Configuring BIOS Settings

Image
This section describes how to view and/or modify the Basic Input/Output System (BIOS) settings on the Sun Fire X4170, X4270, and X4275 Servers. The BIOS Setup utility reports system information and can be used to configure the server BIOS settings. BIOS has a Setup utility stored in the BIOS flash memory. The configured data is provided with context-sensitive Help and is stored in the system's battery-backed CMOS RAM. If the configuration stored in the CMOS RAM is invalid, the BIOS settings default to the original state specified at the factory. The following topics are covered: Using BIOS Setup Utility Menu Items BIOS Setup Screens Overview BIOS Setup Utility Menu Screens Default BIOS Power-On Self-Test (POST) Events BIOS POST F1 and F2 Errors Ethernet Port Device and Driver Naming E.1 Using BIOS Setup Utility Menu Items You can access BIOS Setup utility screens from the following interfaces: Use a USB keyboard, mouse, and VGA monitor connected d...

How does a computer work?

Image
This document has been created to give you a better understanding of how the personal computer works and what it does each time you press the power button. Powering on the computer When you first press the power button, the computer sends a signal to the computer  power supply , which converts the alternating current ( AC ) to a direct current ( DC ). This supplies the computer and its components with the proper amount of voltage and electricity. Once the computer and its components have received ample power and the power supply reports no errors it sends a signal (using  transistors ) to the motherboard and the computer processor ( CPU ). While this is happening, the processor will clear any leftover data in the memory registers and give the CPU  program counter  a F000 hexadecimal number. This number is the location of the first instruction and tells the CPU that it's ready to process the instructions contained in the basic input/output system ( BIOS ). B...

How to enter the BIOS or CMOS setup ?

Image
Because of the wide variety of computer and BIOS manufacturers over the evolution of computers, there are numerous ways to enter the  BIOS  or  CMOS  Setup. Below is a listing of most of these methods, as well as other recommendations for entering the BIOS setup. Note:  Apple, or Mac, computers do not have a BIOS and instead utilize an  EFI , which does not need to modified based on the hardware in the computer, like a BIOS. The EFI provides better integration between hardware and software for Apple computers, virtually eliminating the need for a BIOS. Note:  This document does not help if you  cannot enter the CMOS setup with password . New computers Computers manufactured in the last few years allow you to enter the BIOS setup using one of the five keys shown below during the  boot  process. F1 F2 * F10 ** Del Esc Note:  F1, F2, and F10 are all  function keys  on the top of the keyboard. * If pressin...
