| The system BIOS and the information required to configure it are stored on a | Complementary Metal-Oxide Semiconductor (CMOS) chip |
| CMOS is a battery-powered storage chip located | on the system board. |
| The CMOS chip has rewritable memory since the configuration data can be | changed or updated as the components or devices in the computer are changed. |
| the CMOS allows the | BIOS upgrade |
| Configuration of the BIOS on a computer is called the | BIOS setup or CMOS setup |
| the BIOS scans the system at boot time and compares what it finds against | settings in CMOS, it must be properly configured in order to avoid errors. |
| Built into the BIOS is a comprehensive self-diagnostic routine called the | Power-On Self-Test (POST), which checks the internal system circuits at boot-up and gives error codes |
| In order for the BIOS to have meaningful diagnostics and error checking, the | internal components and devices of a newly assembled computer need to be configured properly in CMOS. |
| CMOS refers to the type of integrated | circuit that is used to store the BIOS configuration |
| pressing the delete key during the opening boot sequence provides access to the | BIOS on some computers |
| early in the startup process the BIOS places a prompt on the display to tell the user that | the CMOS Setup utility can be accessed by pressing a special key or a given key combination |
| The CMOS setup access keys and key combinations include the ESC key, the | DEL key, the F2 function key, and the CTRL-ALT-ESC key combination. |
| The values input through the BIOS setup are stored in | the system CMOS configuration registers |
| On the CMOS setup screen the cursor on the screen can be moved from item to item using | the keyboard's cursor control keys. |
| On the CMOS setup screen the fields available for entering configuration data commonly found are | Date, Time, Hard Disks, Drive A, Drive B, Video, and Halt On. |
| IDE controllers can have up to two | hard drives or one hard drive and another IDE device such as a CD-ROM attached |
| Setting the drive type to Auto allows the BIOS to | auto-detect and configure the hard drives so that this information does not have to be entered manually. |
| In the CMOS setup the video adapter standard since 1990 has been | EGA/VGA |
| all the video adapters since 1990 will support the | basic VGA BIOS instructions built into the system BIOS. |
| The Halt On in the Standard CMOS screen allows a specific system response to errors | so error problems can be reported before they corrupt data |
| The BIOS Features setup screen is where the system hardware can be | fine-tuned for optimal performance |
| On the BIOS Features setup screen unless there is a good reason to change the settings | most of the features should be left at their default settings |
| the system boot order to be specified on | the BIOS Features setup screen |
| The boot sequence set to A, C means | System first searches for a master boot record on the floppy dis then the harddrive |
| The boot sequence set to C, A means | System first searches for a master boot record on the hard drive then the floopydrive |
| The boot sequence set to C, CD-ROM, Ameans | System first searches for master boot boot record on hard disk, the the CD-ROM, and lastly the floppy drive |
| The chipset controls the | memory, system cache, processor, and I/O buses |
| Settings found in Power Management Setup screen can be enabled in order to | control devices going into sleep or suspend mode. |
| , it is usually recommended to disable the feature choice "Power Management" because some software applications and operating systems may | not deal well with components being powered down, as the software may no longer recognize such devices properly. |
| The PnP/PCI Configuration screen contains the feature settings used to | control the system I/O bus and Interrupt Request (IRQ) and Direct Memory Access (DMA) allocation for ISA and PCI Plug and Play (PnP) devices. |
| When the "Resource Controlled By" setting is set by default to Automatic Configuration, the BIOS will | automatically manage the interrupts and direct memory access channels on the I/O bus for the PnP devices to avoid conflicts with any legacy (non-PnP) ISA devices. |
| When IRQs or DMAs must be manually designated for some non-conforming PnP expansion boards or adapter cards the | designated resources will have to be removed from BIOS |
| If any conflicts occur when working on the PnP/PCI Configuration Setup, be aware that the "Reset Configuration Data" feature will | clear this portion of the BIOS setup and return it to defaults upon rebooting the system. |
| Integrated peripherals typically include such devices as the | onboard floppy and hard drive controllers, USB controller, serial ports, parallel ports, and the sound card chip |
| IDE HDD Auto Detection is to be used when | the Standard CMOS Setup screen "Hard Disks" feature set to AUTO does not work |
| The IDE HDD Auto Detection allows the manual | running of the IDE auto detection program and selects the auto detection for each drive on the controller channel. |
| The two password screens that will be encountered in the BIOS setup are | User Password and Supervisor Password |
| The User Password option allows the installation of a password that will keep | the system from booting unless the proper password is entered |
| The Supervisor Password where BIOS settings are | kept standardized by computer support personnel and locked with this master password |
| The Load Setup Defaults screen | resets the BIOS setup to default settings |
| two BIOS exit options | Exit Without Saving Setup; Save and Exit Setup |
