Bootup Mode
The next display shows the current bootup mode.
SELECT AUTOBOOT OR
NON-AUTOBOOT
NON-AUTOBOOT
Your choices are:
NON-AUTOBOOT
AUTOBOOT
You would choose NON-AUTOBOOT if you want to communicate with a remote PC workstation running Cyrano 200
or OptoControl. You would choose AUTOBOOT if your applications program has been downloaded to the G4LC32
and debugged. Choosing AUTOBOOT will allow you to run your applications program from the G4LC32, stand-
alone, without a PC workstation. The factory default is NON-AUTOBOOT. Just press the
ENTER
key if you do not
choose to change this option. If you choose to change the AUTOBOOT option, then press the left/right arrow keys
to make your selection. After making your selection, then press the
ENTER
key to accept the change.
Loader/Kernel Bootup
The next display shows the current kernel or loader bootup setting.
BOOT TO -
KERNEL
Use the left/right arrow keys to select the BOOT TO LOADER or BOOT TO KERNEL setting. BOOT TO KERNEL is the
factory default setting. The LOADER is a protected section of code in the Flash EPROMs with basic bootup and
download functions, cannot be modified, and cannot run programs without the appropriate KERNEL. The Cyrano or
OptoControl KERNEL is downloadable code appended to the LOADER and has the instructions to run user programs.
Choose the BOOT TO LOADER setting if the Flash EPROMs have been corrupted. Use the FLASH200 or OptoTerm
utility to download the appropriate kernel, then change the setting back to BOOT TO KERNEL.
Press
ENTER
to select the KERNEL or LOADER bootup mode.
