k...

I'm trying to mount the NTFS partition [onto /mnt] whilst running under NetBSD.
The question is what to use as the 'special device', for the mount command.
Since the laptop has a single IDE drive and I currently use 'fdisk -a' to change
the active partition and thus select which partition to boot on next power-up [0
is Win2k, 1 is NetBSD], then /dev/wd0 seems to relate only to 'areas' within the
NetBSD 'partition'. Is there a [or can I create] a special device file for areas
of the hard disk that are not within the NetBSD partition ?
