On PCs, the BIOS (Basic Input/Output System) is updatable computer firmware designed to initialize the computer during start prior to handing control to the operating system. Spellforce serial number problem worksheet. Due to the sensitive nature of the system settings controlled by the BIOS, a password can be set by either the computer manufacturer or the end-user. Some of the most common BIOS producers include AMI, AWARD, IBM, and Phoenix with many manufacturers making their own changes to the firmware prior to selling a computer on the open market.

The common methods to reset BIOS password include: Generating a BIOS password using a hash code, entering a backdoor BIOS password, reset the BIOS password using software, reset the BIOS password using hardware, and resetting the BIOS password with vendor specific solutions. How Does the BIOS Work? The computer BIOS is the first programming code executed by a PC when the machine is rebooted or turned on. The computer firmware conducts a power-on self-test of the system which is responsible for identifying system hardware and initializing components such as the CPU, hard drive(s), RAM, video card, mouse, and keyboard. Once the initialization task is complete, the BIOS checks the boot devices in order of configured preference (traditional default setting is the computer’s hard drive). The boot loader software is executed by the BIOS once located, and control of the computer is then passed to the operating system.

Functionality that can be changed by the end-user through the BIOS user interface (UI) include setting the system clock, enabling or disabling system hardware, configuring hardware, enabling or setting passwords, and choosing the order of boot devices. Although the BIOS was originally stored on a ROM (read only memory) chip on the computer’s motherboard, today’s computers will store the firmware in flash memory or EEPROM chips that can be updated after the computer has been sold.

Once Intel started producing chips for use on non-PC hardware such as Macintoshes, a successor to the legacy BIOS system was required and is called the Extensible Interface (EFI). Although EFI provides a number of improvements over the traditional BIOS, it has not yet gained market dominance on PC’s. Is There a BIOS on Mac OS X? Prior to the production of Mac computers using x86 or Intel chips during the later portion of the 2000’s and their use of EFI, OpenFirmware was the BIOS equivalent on all Macintosh computers. Provides similar functionality on a Mac as the BIOS and EFI do on other computing systems.

It conducts tasks such as locating attached or installed hardware and uses environment variables to direct the boot process for the Mac. To access the interface for OpenFirm, press the power button on the mac for about 10 seconds. While pressing the power button, simultaneously depress the “CMD,” “OPT,” “O,” and “F” keys once you hear an audible “chime.” Once you are done with the required modifications in OpenFirmware, exit the interface by typing “bye”, “boot”, or “mac-boot” (depends on the version of Mac computer you are using) followed by pressing the “return” key. How to Rest a BIOS Password By Using a Hash Code A lot of the major computer manufacturers use a master password generated from a hash code to reset the master BIOS password. This hash code is normally calculated from a unique equipment identifier such as the Serial Number, Service Tag, System ID, or Express Service Code. On many brands of computer, the identifying code will be displayed after the BIOS password has been entered incorrectly three times in a row.

On other brands, it may be printed on the computer. On some HP models of computer, the hash code will only display if the “F2” or “F12” keyboard function key is press prior to entering the incorrect password a third time. A free service provided by Tech FAQ (other websites will charge you) is our BIOS password generation tool. The tool is designed to make a BIOS password that will work on many computer brands to include: Compaq, Dell, Fujitsu-Siemens, HP, Samsung, and Sony models. The tool has also worked for many white-label PC’s running Phoenix or Insyde BIOS. Tech-FAQ.com recommends end users that desire to reset the BIOS password for their respective computer try the hashcode generator before paying another company money to conduct the same task.

Many times, third party companies will simply charge individuals upwards of $40 USD to obtain the same information provided for free here. Hi, my Samsung NP305E5A A08US gave various system disabled numbers and each time I entered those numbers I got no response from the Password Generator. Than I noticed that the disable number had 18 numbers (ten numbers and eight zeros), which I eliminated two zeros and each time I disabled the laptop and entered those numbers in the Generator, minus two zeros, I got this number: 0000,aa, But when I restart the laptop and the system code box appears, I enter the number above but the commas won’t enter into the code. Therefore, my question is whether leaving the two zeros of the number matters? And secondly, how can I get the commas to get recognized in the code??????
