JRC JUMP
tec
® Remote Control
The JUMP
tec
® Remote Control (JRC) is an extension of the PC BIOS that provides a way to
intercept and reroute certain BIOS functionality over a serial port at an early stage during the
system’s boot process.
Requirements:-
• Regular PC (host PC) running either
• Windows with jrc.exe installed
• MS-DOS with jrcd.exe installed
• Serial cable that connects either of the two PC com ports
Operating Instructions:
• Open a command prompt window on the host PC when running Windows
• Issue a connect command with the appropriate COM port and the desired baud rate.
jrc server.<com port><max baud rate>
• You can exit the server mode by pressing both control keys on the keyboard simulta-
neously.
Note ...
The boot diskette you create here is distinct from a Crisis Recovery Diskette.
See 5.8.2 on page 5-39 for details about creating the Crisis Recovery Diskette.
