Over the holidays I upgraded one of my servers from a 4/280 to a 4/490 and in the process upgraded the OS from 4.0.3 to 4.1.1. This server servers a few 4/110's and several Sparcstations (1 and 1+). Most of the SS have a local 104meg disk that is used for swap only (Twiddling bits in images can us lots of swap space.) Under 4.0.3 the config line in the kernal configuration file looked like: config vmunix swap on sd0b Under 4.1.1 that does not work. The SS download the kernal from the server and proceeds with the bus probe. The it is supposed to show where the root, swap and dump areas are located. It displays the root area and then hangs. After some hacking around with a large amount of help from one of the local Sun Office people who came out to help (Thanks, Bob) we found the following worked: config vmunix swap on type spec sd0b This line is used to set up the confvmunix.c file located in the kernel make directory. This file has structures as to where the root, swap, and dump area are located. The man pages for config(8) do not mention this as a legal syntax for the swap area. We couldn't find this in the manual. If anybody knows anything about this, I'd appreciate hearing about it.
