This 83is further referred to as 'labeling' a disk. 84 85First you get the chance to edit or create an AHDI compatible partitioning on 86the installation disk. Note that NetBSD can do without AHDI partitions, 87check the documentation. 88If you want to use an AHDI compatible partitioning, you have to assign some 89partitions to NetBSD before NetBSD is able to use the disk. Change the 'id' 90of all partitions you want to use for NetBSD filesystems to 'NBD'. Change 91the 'id' of the partition you wish to use for swap to 'SWP'. 92 93Hit the <return> key when you have read this... 94__md_prep_disklabel_1 95 getresp "" 96 ahdilabel /dev/r${1}c 97 98 # display example 99 cat << \__md_prep_disklabel_3 100Here is an example of what the partition information will look like once 101you have entered the disklabel editor.
