hello,
my harddisk is wd1. on it I have 4 dos-partitions :
- dos-partition 1 : winxp
- dos-partition 2 : NetBSD 1.6.1 i386
- dos-partition 3 : free
- dos-partition 4 : dos-extended partition

on the NetBSD slice (/dev/wd0) I have :
- /dev/wd0a /
- /dev/wd0b swap
- /dev/wd0e /usr

Questions : 
1 - I want to use the dos-partition 3 for my NetBSD box, howto do ?
then,
2 - I want to move /usr from dos-partition2 to dos-partition 3, howto do ?
then,
3 - I want to give the free area (from /usr) to / , howto do ?

I suppose I have to move swap to and from dos-partition3 for doing that.

thank's for help.
R.
