Logging into a 4.1 BSD system
|Architecture:||VAX, theoretically portable|
|Current Version:||4.1 (1981)|
Other features included:
- job control
- automatic kernel config
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
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.
My simplified notes are:
mkfs /dev/hp0g 145673 cd /dev MAKE ht0 mount /dev/hp0g /usr cd /usr mt rew mt fsf mt fsf tar -xvf /dev/rmt0 dd if=/usr/mdec/uboot of=/dev/rhp0a bs=1b count=1 cp /etc/fstab.rp06 /etc/fstab
with a bootlog of:
