This article is about the BIOS as found in IBM PC compatibles. For other uses, see Bios disambiguation. For IBM PC compatible computers, BIOS BY oss an acronym for Basic InputOutput System and also known as the System BIOS, ROM BIOS or PC BIOS is non volatile firmware used to perform hardware initialization during the booting process power on startup, and to provide runtime services for operating systems and programs. The BIOS firmware comes pre installed on a personal computers system board, and it is the first software run when powered on. The name originates from the Basic InputOutput System used in the CPM operating system in 1. Originally proprietary to the IBM PC, the BIOS has been reverse engineered by companies looking to create compatible systems. E37439_01/html/E36285/figures/mb1b.png' alt='What Is Microcode Patch' title='What Is Microcode Patch' />The interface of that original system serves as a de facto standard. The BIOS in modern PCs initializes and tests the system hardware components, and loads a boot loader or an operating system from a mass memory device. In the era of MS DOS, the BIOS provided a hardware abstraction layer for the keyboard, display, and other inputoutput IO devices that standardized an interface to application programs and the operating system. More recent operating systems do not use the BIOS after loading, instead accessing the hardware components directly. Most BIOS implementations are specifically designed to work with a particular computer or motherboard model, by interfacing with various devices that make up the complementary system chipset. Originally, BIOS firmware was stored in a ROM chip on the PC motherboard. What Is Microcode Patch' title='What Is Microcode Patch' />In modern computer systems, the BIOS contents are stored on flash memory so it can be rewritten without removing the chip from the motherboard. This allows easy, end user updates to the BIOS firmware so new features can be added or bugs can be fixed, but it also creates a possibility for the computer to become infected with BIOS rootkits. Furthermore, a BIOS upgrade that fails can brick the motherboard permanently, unless the system includes some form of backup for this case. Unified Extensible Firmware Interface UEFI is the successor to BIOS, aiming to address its technical shortcomings. Historyedit. C P M B A S I C I O S Y S T E M B I O S. COPYRIGHT C GARY A. KILDALL. JUNE, 1. B A S I C D I S K O P E R A T I N G S Y S T E M B D O S. COPYRIGHT C GARY A. KILDALL. JUNE, 1. An excerpt from the BDOS. PLM file header in the PLM source code of CPM 1. CPM 1. 2 for Lawrence Livermore Laboratories LLL2The term BIOS Basic InputOutput System was created by Gary Kildall5 and first appeared in the CPM operating system in 1. CPM loaded during boot time that interfaces directly with the hardware. A CPM machine usually has only a simple boot loader in its ROM. Versions of MS DOS, PC DOS or DR DOS contain a file called variously IO. SYS, IBMBIO. COM, IBMBIO. SYS, or DRBIOS. SYS this file is known as the DOS BIOS also known as DOS IO System and contains the lower level hardware specific part of the operating system. Together with the underlying hardware specific, but operating system independent System BIOS, which resides in ROM, it represents the analogue to the CPM BIOS. With the introduction of PS2 machines, IBM divided the System BIOS into real mode and protected mode portions. The real mode portion was meant to provide backward compatibility with existing operating systems such as DOS, and therefore was named CBIOS for Compatibility BIOS, whereas the ABIOS for Advanced BIOS provided new interfaces specifically suited for multitasking operating systems such as OS2. User interfaceeditThe first commercial licensing of CPM took place in 1. Digital Systems and Omron of America for use in their intelligent terminal, and with Lawrence Livermore Laboratories where CPM was used to monitor programs in the Octopus network. Little attention was paid to CPM for about a year. In my spare time, I worked to improve overall facilities . By this time, CPM had been adapted for four different controllers. In 1. 97. 6, Glenn Ewing approached me with a problem Imsai, Incorporated, for whom Glenn consulted, had shipped a large number of disk subsystems with a promise that an operating system would follow. I was somewhat reluctant to adapt CPM to yet another controller, and thus the notion of a separated Basic IO System BIOS evolved. In principle, the hardware dependent portions of CPM were concentrated in the BIOS, thus allowing Glenn, or anyone else, to adapt CPM to the Imsai equipment. Imsai was subsequently licensed to distribute CPM version 1. IMDOS.   Gary Kildall3The BIOS of the original IBM PC XT had no interactive user interface. Error codes or messages were displayed on the screen, or coded series of sounds were generated to signal errors when the power on self test POST had not proceeded to the point of successfully initializing a video display adapter. Options on the IBM PC and XT were set by switches and jumpers on the main board and on peripheral cards. Starting around the mid 1. BIOS ROM to include a BIOS configuration utility BCU9 or BIOS setup utility, accessed at system power up by a particular key sequence. This program allowed the user to set system configuration options, of the type formerly set using DIP switches, through an interactive menu system controlled through the keyboard. In the interim period, IBM compatible PCsincluding the IBM ATheld configuration settings in battery backed RAM and used a bootable configuration program on disk, not in the ROM, to set the configuration options contained in this memory. The disk was supplied with the computer, and if it was lost the system settings could not be changed. The same applied in general to computers with an EISA bus, for which the configuration program was called an EISA Configuration Utility ECU. A modern Wintel compatible computer provides a setup routine essentially unchanged in nature from the ROM resident BIOS setup utilities of the late 1. Also, when errors occur at boot time, a modern BIOS usually displays user friendly error messages, often presented as pop up boxes in a TUI style, and offers to enter the BIOS setup utility or to ignore the error and proceed if possible. Instead of battery backed RAM, the modern Wintel machine may store the BIOS configuration settings in flash ROM, perhaps the same flash ROM that holds the BIOS itself. OperationeditWhen we failed to produce an operating system in a timely manner, Glenn started talking with Gary about CPM . It took several months of twisting Garys arm to get Gary to port it to the 8. The final success came when Glenn talked Gary into just separating the IO from the rest of it, with Glenn promising to re write the IO module for the IMSAI 8. So CPM on the IMSAI was a joint effort between Glenn and Gary. Joe Killian7System startupeditGlenn . Gary, and he started twisting Garys arm. He said, Hey Gary, why cant we run this in this IMSAI The IOs all different, wont run. But Glenn persists and finally makes a deal with Gary. He says, Okay Gary, if you split out the IO, Ill write the BIOS, basic IOs system, and Glenn named it then. Well split it out separately. Ill write that part, as long as you can make a division in the program there. And he got Gary to do that and Glenn put those two pieces together and was running Garys CPM on an IMSAI. How to Update CPU Microcode in an AMI BIOSIn this guide, well show you how to update or add new CPU microcode to an AMI BIOS. If you have an Award or Phoenix BIOS, check out this guide instead. Note This information has only been tested with LGA 7. LGA 7. 75 BIOS files, so if you have a newer motherboard especially UEFI ones, it probably wont work. Why would you want to do this Updating the microcode is helpful if You did the LGA 7. MOD, and your Xeon is not working as expected or is missing functionality, such as Compare. Exchange. 12. 8, Speedstep, SSE 4. VT X. Your BIOS doesnt support a newer processor that you want to run. The microcode for your processor is old and may be buggy. Disclaimer. Theres an element of risk just flashing a normal BIOS, and especially when you start modifying it, so please attempt this mod at your own risk and only if youre experiencing some problem. We highly recommend that you dont flash the modified BIOS unless youve verified the microcode was added correctly. If you accidentally remove the microcode that your processor needs, your system may fail to boot. We are not responsible if your system is damaged while attempting this. Things youll need. Step 1 Download the microcode for your platform Desktop LGA 7. LGA 7. 75 microcode. If youre trying to add LGA 7. Xeon support to an LGA 7. It will allow you to not only add the LGA 7. Xeon microcode to your BIOS, but you can also update your processors similar LGA 7. Contains microcode for all Core 2 Duo and later desktop processors no Pentium 4 or mobile supportContains microcode for all LGA 7. Xeon processors except older Pentium 4 based 5. Desktop LGA 7. 75 microcode. Contains microcode for all Core 2 Duo and later desktop processors no Pentium 4 or mobile support Mobile LGA 7. Contains microcode for all Core 2 Duo and later mobilelaptop processors no Pentium 4 or desktop support LGA 7. Contains microcode for all the LGA 7. Xeon processors mentioned earlier no LGA 7. Step 2 Look up the CPUID for your processor. Youll need the CPUID to update the right microcode how to get the CPUID. What if I cant find the CPUID for my processor You can just update all of the microcodes. Step 3 Set aside the microcode files for your processors CPUIDNote If your CPUID ends in an h and you dont see a microcode with an h on the end, just ignore the h because it isnt actually part part of the CPUID. That just means its a hexadecimal number. When you unzip the microcode file, youll see a bunch of individual microcode files that have filenames like this cpu. Heres what the different parts of the filename mean cpu. A is the CPUID that is supported by this microcodeplat. This tells which sockets are supported by the microcode. LGA 7. 