IDE Primary/Secondary Master/Slave UDMA Ultra DMA-33/66 implementation is possible only if the IDE hard drive supports it and the operating environment includes a DMA driver (Windows 95 OSR2 or a third-party IDE bus master driver). If your hard drive and your system software both support Ultra DMA-33/66, select Auto to enable BIOS support. The Choice: Auto, Disabled. USB Controller Select Enabled if the system contains a Universal Serial Bus (USB) controller. The Choice: Enabled, Disabled.
Watchdog Timer Unit Select the Watchdog Timer unit. The choice: Second, Minute. 4.9 Power Management Setup The Power Management Setup allows the user to configure the system to the most effective energy save.
Power Management This category allows the user to select the type (or degree) of power saving related to the following modes: 1. HDD Power Down 2. Doze Mode 3. Suspend Mode There are four selections for Power Management, three of which have fixed mode settings. Disable (default) Min. Power Saving Max. Power Saving User Defined No power management. Disables all four modes • Minimum power management • Doze Mode = 1 hr. • Standby Mode = 1 hr. • Suspend Mode = 1 hr. • HDD Power Down = 15 min.
HDD Power Down When enabled and after the set time of system inactivity, the hard disk drive will be powered down while all other devices remain active.

PM EVENTS PM events are I/O events whose occurrence can prevent the system from entering a power saving mode or can awaken the system from such a mode.
4.10 PnP/PCI Configuration Setup This section describes configuring the PCI bus system. PCI stands for Personal Computer Interconnect. It is a system which allows I/O devices to operate at speeds nearing the speed the CPU itself uses when communicating with its own special components. This section covers some specific technical settings and it is strongly recommended that only experienced users should make any changes to the default settings.
IRQ3/4/5/7/9/10/11/12/14/15 assigned to This item allows the user to determine the IRQ assigned to the ISA bus and is not available to any PCI slot. Legacy ISA for devices compliant with the original PC AT bus specification, PCI/ISA PnP for devices compliant with the Plug and Play standard whether designed for PCI or ISA bus architecture.

4.14 Supervisor/User Password Setting The user can set the password for either supervisor or user, or for both of them. Supervisor password: for entering and changing the settings of the system User password: for just entering the system but does not have the privilege to change any settings of the system If this function is enabled, the following message will appear to guide the user to create a password. ENTER PASSWORD: Type the password, up to eight characters in length, and press .
4.15 Exit Selecting Save & Exit Setup Pressing on this item asks for confirmation: Save to CMOS and EXIT (Y/N)? Y Pressing “Y” stores the selections made in the menus in CMOS – a special section of memory that stays on after the system has been turned off. When the computer reboots again, the BIOS configures the system according to the Setup selections stored in CMOS.
Appendix A Watchdog Timer The Watchdog Timer is provided to ensure that standalone systems can always recover from catastrophic conditions that cause the CPU to crash. This condition may have occurred by external EMI or a software bug. When the CPU stops working correctly, hardware on the board will either perform a hardware reset (cold boot) or a Non-Maskable Interrupt (NMI) to bring the system back to a known state.

Appendix C How to Upgrade a New BIOS Note: Before flashing BIOS, please enable the item “FLASH BIOS” in BIOS setting. The user can install an upgrade BIOS for the SAGP-845EV download from the manufacturer’s web site (http://www.ieiworld.com). New BIOS may provide support for new peripherals, improvements in performance or fixes to addressed known bugs. BIOS Update Procedure: 1. Make a boot disk.
new BIOS file WITHOUT a warning prompt. A simple file name for saving the old BIOS to is OLDBIOS.BIN. 9. Your second option, in sequence, will be whether you want to flash your BIOS. Enter Y (for "yes"). Note: This is the critical step. Once you kit the enter key, do NOT touch the keyboard, the reset button, or power switch while the flashing is in progress. There will be bar progressing across the screen while the flashing is progressing. 10.
Appendix D AGP Slot This IPC CPU Card has an Accelerated Graphics Port (AGP) slot that supports +1.5V AGP card. When you buy an AGP card, make sure that you ask for one with +1.5V specification. Note the notches on the card golden fingers to ensure that they fit the AGP slot on your ICP CPU card.
