Introduction The Intel Advanced/ZP baseboard features the Pentium processor in a Baby-AT form factor with integrated I/O. Advanced/ZP baseboards are focused on providing the best possible performance at the lowest possible price for mainstream desktop computers. Advanced/ZP is a flexible baseboard which is available with the 75 MHz, 90 MHz, 100 MHz, or 120 MHz Pentium processor.
BASEBOARD DESIGN EXCEPTIONS BASEBOARD DIMENSIONS The Advanced/ZP is 3.0" shorter than the Baby-AT standard. The shorter board length may require some chassis to be modified to add additional mounting holes. MOUNTING HOLE PLACEMENT The mounting holes located in the bottom left and right corners of Figure 1 are pseudo Baby-AT standard and are available in many, but not all, Baby-AT compatible chassis. FRONT PANEL CONNECTORS There is no front panel connector on the baseboard for a Turbo/Deturbo switch.
Board Level Features AB C D E F A − Two PCI IDE interfaces B − National 87306 I/O controller C − Primary power connector D − Four SIMM sockets (two banks) E − 82438FX Triton Data Path (TDP) F − Parallel port connector G − Floppy drive connector H − 256KB Secondary cache I − 82437FX Triton System Controller (TSC) J − Socket 5 Pentium processor socket K− CPU voltage regulator L − Front Panel I/O connectors M − Configuration switch block N − 82371FB PCI ISA/IDE Accelerator (PIIX) O − Battery for the Real-time
SYSTEM MEMORY The Advanced/ZP baseboard provides four 72-pin SIMM sites for memory expansion. The sockets support 1M x 32 (4 MB), 2M x 32 (8 MB), 4M x 32 (16 MB), and 8M x 32 (32 MB) single-sided or double-sided SIMM modules. Minimum memory size is 8 MB and maximum memory size, using four 8M x 32 SIMM modules, is 128 MB. For external CPU speeds of less than 60 Mhz (used with 75, 90 and 120 Mhz processors) memory timing requires 70 ns fast page devices or, for higher performance, 70 ns EDO DRAM.
PERIPHERAL COMPONENT INTERCONNECT (PCI) PCISET The Intel Triton 82430FX PCIset consists of the 82437FX Triton System Controller (TSC), two 82438FX Triton Data Path (TDP) devices, and one 82371FB PCI ISA/IDE Accelerator (PIIX) bridge chip.
IDE SUPPORT The Advanced/ZP baseboard provides two independent high performance bus-mastering PCI IDE interfaces capable of supporting PIO Mode 3 and Mode 4 devices for up to 16 MB/sec transfers. Support for ATAPI devices is provided in the system BIOS. The system BIOS also supports Logical Block Addressing (LBA) and ECHS on both IDE interfaces. When used in conjunction with a special driver the IDE interface operates as a PCI bus master for optimum performance in a multi-tasking environment.
the CMOS RAM values can be cleared to the system defaults by using a configuration switch on the baseboard. Appendix B lists switch and jumper configurations. An external coin-cell style battery provides power to the RTC and CMOS memory. The battery has an estimated lifetime of seven years and is socketed for easy replacement. Refer to Appendix A for battery replacement details. IRDA (INFRARED) SUPPORT Serial port 2 can be configured to support an IrDA module via a 5 pin header connector.
•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.
SECURITY FEATURES ADMINISTRATIVE PASSWORD The administrative password protects several sensitive Setup options from being viewable to a user unless the password is entered. These sensitive fields are viewable unless the administrative password is set. BIOS PASSWORD A BIOS password feature provides security during the boot process. A password can be entered using the Setup utility, and will be required on boot up before normal operation of the system can commence.
Figure 3. Front Panel Connectors Sleep/Resume This two pin header, when connected to a momentary switch, can be used to put the system into a power managed state (standby) that will reduce the system’s power consumption. If the system is in Stand By mode and the switch is pressed, the system will instantly “wake up” or Resume full system activity.

Appendix A − User-Installable Upgrades SYSTEM MEMORY Table A-1 shows the possible memory combinations. The Advanced/ZP will support both Fast Page DRAM or EDO DRAM SIMMs, but they cannot be mixed within the same memory bank. If Fast Page DRAM and EDO DRAM SIMMs are installed in separate banks, each bank will be optimized for maximum performance. Parity generation and detection is NOT supported. SIMM requirements are Fast Page Mode or EDO DRAM, 60 nS or 70 nS, with tin-lead connectors.
Appendix B − Jumpers and Switches Figure B-1. Jumper locations and settings (default settings shown) EXTERNAL CPU CLOCK SPEED (50/60/66 MHZ) - SWITCHES 7 & 8 This jumper sets the CPU's external operating frequency at 50, 60, and 66 MHz.. Default setting is 50 MHz. Frequency 50 MHz 60 Mhz 66 MHz Switch 7 OFF ON OFF Switch 8 OFF OFF ON Table B-1. External CPU Speed Switches INTERNAL CPU BUS CLOCK SPEED - SWITCH 6 Sets the internal processor speed to either 3/2 or 2 times the external CPU clock speed.
PROCESSOR VOLTAGE REGULATION - SWITCH 2 Sets the output of the on-board voltage regulator. The switch settings are OFF = VR, and ON = VRE. The VR voltage specification requires a voltage range of 3.3-3.465 Volts DC, while the VRE specification requires a voltage range of 3.453.6V. Pentium processors currently available that do not require the VRE voltage specification should use the VR setting.

Appendix H − BIOS Recovery The Advanced/ZE incorporates the AMIBIOS in a Flash memory component. Flash BIOS allows easy upgrades without the need to replace an EPROM. The upgrade utility fits on a floppy diskette and provides the capability to save, verify, and update the system BIOS. The upgrade utility also provides the capability to install alternate languages for BIOS messages and the SETUP utility.
Appendix I − Error messages and Beep Codes Errors can occur during POST (Power On Self Test) which is performed every time the system is powered on. Fatal errors, which prevent the system to continue the boot process, are communicated through a series of audible beeps. Other errors are displayed in the following format: ERROR Message Line 1 ERROR Message Line 2 For most displayed error messages, there is only one message. If a second message appears, it is "RUN SETUP".