71 microcodes have a 4, 4. Desktop LGA 7. 75 has a 1, 1. And for mobile LGA 7. A0ver. 00. 00. 0a. Which microcode files should I set aside Youll want to set aside all of the microcode files with your processors CPUID. There should be at least one of these for each platform, and you should go ahead and update the microcode for all of the platforms that you want your motherboard to support. Example. So for our E5. E0 stepping SLBBM with a CPUID of 1. A, here are the LGA 7. LGA 7. 71 microcode files with a CPUID of 1. A cpu. 00. 01. 06. If you have that processor and want to add the LGA 7. LGA 7. 75 microcode which is recommended, youd want to set aside both of these files. Step 4 Open your BIOS in MMTOOL by using the Load Rom button. Note MMTOOL will only open BIOS files that end in. ROM, so if yours doesnt, just rename it to. ROM for now. Having trouble finding the BIOS rom file that you need to MOD If your BIOS is in an. EXE format. Youll need to first extract it with an unzipping program like 7 Zip. Then look for a file that ends in. BIN,. ROM, or possibly something else like a number. LGA 7. 75 BIOSes are usually around 1. KB in size, so look for a file about that size. You can also try to open the file in MMTOOL. If it isnt the right file, MMTOOL will let you know. How to extract the actual BIOS from a Dell. EXE file. Execute the following command from a DOS command prompt window Dell. Bios. Filename. exe writeromfile. This should extract the actual BIOS file to the same directory. When youre done modding the BIOS, you can use a program called AFUDOS. EXE to flash a Dell AMI BIOS. Step 5 Click the CPU PATCH tab to access the microcode area of the program. Youll then see a list of all of your current microcodes. Step 6 If youre updating your old microcode, delete all of the old microcodes that match your processors CPUIDNote MMTOOL only shows the last 4 characters of the CPUID, so dont let that throw you off. Driver Of Hp Laserjet P1108. Select the option Delete a Patch DataClick the microcode you want to delete. Click the Apply button. If your Xeons CPUID is 1. A, then delete all of the microcode entries with a CPUID of 0. A there may be more than one due to different platform types. Step 7 Insert the new microcodes. Select the option Insert a Patch DataClick browse and select the microcode you want to insert. Click the Apply button. Do this for all of the microcode files that have your processors CPUID. You should have set these aside in an earlier step. What should I do if Im getting an error message that there isnt enough room for the microcode Youll need to delete some of the old microcodes to make room. Just make sure you keep the microcode for your old processor in case you ever need to reinstall it. The microcodes with a CPUID of 0. Pentium 4 and Celerons, so those are usually safe to delete. You can also search for the CPUID on cpu world to find out which processors use that CPUID. Step 8 Click Save ROM as. BIOSStep 9 Verify that the microcode was added correctly. Go ahead and close MMTOOL, reopen it, and load your modified BIOS file, which you saved in the previous step. Navigate to the CPU Patch tab again, and make sure all of the microcodes that you added earlier are shown and that the date on them is from 2. Intel last updated them. You should also check to make sure no old microcode for your CPUID is present. If it is, youll need to go back and delete it. Otherwise, your system may use the old microcode instead of the new ones we just added. Step 1. 0 Update your BIOS using the modified ROM file that you just created. You should be able to update it the same way youd update a normal BIOS. Im not sure how to update my BIOS. The method for updating your BIOS is different for each motherboard manufacturer. With some, you can simply put the BIOS file on a USB key, reboot and enter the BIOS, and update it from there. Others may have a BIOS updating program that you can run from within Windows. And in some cases, you may need to put the BIOS on a bootable DOS USB key, CD, or DVD and update it from a command prompt. If theres a Windows or DOS BIOS updating program, it will usually be included with the BIOS. BIOS. If you dont see it, check the downloads section, FAQ section, or support section. If all else fails, try searching Google for your motherboards model and update BIOS or something like that. Step 1. 1 Do a FULL BIOS reset use the 3 pin motherboard reset jumper, and then load the default BIOS settings on the first startupHow to fully reset your BIOS.
