| 4.1 BSD | |
 Logging into a 4.1 BSD system | |
| Type: | Multitasking, multiuser |
|---|---|
| Creator: | CSRG |
| Architecture: | VAX, theoretically portable |
| This Version: | 4.1 (1981) |
| Date Released: | 1981 |
This version addressed many of the performance shortcomings in 4.0 BSD that were brought up in a VMS vs BSD paper. Many of the changes are outlined in Bug fixes and changes in 4.1bsd.
Other features included:
- job control
- automatic kernel config
- vfork()
4.1 was largely a debug version with several interm releases. There is a known 4.1, 4.1a and 4.1c release, and possibly others.
Getting this to run
4.1
A tape image for 4.1 has surfaced on bitsavers, named 4.1_BSD_19810710.zip The bootblock programs do not run under SIMH using the 4.0 BSD strategy, however it is possible to swap tapes when restoring the root slice, and then restoring the tars. Using this modified tape, I've created an installation guide [Installing 4.1 BSD on SIMH].
4.1c
This version includes the Bill Joy TCP/IP implementation.
