Storage
The Mobile Board supports two types of storage devices:
• Optical Disk Drives
• Hard Disk Drives
The Mobile Board supports two Serial ATA channels (3.0 Gb/s) via the Intel ICH9M-E,
connecting one device per channel. Two connectors are provided: one for an optical
disk drive (Figure 2, P) and one for a hard disk drive (Figure 2, N). Refer to Chapter 2
f
or instructions on how to install an optical disk drive or a hard disk drive.
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the 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.
Serial ATA Auto Configuration
If you install a Serial ATA device (such as a hard disk drive or optical disk drive) in
your notebook, 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 device. You can override the auto-configuration
options by specifying manual configuration in the BIOS Setup program.
PCI Express Auto Configuration
If you install a PCI Express mini card in your computer, the PCI Express auto-
configuration utility in the BIOS automatically detects and configures the resources
(IRQs, DMA channels, and I/O space) for that card. You do not need to run the BIOS
Setup program after you install a PCI Express mini card.
Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can
be accessed and who can boot the computer. A supervisor password and a user
password can be set for the BIOS Setup and for booting the computer, with the
following restrictions:
• The supervisor password gives unrestricted access to view and change all Setup
options. If only the supervisor password is set, pressing <Enter> at the password
prompt of Setup gives the user restricted access to Setup.
• If both the supervisor and user passwords are set, you must enter either the
supervisor password or the user password to access Setup. Setup options are then
available for viewing and changing depending on whether the supervisor or user
password was entered.
