prep revision 1.1 
      1 Before you start you should familiarize yourself with the boot PROM
      2 of your machine.  The older Decstation 2100 and 3100 cannot select
      3 a kernel from the command line. You need to set the bootpath
      4 environment variable to point to the disk and kernel you intend to boot.
      5 
      6 You should also examine the guide on the NetBSD/pmax web site, which
      7 has more complete and more up-to-date instructions than are given in
      8 the install document.

     10 	NOTE that the instructions on old versions of the web site
     11 	are incorrect. The installation miniroot image for both NetBSD 1.1
     12 	and 1.1 include the 8Kbytes reserved for bootblocks and disklabel.
     13 	The dd commands to write the miniroot to a freshly-labeleld
     14 	disk should have an 'skip=16' added to them, if the 'skip=16'
     15 	option is already present.

     18 If you're installing NetBSD/pmax for the first time it's a very good idea
     19 to look at the partition sizes of disk you intend installing NetBSD on.
     20 Changing the size of partitions after you've installed is difficult.
     21 If you do not have a spare bootable disk, it may be simpler to  re-install
     22 NetBSD again from scratch.

     25 Asumming a classic partition scheme with root (`/') and /usr filesystems,
     26 a comfortable size for the NetBSD root filesystem partition is about 20MB;
     27 a good initial size for the swap partition is twice the amount of physical
     28 memory in your machine (though, unlike Ultrix, there are no restrictions on
     29 the size of the swap partition that would render part of your memory
     30 unusable). A full binary installation, without X11 or other additional
     31 software, takes about 130MB in `/usr'.  This will be substantially reduced in
     32 the next release with support fo dynamically-linked shared libraries.
