2.3 CD Installation - Disk setup

2.3.1 Disk formatting

The slice layout on the newly formatted disk or partition needs to be set up, using this command.

          # fdisk -u
          

If there are multiple operating systems on the disk, pick the correct partition judging by what partitions were created earlier with a resizing tool.

2.3.2 Boot block installation

The 'ad0' here refers to the first disk on the first IDE bus of a computer. Increment the number if the target disk is farther down the chain. For example, the master disk on the second IDE controller would be 'ad2'.

          # boot0cfg -B ad0
          # boot0cfg -v ad0
          

-s SLICE, where SLICE is a number, controls which slice on disk is used by boot0cfg to start from. By default, this number is 1, and will only need modification if a different slice contains DragonFly.

Use -o packet as an option to boot0cfg if the DragonFly partition is located beyond cylinder 1023 on the disk. This location problem usually only happens when another operating system is taking up more than the first 8 gigabytes of disk space. This problem cannot happen if DragonFly is installed to a dedicated disk

2.3.3 Disklabel

If DragonFly is installed anywhere but the first partition of the disk, the device entry for that partition will have to be created. Otherwise, the device entry is automatically created. Refer to this different partition instead of the 'ad0s1a' used in later examples.

          # cd /dev; ./MAKEDEV ad0s2
          

The partition needs to be created on the DragonFly disk.

          # disklabel -B -r -w ad0s1 auto
          

Using /etc/disklabel.ad0s1 as an example, issue the following command to edit the disklabel for the just-created partition.

          # disklabel -e ad0s1
          

2.3.4 Partition Format

newfs will format each individual partition.

          # newfs /dev/ad0s1a
          # newfs -U /dev/ad0s1d
          # newfs -U /dev/ad0s1e
          # newfs -U /dev/ad0s1f
          # newfs -U /dev/ad0s1g
