AWARD Bios-Update HOT-553 Mainboard
===================================
This file may not be up to date.
We are not liable for any damages caused by the bios-update.

Attention - read carefully!!!!
==============================
Instructions for Bios-Update to version 0A:
1) Do not update bios, if EPROM is manufactured by Intel.
   You can recognize the typ of flash eprom by removing
   the AWARD-label from the eprom. "i" stand for "Intel".
   Since Intel flash EPROMs on HOT-553 have a write-protected
   boot-block, you cannot update a higher version than 553WUQ07
   by flash programming.

   Flash EPROM = Intel (i) -> Bios Version: 553WUQ07 suggested
   Flash EPROM = MX, SST, Winbond,... -> no problem

   If you want to program the 553WUQ0D bios version on HOT-553
   and you have an Intel-Flash-EPROM on your mainboard
   then you have to use a hardware programming machine,
   because it's not possible by flash update.

2) Programming voltage for Flash-EPROM depends on manufacturer:
   12V -> Jumper 9 Pin 2-3 closed (MX and Intel)
   5V  -> Jumper 9 Pin 1-2 closed
3) Make sure that Password-setting is disabled in Bios-Setup.
4) Start DOS, but without any memory manager (e.g. EMM386.EXE)
5) Start program by entering:    AFLH52B <Bios-Filename>

   The <Bios-Filename> depends on the I/O-Chip (U3) of the
   onboard-controller

          553WUQ0D.BIN   UMC-I/O-Chip 
          553WSQ0A.BIN   SMC-I/O-Chip

   Make bios update with any ISA-VGA-Card,
   if old Bios-Version makes trouble with PnP.
6) After programming flash EPROM switch off system for a short time.
7) Load Bios-Default setting.
