CI Commands Implemented in Separate Programs

The Command Interpreter (CI) delegates some of its functions to auxiliary programs. While CI itself executes most CI commands, several are executed by auxiliary program CIX, and others are auxiliary programs in themselves. For example, CI implements the DL command by running the program DL.

For each of these programs, the memoryimage program file must be accessible to FmpRunProgram. It is most convenient to locate these programs in the directory PROGRAMS; however, refer to the description of UDSP in the RTEA User's Manual for other options. The following are the commands executed by auxiliary program CIX:

AT, CL, CO, CR, CRDIR, DC, IN, MO, PROT, PU, OWNER, TM, UNPU, RN

Format System

It is a good idea to generate a system with the VSCSI, FORMC, FORMT, or FORMF program in it, using the target system I/O configuration. VSCSI is used for formatting SCSI disks. FORMC is used for sparing bad tracks on the HP 7908, 7911, 7912, 7914, 7933, 7941/42, 7945/46 (CS/80) disks, while FORMT is used for formatting HP 7906, 7920, 7902, 9121 and 9895 minidisks, and 7925 disks. All other nonCS/80 disks are spared transparently using the FORMF utility. The FORMT program requires a dedicated system with only one ID segment, the one for FORMT. Put this system, the •format" system, together using the BUILD program.

Create two boot command files: one to boot the target system (with the reconfigured disk structure) from a tape drive, and one to boot the new system from your hard disk.

Store the format system, the target system, CI, D.RTR, and INSTL program files, the two boot command files, and the snapshots for the systems on one tape. Boot the target system from the floppy disk/tape and verify operation.

If you are using a SCSI disk, use VSCSI to format your disk.

If you are using a nonCS/80 disk, use either FORMF or FORMT to format your disk. If you are using a CS/80 disk, use FORMC to spare any known bad tracks.

Boot the target system from floppy disk or tape. Mount, initialize, and run the INSTL program on the reformatted hard disk cartridges. Copy the target system file, its snapshot file, the boot command file, the D.RTR program file, and the CI program file to the hard disk.

Boot the target system from the hard disk and copy your files from the backup disks or cartridge tape.
