- 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.
