This 72is further referred to as 'labeling' a disk. 73 74First you get the chance to edit or create an AHDI compatible partitioning on 75the installation disk. Note that NetBSD can do without AHDI partitions, 76check the documentation. 77If you want to use an AHDI compatible partitioning, you have to assign some 78partitions to NetBSD before NetBSD is able to use the disk. Change the 'id' 79of all partitions you want to use for NetBSD filesystems to 'NBD'. Change 80the 'id' of the partition you wish to use for swap to 'SWP'. 81 82Hit the <return> key when you have read this... 83__md_prep_disklabel_1 84 getresp "" 85 ahdilabel /dev/r${1}c 86 87 # display example 88 cat << \__md_prep_disklabel_3 89Here is an example of what the partition information will look like once 90you have entered the disklabel editor.

At this stage, the only thing you _must_ setup 138is a swap partition. If you wish, the remaining partitioning work might 139be delayed until the actual installation. 140 141As with anything which modifies your disk's contents, this 142program can cause SIGNIFICANT data loss, and you are advised 143to make sure your data is backed up before beginning the 144preparation process. 145 146Default answers are displayed in brackets after the questions. 147You can hit Control-C at any time to quit, but if you do so at a 148prompt, you may have to hit return. 149__welcome_banner_1 150} 151 152md_not_going_to_install() { 153 cat << \__not_going_to_install_1 154 155OK, then.

You have successfully partitioned your disks! 168Now you can use file2swap.ttp to transfer the install.fs to your 169swap partition and continue the installation. 170Enter halt at the command prompt. Once the system has halted, reset the 171machine and re-boot it. 172 173Note: If you wish to have another try. Just type '^D' at the prompt. After 174 a moment, the installer will restart itself. 175 176__congratulations_1 177} 178
