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.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
