| 21 | /* The following line tells the configuration script what sort of | |
| 22 | operating system this machine is likely to run. | |
| 23 | USUAL-OPSYS="note" | |
| 24 | ||
| 25 | NOTE-START | |
| 26 | Sun 1, 2 and 3 (-machine=sun1, -machine=sun2, -machine=sun3; | |
| 27 | -opsystem=bsd4-2 or -opsystem=sunos4) | |
| 28 | ||
| 29 | Whether you should use sun1, sun2 or sun3 depends on the | |
| 30 | VERSION OF THE OPERATING SYSTEM | |
| 31 | you have. There are three machine types for different versions of | |
| 32 | SunOS. All are derived from Berkeley 4.2, meaning that you should | |
| 33 | use -opsystem=bsd4-2. Emacs 17 has run on all of them. You will | |
| 34 | need to use sun3 on Sun 2's running SunOS release 3. | |
| 35 | ||
| 36 | For SunOS release 4 on a Sun 3, use -machine=sun3 and | |
| 37 | -opsystem=sunos4. See the file share-lib/SUNBUG for how to solve | |
| 38 | problems caused by bugs in the "export" version of SunOS 4. | |
