Flash-Bios-Update for PCI-486-Mainboard: HOT-433P
=================================================

Attention:
This file may not be up to date.
We are not liable for any damages caused by the bios-update.

1) Is there a Flash-EPROM (EEPROM) on the mainboard?
   Remove the "AMI"-label on the EPROM-Chip...
   - Is there a window, then it's an normal EPROM - you can't update
     this type by using software. You'll programm 433AUE2A.ROM by
     using a hardware programmer.
   - It's a "SST"- or "Winbond"-Chip: you can update by software.
2) Remove any memory-manager (EMM386.EXE)
3) Clear any password settings in BIOS-Setup.
4) Set Bios if possible: Chipset Setup - Main BIOS Cacheable: non-cacheable
5) Start program:    FLASH465 433AUS2C.ROM    (for Version 2C)
   (Start AWDFLASH if AWARD-Bios is running)

If the programming failed, you can start the programming on an other HOT-433P
or HOT-539P-Mainboard. Before you confirm the programming, you can change the
EPROM with the defect one (while system is running).

The bios update could be impossible with
- when now the version is 15 or 16 and your CPU is Cyrix 5x86 CPU
  (if error, then take an other CPU)
- MS-DOS Version 6.20 (take 6.22)

Additional information
======================

AMD DX4-100 NV8T  Configure like AMD DX4, 3,45V, internal Cache: Write Trough
AMD DX4-100 SV8B  Configure like Intel P24D, internal Cache: Write Back (JP24
                  and also in BIOS Setup), 3,45V
Cyrix DX4-100 GP/OP  Configure like Cyrix M7 DX2, 3,45V, Bios 15 or higher
Cyrix DX4-100 GP4/OP4  Configure like AMD (NV8T) DX4, 3,45V, Bios 15 or higher
Cyrix M1sc 5x86  Configure like AMD SV8B above, Bios 15 or higher
AMD 5x86 P75 X5-133  Configure like AMD SV8B above, Bios 23 or higher
                  and set System/CPU-Clock-Multiplier to 1:2 (JP 18)

Bios-Version
============
You can determine Bios-Version by reading the number below the screen:
for example: 41-P315-... is Version 15
             41-P725-... is Version 25
             41-P82A-... is Version 2A

If you set the System-Clock to 40 MHz for 40/80/120 CPUs, you must test the
PCI-Components if they run with this frequence. Take notice of PCI-Spec: it
is specified up to 33 MHz, but some components run also with 40 MHz.
50 MHz is in all cases too much.
