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. The processor is complemented by a standard 256 KB asynchronous SRAM second level write-back cache and support for up to 128 MB of Fast Page or EDO DRAM. A Pentium OverDrive® socket (Socket 5) provides access to future performance enhancements.

The Advanced/ZP baseboard offers outstanding I/O capabilities starting with the full set of I/O, including a floppy drive interface, dual channel PCI local bus IDE interfaces, two serial ports with FIFOs, an EPP/ECP capable parallel port, and an infrared (IrDA) port. Two dedicated PCI local bus slots, and one shared PCI/ISA slot, provide a high bandwidth data path for functions such as graphics that have a high data throughput requirement. The integrated Bus Mastering capable PCI IDE controller provides two high performance IDE interfaces for hard drives and CD-ROMs. Bus mastering enhances the performance in multi-tasking environments such as Windows* 95. The Advanced/ZP baseboard also provides three dedicated ISA connectors and one shared PCI/ISA connector. There is one PCI full length capable slot, and three ISA full length capable slots.

In addition to superior hardware capabilities, features like Windows 95-ready Plug and Play and Advanced Power Management (APM) with application restart are provided by software available from Intel for the Advanced/ZP platform.

The Advanced/ZP baseboard provides the foundation for cost effective, high performance, highly expandable platforms which deliver the latest in CPU and I/O technology.

Although the Advanced/ZP will support CGA emulation by VGA cards, it will not support CGA cards.
