II. FEATURES
Features
The ASUS P2B-D2 motherboard is carefully designed for the demanding PC user who wants
advanced features processed by the fastest CPU.
• Multi-Speed: Supports Dual Intel Pentium® II processors from 233MHz to 450MHz.
•
I2O: Includes Intel’s i960RD I/O processor with 32KB NVRAM, 4x512KB Flash
EEPROM, and 2 SIMM slots for up to 256MB of memory.
Intel Chipset: Features Intel’s 440BX AGPset with I/O subsystems and front-side bus
(FSB) platform, which boosts the traditional 66-MHz internal bus speed to 100MHz.
Enhanced ACPI and Anti-Boot Virus BIOS: Features a programmable BIOS, offering
enhanced ACPI for Windows 98 compatibility, built-in hardware-based virus protection through
Trend ChipAwayVirus, and autodetection of most devices for virtually automatic setup.
PC100 Memory Support: Equipped with four DIMM sockets to support Intel PC100-
compliant SDRAMs (8, 16, 32, 64, 128, or 256MB) up to 1GB. These new SDRAMs are
necessary to meet the enhanced 100MHz bus speed requirement.
• Onboard VGA: Features the S3 Trio64V2/DX VGA chipset onboard for faster 2D and
•
•
•
video acceleration.
• Wake-On-LAN: Supports Wake-On-LAN activity with the onboard network interface.
• Network Interface: Features the Intel 82558 Ethernet LAN Controller (fully integrated
10BASE-T/100BASE-TX).
•
•
•
• Alert-On-LAN: Supports Alert-On-LAN, which enables the host to send immediate alerts
to the network administors when there are hardware or operating system failures, or any
evidence of tampering.
• Adaptec SCSI Chipset: Features Adaptec AIC-7890 Ultra2 SCSI chipset that supports a
combination of 8-bit and 16-bit Ultra2, Ultra, and single-ended or standard SCSI devices
and the AIC-3860 transceiver chipset that bridges the compatibility gap between these
mixed environments without affecting system performance by taking advantage of the
benefits of low-voltage differential (LVD) technology.
SB-Link™: Features Creative’s SB-Link™, allowing SB16 compatibility, using Intel’s
PC-PCI and serialized IRQ protocols, to AWE64D or compatible PCI audio cards.
SMBus: Features the System Management Bus interface, which is used to physically
transport commands and information between SMBus devices.
PCI & ISA Expansion Slots: Provides one 16-bit ISA, three master 32-bit PCI, and three
secondary 32-bit PCI slots.
Intelligence: Supports Fan Status Monitoring and Alarm, Temperature Monitoring and
Alert, Voltage Monitoring and Alert, System Resources Alert, and Virus Write Protection
through the onboard Hardware Monitor, Intel LANDesk Client Manager (LDCM), and
ASUS PC Probe software, and Alert-On-LAN function.
Super Multi-I/O: Provides two high-speed UART compatible serial ports and one paral-
lel port with EPP and ECP capabilities. UART2 can also be directed from COM2 to the
Infrared Module for wireless connections.
• Desktop Management Interface (DMI): Supports DMI through BIOS, which allows
hardware to communicate within a standard protocol creating a higher level of compat-
ibility. (Requires DMI-enabled components.)
• Ultra DMA/33 Bus Master IDE/Floppy: Comes with an onboard PCI Bus Master IDE
controller with two connectors that supports four IDE devices in two channels, supports
UltraDMA/33, PIO Modes 3 and 4 and Bus Master IDE DMA Mode 2, and supports En-
hanced IDE devices. Two floppy drives of either 5.25inch or 3.5inch (1.44MB or 2.88MB)
are also supported without an external card. Supports Japanese standard “Floppy 3 mode”
(3.5-inch disk drive: 1.44MB, 1.2MB, 720KB) and LS-120 floppy disk drives (3.5-inch disk
drive: 120 MB). BIOS supports IDE CD-ROM or SCSI device boot-up.
IrDA: Supports an optional infrared port module for wireless interface.
•
• Concurrent PCI: Allows multiple PCI transfers from PCI master buses to memory to CPU.
