BIOS Updates
G.1  Introduction
This appendix describes the procedure for rebuilding TM5000 BIOS files 
using floppy updates and reflashing BIOS ROM with the floppy updates.
G.2  Update Procedure
Use the following procedure to incorporate BIOS updates: 
1.Turn off the computer and reboot to a clean system (non-Windows 
environment). 
2.     Move to the UTILS directory.
3.     Type TIFLASH.EXE and press Enter.
4.    From the Flash main menu, choose Option 1. The Flash program then
asks if you want to save the old BIOS to FLASHBAK.IMG. Press Enter
to acknowledge. 
5.     The Flash program then prompts for the build file. If the BIOS upgrade
is on a floppy diskette, type:
A:\  and press Enter. 
The system will automatically select the most recent.TFB file and then
prompts you for where to store the BIOS file (press Enter to save the
new BIOS as FLASHROM.IMG). 
6.     The Flash program then prompts you where to save the data read from
the BIOS chip. Press Enter to select the default.
7.     The program then warns you that it is about to reload the BIOS. Press
Enter. The Flash program then erases/reprograms the FlashROM
chip and reboots the system.
