SIMM sockets to support 4–64MB 72-pin Fast Page Mode (FPM) or Extended
Data Out (EDO) memory modules up to 256MB. SIMMs and DIMMs cannot be
used at the same time.
•Easy Installation: Incorporates BIOS that supports autodetection of hard disk
drives, PS/2 mouse, and Plug and Play devices to make setup of hard disk drives,
expansion cards, and other devices virtually automatic.
•Dual Power Supply: Includes both AT and ATX power connectors onboard to
support an AT or ATX power supply with soft-on/soft-off features.
•ISA and PCI Expansion Slots: Provides two 16-bit ISA slots, three 32-bit PCI
slots, and one PCI/ISA shared slot for either a PCI or ISA card.
•Super Multi-I/O: Provides two high-speed UART-compatible serial ports and
one parallel port with EPP and ECP capabilities. Includes integrated keyboard
controller. Supports two of either 5.25- or 3.5-inch disk drives (1.44MB or

Introduction to ASUS TXP4 Series of Motherboards
Performance
• SDRAM Optimized Performance: The ASUS TXP4 series of motherboards
support the new generation memory—Synchronous Dynamic Random Access
Memory (SDRAM)—which increases the data transfer rate from 264MB/s max
using EDO memory to 528MB/s max.
• Double the IDE Transfer Speed: ASUS TXP4 series of motherboards with
Intel 430TX PCIset improves IDE transfer rate using Bus Master UltraDMA/33
IDE, which can handle data transfers up to 33MB/s. This new technology is
compatible with existing ATA-2 IDE specifications so there is no need to up-
grade current hard disk drives or cables.
•Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-
ter busses to memory to CPU.
• ACPIReady:ACPI(AdvancedConfiguration and Power Interface)is also imple-
mented on all ASUS 430TX series of motherboards. ACPI provides more En-
ergy Saving Features for future operating systems (OS) supporting OS Direct
Power Management (OSPM) functionality. With these features implemented in
the OS, PCs can be ready around-the-clock, yet satisfy all the energy saving
standards. To fully utilize the benefits ofACPI, anACPI-supported OS, such as
the successor to Windows 95, must be used.
• PC ’97 Compliant: Both the BIOS and hardware levels of ASUS TXP4 series
of motherboards meet PC ’97 compliancy. The new PC ’97 requirements for
systems and components are based on the following high-level goals: support
for Plug and Play compatibility and power management for configuring and
managing all system components, and 32-bit device drivers and installation pro-
cedures for both Windows 95 and Windows NT.
