®
Matrix Storage Technology:
• RAID 0 - data striping
• RAID 1 - data mirroring
• RAID 0+1 (or RAID 10) - data striping and data mirroring
• RAID 5 - distributed parity
Expandability
For system expansion, the Desktop Board provides the following expansion slots:
• One PCI Express 2.0 x16 connector (compatible with PCI Express 1.1 add-in cards)
• Two PCI Express 1.1 x1 connectors

BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the
PCI/PCI Express auto-configuration utilities, and the video BIOS. The BIOS is stored in
the Serial Peripheral Interface (SPI) Flash device.
The BIOS can be updated by following the instructions in Chapter 3.
ATA Auto Configuration
If you install a Serial or Parallel ATA device 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 an ATA 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 or PCI Express add-in card.
