Utility programs

Several custom utilities are included with MISE. They don't require MISE to operate, but they have proven useful during its development.

DISKDATE :d <date>

DISKDATE/CMD allows changing a logical drive's date field originally set by FORMAT or IDEFORM. :d is the logical drive number, and <date> can be any 8-character string. Enclose the date string in double quotes if it contains spaces.

Note: If a hard drive's date string does not have slashes ('/') as its third and sixth characters, re-installing its driver using IDEROM will produce an error message about the drive appearing to be unformatted. However, the drive will install and function normally.
JV1COPY <source> <destination>

JV1COPY/CMD copies JV1-format images between floppy diskettes and files on the hard drives. Only single density, single sided images are supported. The source and destination arguments can be filenames or drive numbers.

OUT <port> <byte>

OUT/CMD sends a data byte to the specified I/O port. Either argument can be specified in decimal or C-style hexadecimal notation. For example, the following two commands are equivalent:

OUT 0xF1 0x90
OUT 241 144


REBOOT/CMD reboots the Model I, reducing wear-and-tear on the long-suffering reset button. This is similar to LDOS's BOOT command, but runs much more quickly and reliably.


SETSYS/CMD sets or resets the System bit in a file's directory entry. The default is ON.

WHICH <filename>

WHICH/CMD searches for the specified file sequentially across all logical disks. It returns the full name, including drive number, of the matching file on the lowest-numbered drive.

If no filename extension is specified, /CMD is assumed. Thus WHICH determines which executable will be run when its name is entered on the LDOS command line.
