Some of the ones that have been 5tried and seem to work are: 6 7 Apple HD SC Setup 8 Hard Disk ToolKit from FWB 9 SCSI Director Lite 10 Disk Manager Mac from OnTrack 11 Silverlining from LaCie 12 APS Disk Tools 13 14Apple's HD SC Setup is probably the easiest to use and the most commonly 15available. Instructions for patching HD SC Setup so that it will recognize 16non-Apple drives is available at: 17 18 http://www.euronet.nl/users/ernstoud/patch.html 19 20First, you need to choose a drive on which to install NetBSD. Try to pick a 21drive with a low SCSI ID number, especially if you are likely to add or 22remove drives to your SCSI chain in the future. 23 24NOTE: BE SURE YOU HAVE A RELIABLE BACKUP OF ANY DATA WHICH YOU MAY WANT TO 25KEEP. REPARTITIONING YOUR HARD DRIVE IS AN EXCELLENT WAY TO DESTROY 26IMPORTANT DATA. 27 28Second, decide how you want to set up your partitions. At minimum, you 29need a partition to hold the NetBSD installation (the root partition) and a 30partition to serve as swap. You may choose to use more than one partition 31to hold the installation. This allows you to separate the more vital 32portions of the filesystem (such as the kernel and the /etc directory) from 33the more volatile parts of the filesystem. Typical setups place the /usr 34directory on a separate partition from the root partition. Generally, the 35root partition can be fairly small while the /usr partition should be 36fairly large. If you plan to use this machine as a server, you may also 37want a separate /var partition. 38 39Once you have decided how to lay out your partitions, you need to calculate 40how much space to allocate to each partition. A minimal install of NetBSD 41(i.e. netbsd.tgz, base.tgz, and etc.tgz) should fit in a 30M partition. 42For a full installation, you should allocate at least 80M. A general rule 43of thumb for sizing the swap partition is to allocate twice as much swap 44space as you have real memory. Having your swap + real memory total at 45least 20M is also a good idea. Systems that will be heavily used or that 46are low on real memory should have more swap space allocated. Systems that 47will be only lightly used or have a very large amount of real memory can 48get away with less. 49 50Next, use your favorite partitioning utility to make partitions of the 51necessary sizes. You can use any type of partition, but partitions of type 52"Apple_Free" might save you some confusion in the future. 53 54You are now set to install NetBSD on your hard drive. 55
