Hello list,
I'm trying to figure out the boot sequence on both the RK05 and RL02 drive from a PDP. Here's how I understand it so far:
1. Get the bootstrap in core either via the FP or PTR.
2. Execute bootstrap and pull in the absolute loader from 1st. sector of
512 bytes or 256 words;
i.e. copy 1st. sector of drive to core starting from 0
3. Execute absolute loader by a JMP 0.
4. ??? What happens next ???
Because of not (yet) having a RL02 nor a RK05, I'm using simh and trying to trace what's going on when I "attach rk0 rt11.dsk" and then a "boot rk0", but it's pretty difficult going..
Thanks.
