Kontron Remote Control Software (JRC)

Introduction

The Kontron JUMPtec Remote Control (JRC) is an extension of the PC BIOS that provides a way to intercept and re-route certain BIOS functionality over a serial port at an early stage during the system’s boot process.

There are two different aspects how this interception is utilised:

• The Server Mode provides a way of intercepting screen output from and keyboard input to the client on the host machine. In Server Mode it is possible to map the host´s floppy drive to the client´s drive specified A:. The host can also emulate a single disk drive as a file on the host machine's hard disk. This file can be created with the command IMGCREATE and is accessible from the client machine as drive A:.
• The second aspect is Image Mode which provides a way of halting the boot process of the client. This allows the host machine to read or write the contents of the CMOS RAM, EEPROM CMOS mirror, NVRAMs of other JUMPtec boards as well as the contents of any flash, hard or floppy disks of the client.

Requirements

• Kontron PC with BIOS that supports JRC (Client PC).
• Regular PC (Host PC) running either.
  • Windows 95/98/ME/NT/2000/XP with JRC.EXE installed.
  • MS-DOS with JRCD.EXE installed.
• Null modem serial cable that connects any of the two PCs COM ports.
