Making RT-11 bootable

Jerome Fine replies: Two aspects of your question indicate you are a newbie RT-11 user: (a) You don't specify what you are booting on the RX50 - probably because you don't know - let alone which hardware type of computer is being used (b) You don't know the difference between mapped (e.g. RT11XM) and unmapped (e.g. RT11FB) monitors (equivalent to the kernel in UNIX according to Megan Gentry) in RT-11, let alone the details of how RT-11 handles the Qbus and Unibus versions of the hardware. Then, there is the difference with the PRO380 in that it uses a CTIbus (if I remember the name correctly), so additional device drivers are required to run with the PRO380 since the standard device drivers which work with the Qbus and Unibus will not function at all in the PRO380 environment. If your RX50 floppy was booting a Qbus (or Unibus) system, and you were running RT11XM, then add the following three files: PIX.SYS DZX.SYS DWX.SYS Then execute the command: COPY/BOOT:DZ DU0:RT11XM.SYS DU0: The RX50 floppy should then be able to boot on the PRO380. It will be UNABLE to boot using the DUX.SYS device driver on a Qbus (or Unibus) system using the RX50 floppy drive. If you also want to be able to boot RT11FB, then also add PI.SYS DZ.SYS DW.SYS If it works on the PRO380, please let us know. Do you also have a hard drive on the PRO380? It will use the DW(X).SYS device driver.
