[pups] RE: Vtserver & 2.11 standalone progs

Robert and Warren, Robert asks: and Warren replies: The status is as follows. Feel free to relay onto the various newsgoups and lists; I obviously lack the time to :) - VTserver runs on my VAX (Ultrix-32 V4.4 and V4.5) - Client code is now in Ultrix-11 V3.1 I can get VTserver to upload the primary boot loader to the PDP-11 (I test with two.. a MicroPDP-11/23 and a MicroPDP-11/53) and that in turn makes the box load the Boot: program. When that is loaded, I can go two ways: - type "install" and Boot: will load the RAM disk from the server, and switch to that. Works. - manually load and run programs. Works. The problem here, is, that Ultrix uses a very complicated memory setup, which forces some MMU fiddling into all the drivers. Warren's driver was done for BSD and V7, which do not have this "problem". I am now adding this MMU support to the driver, and that's the end of it.. all other parts work fine. Here is a test run log. Falafel is the VAX 3100. My VTserver program uploads the boot code to the (Micro-)PDP-11 if the "-o" option is given. {falafel:~/ULT} $ vt -o Virtual tape server, $Revision: 2.3 $ stty cs8 -parenb 9600 clocal crtscts Opening port /dev/tty01 .... open Sending PDP-11 Boot Code to uODT ........................................................................

Type the escape character followed by C to get back, or followed by ? to see other options. This program performs operating system setup functions during installation and normal system operation. Setup operates in one of three possible modes (phases), depending on the current state of the system. The three modes are: Phase 1: Initial setup -- prepares system for first sysgen. Phase 2: Final setup -- completes the system setup. Phase 3: Change setup -- handles system setup changes. The program will ask several setup questions. Enter your answer to each question, using lowercase characters, then press <RETURN>. The questions include helpful hints enclosed in angle brackets < > and/or parenthesis ( ). If you need additional help answering any question, enter a ? or the word help then press <RETURN>. You can correct typing mistakes by pressing the <DELETE> key to erase a single character or <CTRL/U> to erase the entire line. You can interrupt the setup program by typing <CTRL/C>. This allows you to abort the setup process or restart it. Press <RETURN> to continue: Is the console terminal a CRT (video terminal) <y or n> ? y PLEASE CONFIRM: console is a VIDEO terminal <y or n> ? y ****** READING SETUP DATA FROM setup.info FILE ****** (vt(0,0)boot) - bad load device! The initial setup program cannot obtain the information it needs to complete the installation from the setup.info file. The sdload program writes this information into the setup.info file after loading the software onto the system disk. For some unknown reason the setup program cannot access the information. You can supply the missing information or abort the installation. If you continue, the program will prompt you for the following: o Setup phase number o System disk type o Target processor type o Software load device type Continue the installation <y or n> ? n ****** INITIAL SETUP ABORTED ****** You have the following options: o Restart the installation procedure at the beginning. o Execute the following steps to retry the initial setup: Halt the processor. Execute the hardware bootstrap for the system disk. The setup program should restart automatically, if it does not, execute: cd /.setup; setup. o Contact the Telephone Support Center or your local DIGITAL software services office for assistance. # ------------------------------------------------------------------------ and that's where it currently ends. I did already upgrade the root file system dump (hey.. I knew it was working once it started load that one.. :) so the kernel is already up to spec. I also have updated versions of /etc/rdate and /bin/date on it, so we can install using this era, and not go back to the early 70s :) Problems to be fixed: - icky parity stuff in VTserver (terminal mode) .. there are more problems with it. I think the receive buffer can overflow if we are in the main server_loop() routine... causing us to loose characters on input. - no kernel support for the VT device, so, past the initial load, we're still fucked, so to speak. In other words.. Warren, sweetie.. should we change our priorities and do the kernel driver first, and THEN redo the protocol as discussed last night? Cheers, Fred (**yawn** - 109 straight hours of coding :)
