Advanced/ZP Technical Product Summary • Page 10
• The Flash BIOS can be updated from a file on a disk;
• The current BIOS code can be copied from the Flash EEPROM to a disk file as a backup in the event that an
upgrade cannot be successfully completed; or
• The BIOS in the Flash device can be compared with a disk file to ensure the system has the correct BIOS version.
The upgrade utility ensures the upgrade BIOS extension matches the target system to prevent accidentally installing a
BIOS for a different type of system. A recovery jumper is provided to allow recovery in the unlikely event of an
unsuccessful BIOS upgrade. The jumper forces the ROM decode to access a 8 KB block of write protected recovery code
in the Flash device.
SETUP UTILITY
The ROM-based Setup utility allows the configuration to be modified without opening the system for most basic changes.
The Setup utility is accessible only during the Power-On Self Test, POST, by pressing the <F1> key after the POST
memory test has begun and before boot begins. A prompt may be enabled that informs the user to press the <F1> key to
access Setup. A switch on the baseboard can be set to prevent user access to Setup for security purposes. Setup options are
detailed in the BIOS appendix.
PCI AUTO-CONFIGURATION
The PCI auto-configuration utility operates in conjunction with the system Setup utility to allow the insertion and
removal of PCI cards to the system without user intervention. When the system is turned on after adding a PCI add-in
card, the BIOS automatically configures interrupts, DMA channels, I/O space, and other parameters. The user does not
have to configure jumpers or worry about potential resource conflicts. Because PCI cards use the same interrupt resources
as ISA cards, the user must specify the interrupts used by ISA add-in cards in the Setup utility. The PCI Auto-
Configuration function complies with version 2.10 of the PCI BIOS specification.
ISA PLUG & PLAY
The BIOS incorporates ISA Plug and Play capabilities conforming to version 1.0a of the Plug-n-Play specification. This
will allow auto-configuration of Plug and Play ISA cards, and resource management for legacy ISA cards, when used in
conjunction with the ISA Configuration Utility (ICU).
SHADOW MEMORY
Memory from C8000-DFFFF is not shadowed. This is a change from previous Intel products using AMI BIOS. This may
have a slight adverse affect on the performance of some non-Plug and Play ISA cards. All or part of this area may be used
as shared ISA memory if needed. Video BIOS located from C0000-C7FFF is shadowed to boost performance.
POWER MANAGEMENT
The Advanced/ZP will enable you to have an Energy Star compliant system through its Advanced Power Management
resources. The Advanced/ZP BIOS supports power management via System Management Mode (SMM) interrupts to the
CPU and Advanced Power Management (APM v1.1). In general, power management capabilities will allow the system to
be put into a power managed Stand By state. This can be accomplished by pressing the sleep/resume button on the front
of the chassis, entering an user configured hot-key sequence on the keyboard, or by the expiration of a hardware timer
which detects system inactivity for a user-configurable length of time. While in the Stand By state, the Advanced/ZP
baseboard reduces the system power consumption to Energy Star levels by utilizing the power saving capabilities of the
Pentium
Processor, spinning down the IDE hard drive, and turning off an Energy Star rated monitor. Add-in cards
supplied with APM-aware drivers can also be put into a power managed state for further energy savings. The ability to
respond to external interrupts is fully maintained while in Stand By mode allowing the system to service requests such as
in-coming FAX’s or network messages while unattended.
FLASH LOGO AREA
Advanced/ZP supports a 4 KB programmable FLASH user area located at EC000-ECFFF. An OEM may use this area to
display a custom logo. The BIOS accesses the user area at several points during the boot up sequence.
