VFLASH SOFTWARE OVERVIEW

Depending on your particular configuration, VFLASH can transfer information to the
Flash disk by one of two methods:
1. If your TEK-AT4LVG is equipped with hard or floppy drives, then VFLASH
downloads data directly on the board's Flash EPROM disk.
2. If your TEK-AT4LVG does not have floppy or hard drives, then VFLASH must be run
from a remote computer which downloads data to the TEK-AT4LVG board via a serial
link on COM1 or COM2. This mode is recognized in the BIOS extension as Download
Mode and is enabled by installing jumper W19 (1-2) on the TEK-AT4LVG; in this
mode, the TEK-AT4LVG board waits for signals from the remote computer's VFLASH
software.
The first screen of the VFLASH software allows you to choose between direct and serial
downloading. The next screen is where the address and size of the Flash partition to
create are determined.(the screens are explained in section 12.03 - OUTPUT
SELECTION).
The next step is to select the files in the FILE SELECTION screen, which are to be
transferred to the Flash EPROM disk (explained in section 12.04 - FILE SELECTION).
The next screen is the LIST OF SELECTED FILES; here the file listing can be verified
and modified, duplicate files can be renamed or erased, and the Flash disk can be written
(also explained in section 12.04 - FILE SELECTION).
Finally, the last screen to appear is the TRANSFER STATUS OF ONBOARD FLASH
PROGRAMMING or
PROGRAMMING; this screen displays each of the transfer operations in progress
(explained in section 12.05 - FILE TRANSFER).
The above sections explain how to run the program in interactive mode via menus, but it
is also possible to run the program without menus by a command which specifies the
selected options and files with parameters; this mode is called batch mode (explained in
section 12.06 - BATCH MODE).
