Subject: Standalone support for RX02 added (#282) Index: pdpstand/rx.c,mdec/rx0{1,2}uboot.s 2.11BSD Description: Support has been added to 'boot' and the rest of the standalone utilities for the RX02 (in both single and double density modes). Boot blocks have also been created for the RX02 (again in both single and double density). Repeat-By: Try to boot from an RX02. Fix: Many thanks go to Tim Shoppa (shoppa@krl.caltech.edu) for the latest addition to 2.11BSD - all I did was provide answers to a few questions on what a standalone driver and bootblock needs to do. The shar archive which follows contains two files: 1) A shar archive containing new files to be added to the system. The files which will be added are: /usr/src/sys/mdec/rx01uboot.s /usr/src/sys/mdec/rx02uboot.s /usr/src/sys/pdpstand/rx.c 2) A patch file.
