II. FEATURES
Features of This Motherboard
The P/I-P55TP4N is carefully designed for the demanding PC user who
wants a great many features in a small package. This motherboard:
• Easy Installation: Is equipped with BIOS supports auto detection of
hard drives and Plug and Play to make setup of hard drives and expan-
sion cards virtually automatic.
• Multi-Speed Support: Supports one 75-166MHz Pentium CPU on a
ZIF Socket 7.
•
Intel Chipset: Features Intel's 430FX PCIset with I/O subsystems.
• Desktop Management Interface (DMI): Supports DMI through BIOS
which allows hardware to communicate within a standard protocol cre-
ating a higher level of compatibility.
• L2 Cache: Provides the option of 0KB upgradeable to 256KB or
512KB, or onboard 256KB Pipelined Burst SRAM upgradeable to
512KB. Upgrades are made through a Synchronous SRAM cache
module. (See page 14 for compatible cache modules.)
• Versatile DRAM Memory Support: Supports 72-pin SIMMs of 4MB,
8MB, 16MB, or 32MB to form a memory size between 8MB to 128MB.
Supports both Fast Page Mode and Extended Data Output (EDO)
SIMMs.
•
ISA and PCI Expansion Slots: Provides three 16-bit ISA slots, three
32-bit PCI slots, and one PCI/MediaBus 2.0 which allows the use of
either an standard PCI card or the ASUS MediaBus Card.
• ASUS MediaBus Rev 2.0: Features an expansion slot extension shared
with PCI Slot 4 for an optional high-performance expansion card which
includes two functions in one easy-to-install card. (For revision com-
patibility information, please refer to page 18.)
• Super Multi-I/O: Provides two high-speed UART compatible serial
ports and one parallel port with EPP and ECP capabilities. UART2
can also be directed to the Infrared Module for wireless connections.
Two floppy drives of either 5.25" or 3.5" (1.44MB or 2.88MB) are also
supported without an external card. The Japanese "Floppy 3 mode"
(3.5" 1.2MB) floppy standard is also supported.
