✏ 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 at the password prompt of Setup gives the user restricted access to Setup. 14 Intel Server Board S815EBM1 Product Guide
