20c428fd JB |
26 | operating system this machine is likely to run. |

29 | NOTE-START | |
30 | Sun 1, 2 and 3 (-machine=sun1, -machine=sun2, -machine=sun3; | |
31 | -opsystem=bsd4-2 or -opsystem=sunos4) | |
32 | ||
33 | Whether you should use sun1, sun2 or sun3 depends on the | |
34 | VERSION OF THE OPERATING SYSTEM | |
35 | you have. There are three machine types for different versions of | |
36 | SunOS. All are derived from Berkeley 4.2, meaning that you should | |
37 | use -opsystem=bsd4-2. Emacs 17 has run on all of them. You will | |
38 | need to use sun3 on Sun 2's running SunOS release 3. | |
39 | ||
40 | For SunOS release 4 on a Sun 3, use -machine=sun3 and | |
41 | -opsystem=sunos4. See the file share-lib/SUNBUG for how to solve | |
42 | problems caused by bugs in the "export" version of SunOS 4. | |
