    12.01 INTRODUCTION VFLASH is TEKNOR's Flash EPROM transfer utility program for single board computers. Its main function is to download DOS files to the 2 or 4 MB Flash EPROM disk U37, 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.

  • Page 125: Vflash Software Overview

    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.

  • Page 126: Types Of Flash Eprom Disks

    12.01.2 TYPES OF FLASH EPROM DISKS With VFLASH, you can create two types of Flash EPROM disks: This type of Flash EPROM disk must start from the first block OOTABLE LASH and is recognized by the BIOS. Like a hard disk, an active Flash EPROM disk can boot your system.

  • Page 127: Vflash Requirements

    If you intend to directly program Flash device on the TEK-AT4LVG, VFLASH must be running on board. If you need a remote computer to program Flash device on the TEK-AT4LVG (host), then the board must be in Download Mode and VFLASH must be running on the remote computer.

  • Page 163: Vt100 Requirements

    15.01 VT100 REQUIREMENTS To use VT100 Mode, the board must be supplied with ±12 volts. This is the voltage required by the RS-232 drivers. The terminal you are using should emulate a VT100 or ANSI terminal. Although this is not an absolute requirement, strange characters may appear on screen if it does not. This occurs because the VT100 recognizes these control characters, and causes them to perform a specific function, for example, screen erase, cursor position, and so on.

    15.03 RUNNING WITHOUT A TERMINAL The TEK-AT4LVG can boot up without a screen or terminal attached. However, if VT100 Mode is desired, but the terminal is to be disconnected, you must ensure the control lines are in an active state. Failing this, the system may "hang" while waiting for the control lines to become active.

    DOWNLOAD MODE Information can be downloaded to the Flash EPROM disk on the TEK-AT4LVG by running VFLASH on a remote computer and using a serial link. This is referred to as Download Mode and is enabled by installing jumper W19(1-2).

    Following is a list of the most frequently Questions/Answers we meet at our Technical Support Department. If any trouble appears while using the TEK-AT4LVG, please check this list first. If the trouble still persists, contact TEKNOR’s Technical Support Department. My computer does not retain the information entered in the AWARD BIOS setup (CMOS).
  • Page 169 My TEK-AT4LVG is used in a RS-485 party line network. The network is flaky (intermittent). Any reasons ? In party line operation, 120 ohms termination resistors are used on both ends of the network. All TEKNOR SBCs are shipped with default 120 ohms resistors on both TX(+/-) and RX(+/-) lines.
