II. FEATURES
Features of This Motherboard
The ASUS P/I-XP55T2P4 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.
•Multi-Processor/Multi-Speed Support: Supports one Pentium (75-200MHz), Cyrix P166+ (Rev 2.7 or later), or AMD-K5(PR75-100MHz) (See page 11).
•Intel Chipset: Features Intel's 430HX PCIset with I/O subsystems.
•Error Checking and Correcting (ECC): Using Intel's 430HX PCIset and parity DRAM modules can detect multi-bit 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)
•ATX Power Connector: Has a single easy-to-install connector for 3.3V, 5V, 12V, and a new soft-power control. (Requires an ATX power supply)
•L2 Cache: Provides the option of 0KB upgradeable to 256KB or 512KB, onboard 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. Supports both Fast Page Mode (FPM) and Extended Data Output (EDO) SIMMs. (see page 12)
•ISA and PCI Expansion Slots: Provides four 16-bit ISA slots, three 32-bit PCI slots, and one PCI/MediaBus 2.0 which allows the use of either an stan- dard 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 infor- mation, 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 external card. The Japanese "Floppy 3 mode" (3.5" 1.2MB) floppy standard is also supported.
•NCR SCSI BIOS: This motherboard has firmware that supports the optional ASUS PCI-SC200 SCSI controller cards.
