devices within a category (such as to boot from IDE hard drive instead of SCSI), or to permanently change the boot order, you will have to enter SETUP and change the boot options.
If any errors are detected up to this point they will now be displayed on the screen along with the following prompt to direct further actions. Pressing F1 will ignore the errors and continue with the boot process. The F2 key can be pressed to enter the ROM UTILITIES and possibly resolve any configuration error that may have been made.
Press F2 to Run SETUP
Press F1 to load default values and continue
If the F2 key was not pressed, and no errors were detected, the system summary screen will be displayed. After 10 seconds or upon a key press the BIOS will attempt to boot the installed operating system.
The System BIOS is compatible with the Plug and Play Specification Version 1.0A. The two areas that are addressed by the System BIOS are Resource Management and Runtime Services.
Resource Management provides the ability to manage the fundamental system resources, which include DMA, Interrupt Request Lines (IRQs), I/O and Memory addresses. These resources, termed system resources, are in high demand and commonly are over allocated or allocated in a conflicting manner in ISA systems, leading to system configuration failures.
The resource manager takes on the responsibility for configuring Plug and Play cards, as well as system board devices during the power up phase. After the
Runtime Services provide a mechanism whereby a Plug and Play operating system, such as Windows 2000, may perform resource allocation dynamically at runtime. The operating system may directly manipulate the configuration of devices that have traditionally been considered static.
