IDE Auto Configuration

If you install an IDE device (such as a hard drive) in your computer, the IDE 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 IDE device. You can override the auto- configuration options by specifying manual configuration in the BIOS Setup program.

To use ATA-66/100 features, the following items are required:

An ATA-66/100 peripheral device

An ATA-66/100 compatible cable

ATA-66/100 operating system device drivers

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 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.

Setting a user password restricts who can boot the computer. The password prompt is displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, you can enter either password to boot the computer.

LAN Subsystem (Optional)

The optional Intel 82562ET (with the Intel 82801BA ICH2) provides a Fast PCI LAN subsystem providing both 10Base-T and 100Base-TX connectivity. The Intel 82562ET provides the following functions:

Basic 10/100 Ethernet LAN connectivity

Supports RJ-45 connector with status indicator LEDs

Programmable transit threshold

Configurable EEPROM that contains the MAC address
