The BIOS IC is inserted in an IC socket which means that it can be removed and exchanged for another IC if necessary Is updating my BIOS necessary As a general rule if your system is functioning properly and you are not an experienced user do not try to update the BIOS Only if you have specific problems that a BIOS update may solve may it be advisable to update the BIOS The update process is pretty complex and you should bear in mind that if updating the BIOS goes wrong you may render your system unbootable Therefore do not update unless you know what you are doing Finding the latest official BIOS revision For the latest official BIOS revision please go to our website at www lucky star com tw On the support page you can find the latest BIOS files for our motherboards 31 4 1 Updating the BIOS As said this procedure is complicated only update your BIOS when you experience problems with your system Because each BIOS release completely overwrites the previous version and there is no need to update to intermediate BIOS releases when updating the BIOS Therefore always use the latest BIOS revision when doing a BIOS update The BIOS update procedure is as follows In order to flash update the BIOS you will need 2 files The BIOS binary file bin file from the website AWDFLASH EXE utility file This utility can be downloaded from our website Create a directory on your C harddisk drive and nam
