BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI/PCI
Express and IDE auto-configuration utilities, and the video BIOS.
Serial ATA and IDE Auto Configuration
If you install a Serial ATA or IDE device (such as a hard drive) in your computer, the auto-
configuration utility in the BIOS automatically detects and configures the device for your computer.
You do not need to run the BIOS Setup program after installing a Serial ATA or IDE device. You
can override the auto-configuration options by specifying manual configuration in the BIOS Setup
program.
PCI and PCI Express Auto Configuration
If you install a PCI/PCI Express add-in card in your computer, the PCI/PCI Express auto-
configuration utility in the BIOS automatically detects and configures the resources (IRQs, DMA
channels, and I/O space) for that add-in card. You do not need to run the BIOS Setup program after
you install a PCI/PCI Express add-in card.
