Features of the ASUS Motherboard
The ASUS P/I-P55T2P4 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 that supports auto detection of hard
drives and Plug and Play to make setup of hard drives and expansion cards
virtually automatic.
• Versatile Processor Support: Intel Pentium
®
75-233MHz (P55C-MMX
™
, P54C/
P54CS), IBM
®
/Cyrix
®
6x86-PR166+ (Rev 2.7 or later), IBM
®
/Cyrix
®
6x86MX
™
(PR166 & above), AMD-K5
™
(PR75-PR133), AMD-K6
™
(PR166-PR233).
• Intel Chipset: Features Intel's 430HX PCIset with I/O subsystems.
• Error Checking and Correcting (ECC): Using Intel's 430HX PCIset together
with parity DRAM modules can detect multi-bit memory errors and correct 1-
bit memory errors.
• Desktop Management Interface (DMI): Supports DMI through BIOS which
allows hardware to communicate within a standard protocol creating a higher
level of compatibility (see section V).
• L2 Cache: Provides the option of 0KB upgradeable to 256KB or 512KB, on-
board 256KB upgradeable to 512KB, or 512KB onboard Pipelined Burst SRAM.
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, 32MB, or 64MB to form a memory size between 8MB to 256MB. Sup-
ports both Fast Page Mode (FPM) 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 a 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 compatibility informa-
tion, 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
from COM2 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 exter-
nal card. The Japanese "Floppy 3 mode" (3.5" 1.2MB) floppy standard is
also supported.
