SECTION 11
VFLASH SOFTWARE
11.01 INTRODUCTION
VFLASH is TEKNOR's Flash EPROM transfer utility program for single board computers. Its
main function is to download DOS files to the 2MB or 4MB Flash EPROM disk (U36 on solder
side), also referred to as data Flash.
A Flash EPROM disk created with VFLASH is very much like a hard disk. A partition is
created and data is stored in files, just like on a hard disk. The main difference between the two
is that this Flash disk is a read-only drive. Therefore, in order to write software to this Flash
disk, you must use the VFLASH Transfer Utility.
However, with the FLASH FILE SYSTEM II software from Microsoft, Flash EPROM disks are
read/write and may be accessed via DOS commands (this utility is covered in Section 12).
This Section will describe how to use the VFLASH software utility.
11.01.1 VFLASH SOFTWARE OVERVIEW
Depending on your particular configuration, VFLASH can transfer information to the Flash
disk in one of two methods:
1. If your VIPer807 is equipped with hard or floppy drives, then VFLASH downloads data
directly on the board's Flash EPROM disk.
2. If your VIPer807 does not have floppy or hard disks, then VFLASH must be run from a
remote computer which downloads data to the VIPer807 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 W22 (1-2) on the VIPer807; in this mode, the VIPer807 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 screen is explained in section 11.02 - OUTPUT SELECTION/FIRST
SCREEN).
The next screen is where the address and size of the Flash partition to create are determined
(explained in section 11.03 - OUTPUT SELECTION/SECOND SCREEN).
