13.1.2 VFLASH Requirements
VFLASH is designed to operate in an IBM DOS compatible environment.
The MS-DOS operating system has been successfully tested with VFLASH; MS-DOS
compatible operating systems such as DR-DOS and PC-DOS should therefore support
VFLASH. Operating systems such as QNX and OS-9000 are not supported by VFLASH
(other utility programs are available for such operating systems; please contact our Technical
Support department for more information).
If you intend to directly program the onboard Flash device, VFLASH must be running on the
board.
If you need a remote computer to program the onboard Flash device (host), the board must be
configured in Download Mode and VFLASH must be running on the remote computer. A
serial cable must be connected between the remote computer and either the Serial Port 1 or
Serial Port 2, as it would be in VT100 mode (the remote computer is cabled like a VT100
terminal, see Section 15 - VT100 Mode).
NOTE
To run VFLASH properly, you need at least one floppy drive, 1 MB of
DRAM, MS-DOS
(version 3. 41 or higher).
13.2 RUNNING VFLASH
To run VFLASH, simply type "VFLASH" at the DOS prompt and press ENTER. Once the
front screen is passed, the main screen appears.
Use the up and down keys to highlight the option and then press ENTER to select an option.

or PC-DOS (version 2 or higher) or DR-DOS
Use this option when VFLASH is run on a board with Flash
EPROM to be programmed directly on the board.
Use this option when VFLASH is run from a remote computer,
or when your board has no floppy or hard disks, or simply
because the data to transfer is on a different computer than the
board and Flash EPROM disk. The transfer takes place via a
serial link on Serial Port 1 (3F8h) or Serial Port 2 (2F8h) from
the remote computer to the board.
