2. FEATURES
2.1 The ASUS P2B-N Motherboard
The ASUS P2B-N is carefully designed for the demanding PC user who wants ad-
vanced features processed by the fastest CPU.
2.1.1 Specifications
• NLX: Features ASUS’ custom designed NLX form factor.
• Multi-Speed: Supports Intel Pentium® III (450MHz and faster), Pentium® II
(233MHz to 450MHz), and CeleronTM SEPP (266MHz and faster) processors.
• Multi-Cache: Supports processors with 512, 256, 128, or 0KB Pipelined Burst
Level 2 cache.
•
• Anti-Boot Virus BIOS: Features a programmable BIOS, offering enhanced
Advanced Configuration Power Interface (ACPI) support for Windows 98 com-
patibility, built-in firmware-based virus protection through Trend ChipAway Virus
codes, and autodetection of most devices for virtually automatic setup.
Intel AGPset: Features Intel’s 440BX AGPset with I/O subsystems and front-side bus
(FSB) platform, which boosts the traditional 66MHz external bus speed to 100MHz.
PC100 Memory Support: Equipped with two DIMM sockets to support Intel
PC100-compliant SDRAMs (8, 16, 32, 64, 128, or 256MB) up to 512MB. These
new SDRAMs are necessary to meet the critical enhanced 100MHz bus speed
requirement.
100/10Mbps LAN (optional): Features an onboard Intel 82558 Ethernet LAN
Controller (fully integrated 10BASE-T/100BASE-TX) and a LAN Activity LED
for monitoring network conditions.
•

SDRAM) or Rage IIC (4MB SDRAM) for 3D hardware acceleration.
PCI Audio (optional): Features onboard the ESS Solo-1 32-bit 3D positional
PCI audio which supports games and applications for Sound BlasterTM and Sound
Blaster Pro and full-duplex stereo.
•
• Thermal Sensor Connector with Optional Sensor: Accurately detects the CPU
temperature of processors with the ASUS Smart Fan or the Intel boxed proces-
sor heatsink with fan when connected to an ASUS P2T-Cable.
• Hardware Monitoring (optional): Provides an easier way to examine and man-
age system status information, such as CPU and system voltages, temperatures,
and fan status through the onboard hardware ASIC and the bundled LDCM by
Intel or PC Probe from ASUS.
• Riser Cards: Provides NLX power, IDE, floppy drive, LAN wake up connec-
tors; PCI/ISA slots; and USB and IrDA support.
• Ultra DMA/33 BM IDE: Comes with an onboard PCI Bus Master IDE controller
with two connectors that supports four IDE devices in two channels, supports Ultra
DMA/33, PIO Modes 3 and 4 and Bus Master IDE DMA Mode 2, and supports
