How to update Motherboards BIOS PC-CHIPS

1. Check to see what type of flash chip you have in your Mb. There are two types of flash memory, Large Block and Small Block. We label them as "L" or "S" respectively. When you first turn the computer on. The screen will show the BIOS date code and a letter with "L" or "S".
2. Down load the right type of BIOS according to what type of flash chip you got in your MB.
3. Down load the right BIOS flash utilities.
4. Make sure the Voltage on the flash chip were set to 12V on your Mb
5. Make a clean Bootable Disk that has no config.sys and autoexec.bat file. Copy BIOS file and Flash Utility to the floppy.
6. Put this bootable diskette in drive A: and boot the system into A:>
7 Run award or AMI flash utility to flash the bios.

Come aggiornare il bios di una Motherboard PCCHIPS

1. Occorre innanzitutto capire che tipo di flash eeprom sia installata sulla vostra mainboard. Ci sono due tipi di memorie flash eeprom, Large Block and Small Block. Noi indicheremo tali tipi di eeprom rispettivamente con le etichette "L" o "S" . Quando accendete il vostro pc, sul monitor apparira' la data di rilascio del BIOS ed una lettera , che sara' "L" oppure "S": dal tipo di lettera potete dedurre anche il tipo di flash eeprom installata e quindi anche il corretto aggiornamento bios da usare.
2. Scaricate l'aggiornamento bios adattoal tipo di flash eeprom installata sulla vostra MB.
3. Scaricate l'utility corretta per effettuare il flash.
4. Assicuratevi che il voltaggio del bostro chip flash sia settato a 12V usando l'apposito jumper presente sulla MB
5. Create un disco di Boot privo dei file config.sys ed autoexec.bat. Copiate il file BIOS e la Flash Utility su tale floppy.
6. Inserite il floppy nel drive A: ed effettuate da esso il boot
7 Eseguite l'utility Award o Ami per flashare il bios.
