The link to the "AMI MMTool v3.26" has been removed upon demand of American Megatrends Inc. a) Non-UEFI AMI BIOS tool MMTool v3.26 (for older AMI BIOSes without UEFI structure):.Here are the download links to the available tools, which are able to open and modify BIOSes with an AMI platform: Then you should see the name of the BIOS platform. Tip: If you don’t know the architecture of your mainboard BIOS, you can find it out by starting your computer and entering the BIOS. Award (Note: Intel and Dell mainboard BIOSes use another platform and connot be opened and modified by the tools, which are listed here.). The most popular BIOS platforms are made by AMI (American Megatrends Inc.) and by Phoenix resp. The choice of the suitable BIOS modding tool depends on the BIOS platform of your special mainboard/system. the actual mainboard BIOS for your system (get it from the manufacturer).Download the following files and tools: (Note: The offered files have to be unzipped by using WinRAR v5.xx!) This is what you should prepare, if you want to extract, to add or to replace any PCI ROM module from any mainboard BIOS: Preparations (valid for nearly all AMI/Award/Phoenix BIOSes) Within my BIOS modding guides you may find some tips how to pass this restriction. Some Gigabyte and ASUS mainboard BIOSes can be modified, but the flash procedure is checksum sensitive.Some old Phoenix BIOSes cannot be opened and modified by any common version of the tool CBROM.BIO cannot be opened and modified by any standard BIOS tool. Intel mainboards are equipped with an especially modified BIOS.Not all mainboard BIOSes can be easily modified by the user. That is why this guide is usable for the modification of any PCI ROM module from any vendor. As a consequence an extracted PCI ROM file usually can be inserted into each mainboard BIOS, which already contains the same sort of PCI ROM module.īasically the extraction and the replacement procedure of all PCI ROM modules is quite similar. Each PCI ROM module version, which has been delivered from the Controller chip vendor to the mainboard manufacturers, is identical and not dependent on the BIOS structure (AMI/Phoenix/Award) the mainboard manufacturer is using. Nevertheless it is possible to extract any PCI ROM module and to replaced it by another version, because the entire mainboard BIOS file has a modular structure.Īlthough the BIOS files are developed and published by the mainboard manufacturer, the inserted PCI ROM modules were made by the vendor of the related on-board Controller chips. The PCI ROM modules are within the mainboard BIOS file and only visible by opening the BIOS file with a special tool like MMTool or CBROM. That is the reason why users with an AHCI (non-RAID) system will not benefit from an update of the RAID ROM version. The Intel SATA AHCI Controller of the mainboard is not supported at all by the RAID ROM module. Everything you are doing will be at your own risk.Īctual BIOS files do not contain any separate AHCI ROM module, because such BIOS module resp. There is no warranty regarding the safety of my BIOS modding guides and the linked BIOS and PCI ROM files. This is why I recommend to flash a modded BIOS only for experienced users, who know about the risks and do all necessary preparations for a possible failure of the BIOS update process (inclusive a complete backup of their data). In the worst case you may not be able to use the computer anymore until you will get a new and working BIOS chip from the manufacturer of your mainboard. Warning: Modding a BIOS file by updating the inserted PCI ROM module is neither very difficult nor risky, but it is dangerous, if you are going to flash a modded BIOS into the BIOS chip of a mainboard. Since I have some experience regarding the extraction and replacement of PCI ROM modules, which are part of the mainboard BIOS, I decided to create and to publish step-by-step guides for the different AMI/Award/Phoenix BIOS structures.Īlthough these detailed instructions are mainly written for users, who want to update the Intel RAID ROM module of their mainboard BIOS, they basically can be used for the extraction and replacement of any other PCI ROM module too.īIOS Modding: Introduction and Preparations All experienced and courageous users, who want to update a PCI ROM module of their mainboard BIOS:
