Intel Server Board S815EBM1 Product Guide
✏
NOTE
Server systems that have an unshielded cable attached to a USB port might not meet FCC Class B
requirements even if no device or a low-speed USB device is attached to the cable. Use a shielded
cable that meets the requirements for a full-speed USB device.
PCI Enhanced IDE Interface
The PCI enhanced IDE interface handles the exchange of information between the processor and
peripheral devices like hard disks, and Iomega Zip
†
drives inside the server. The interface
supports:
•
Up to four IDE devices (such as hard drives)
•
PIO Mode 3 and PIO Mode 4 devices
•
Ultra UDMA/33, Ultra ATA/66, and Ultra ATA/100 protocols
•
Support for laser servo (LS-120) drives
Expansion Slots
The S815EBM1 board has three add-in board connectors.
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE
auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub.
The BIOS can be upgraded by following the instructions in Chapter 3.
PCI Auto Configuration
If you install a PCI add-in board in your server, the PCI auto-configuration utility in the BIOS
automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that
add-in board. You do not need to run the BIOS Setup program after you install a PCI
add-in board.
IDE Auto Configuration
If you install an IDE device (such as a hard drive) in your server, the IDE auto-configuration utility
in the BIOS automatically detects and configures the device for your server. You do not need to
run the BIOS Setup program after installing an IDE device.
Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can be accessed
and who can boot the server. A supervisor password and a user password can be set for the Setup
menu and for booting the server, 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.
