Find your favorite disk partitioning utility. Any formatter capable of partitioning a SCSI disk should work. Some of the ones that have been tried and seem to work are:
p l -bullet -compact t Apple HD SC Setup t Hard Disk ToolKit from FWB t SCSI Director Lite t Disk Manager Mac from OnTrack t Silverlining from LaCie t APS Disk Tools .El
p Apple's HD SC Setup is probably the easiest to use and the most commonly available. Instructions for patching HD SC Setup so that it will recognize non-Apple drives is available at:

p First, you need to choose a drive on which to install NetBSD. Try to pick a drive with a low SCSI ID number, especially if you are likely to add or remove drives to your SCSI chain in the future. .(tag Note: .Em Be sure you have a reliable backup .Em of any data which you may want to .Em keep. Repartitioning your hard drive is an .Em excellent way to destroy important data.
p Second, decide how you want to set up your partitions. At minimum, you need a partition to hold the .Nx installation (the root partition) and a partition to serve as swap. You may choose to use more than one partition to hold the installation. This allows you to separate the more vital portions of the filesystem (such as the kernel and the
a /etc No directory) from the more volatile parts of the filesystem. Typical setups place the
a /usr directory on a separate partition from the root partition. Generally, the root partition can be fairly small while the
a /usr No partition should be fairly large. If you plan to use this machine as a server, you may also want a separate
a /var No partition.
p Once you have decided how to lay out your partitions, you need to calculate how much space to allocate to each partition. A minimal install of NetBSD (i.e.
a netbsd.tgz , base.tgz , No and
a etc.tgz ) should fit in a 30M partition. For a full installation, you should allocate at least 80M. A general rule of thumb for sizing the swap partition is to allocate twice as much swap space as you have real memory. Having your swap + real memory total at least 20M is also a good idea. Systems that will be heavily used or that are low on real memory should have more swap space allocated. Systems that will be only lightly used or have a very large amount of real memory can get away with less.
p Next, use your favorite partitioning utility to make partitions of the necessary sizes. You can use any type of partition, but partitions of type "Apple_Free" might save you some confusion in the future.
p You are now set to install .Nx on your hard drive.
