7. Upgrading the Extender C5's flash memory

The C5 KVM uses flash memory technology which enables the firmware code to be upgraded by the user.
Upgrades are performed by using a PC program to download the new firmware via the keyboard connection. The
local transmitter and remote receiver both contain microprocessors with flash rewritable program memory. They
may be independently upgraded but we highly recommend that you always upgrade both the local and remote
units when performing an upgrade.
To perform a flash upgrade you will need to create an MS-DOS boot disk. This boot disk is used to run the upgrade
program automatically without the need for keyboard control. From DOS systems, a boot disk can be created using
the DOS FORMAT command (e.g. FORMAT A: /S). For Windows 95 and 98, DOS boots disks can be created in a
similar manner. For other versions of Windows refer to Windows Help for instructions. For example, a DOS disk
can be created from Windows XP by selecting My Computer, right clicking on the A disk icon, selecting Format
and then selecting Create an MS-DOS startup disk.
To upgrade the C5 KVM's firmware
STEP 1
Create an MS-DOS boot disk using a blank floppy disk.
STEP 2
Download the latest firmware upgrade files from the LINDY website (www.lindy.com). The firmware upgrade is
available as a compressed ZIP file containing the following files (xxx is the version number of the firmware – for
example 108 is version 1.08).
XKVMxxx.EXE
XREMxxx.HEX
XLOCxxx.HEX
AUTOEXEC.BAT
Copy these four files to the root directory of the MS-DOS boot disk (you will need to overwrite the AUTOEXEC.BAT
file that is currently on the DOS disk).
