The installation process needs the disk to be rq0 and have two floppies, rq1 and rq2. 32m-bin-1.0/01 needs to be attached as the first floppy and 32m-1.0-bin/02 needs to be attached to the second floppy. I chose to use the RD52 for installation as 1.0 doesn't understand any of the larger RD-series disks. /etc/disktab does have entries for the RA80 and RA81 but my recollection is that trying to install to those disks didn't actually work. > - What kind of error messages did you get when you wanted to install V1.2? > It looks like there is an issue with the bootloader - the self-tests go into an infinite loop. I have yet to try moving the bootloader from 1.0 to the 1.2 system, but I believe this should work. > - What microvax1 simulator did you use: the OpenSiḿh one or that from Simh > (Mark Pizzolato)? > I am using OpenSIMH but I don't believe there are any significant differences between the two branches that would affect this system. > - What is in your microvax1.ini file? > Here is an INI file for installing 1.0; you don't have to use the QVSS but I enjoy the experience. set cpu idle=ULTRIX-1.X set cpu INSTRUCTIONS=D-FLOAT set tti 7b set tto 7b set cr dis set lpt dis set rl dis set rq0 rd52 att rq0 rd52.dsk # The installer freaks out if the floppies are locked! #set rq1 lock set rq1 rx50 att rq1 32m-1.0-bin/01 #set rq2 lock set rq2 rx50 att rq2 32m-1.0-bin/02 set rq3 dis set ts dis set tq dis set qvss enable set xq type=deqna # change this to whatever works in your environment att xq tap:tap1 boot
