Flash-Bios-Update for PCI-486-Mainboard: HOT-433P
=================================================
Attention:
Before you change the BIOS or do any Flash update, please double check the version
of the HOT-433 that you have on hand.
433AUS33 or 433AUE33 for HOT-433 Rev. 4 only. (with UMC 8689 I/O)
433AUS2D or 433AUE2d for HOT-433 Rev. 3, Rev 2 and Rev 1 (with UMC 8683 I/O, with PS/2 mouse support)
433AUS2C == UMC8663 I/O, SST Flash
*If you do not know the revision number. Check on the UMC I/O number on-board.
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 EPROM - you can't update
this type by using software.
- 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) Start program: FLASH465 433AUS25.ROM (for Version 25)
(Start AWDFLASH if AWARD-Bios is running)
If the programming failed, you can start the programming on an other mainboard
with Flash EPROM. 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
- Cyrix 5x86 CPU (if error, then take an other CPU)
- MS-DOS Version 6.20 (take 6.22)
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.
