II. FEATURES
Features
The ASUS P2B-L/P2B-S/P2B-LS motherboards are carefully designed for the de-
manding PC user who wants many advanced features processed by the fastest CPU.
•
•
Multi-Speed: Supports Intel Pentium® II processors from 233MHz to 450MHz.
IntelAGPset: Features Intel’s 440BXAGPset 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
(Flash EEPROM), offering enhancedACPI for Windows 98 compatibility, built-
in hardware-based virus protection, and autodetection of most devices for virtu-
ally 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 1024MB.
Network Interface: Features the Intel 82558 Ethernet LAN Controller (fully
integrated 10BASE-T/100BASE-TX) as an option and a LAN Activity LED
connector (optional/reserved) for monitoring network conditions.
•
Adaptec SCSI Chipset: Features Adaptec AIC-7890 Ultra2 SCSI chipset (op-
tional) that supports a combination of 8-bit and 16-bit Ultra2, Ultra, and single-
ended or standard SCSI devices and AIC-3860 transceiver chipset (optional)
that bridges the compatibility gap between these mixed environments without
affecting system performance by taking advantage of the benefits of low-volt-
age differential (LVD) technology.
•
AGPSlot: SupportsAccelerated Graphics Port cards for high performance, com-
ponent level interconnect targeted at 3D graphical display applications.
PCI/ISA Expansion Slots: Provides four 32-bit PCI and two 16-bit ISA slots.
Intelligence: Supports Keyboard Power Up, Fan Status Monitoring and Alarm,
Temperature Monitoring and Alert, Voltage Monitoring and Alert, System Re-
sources Alert, and Virus Write Protection through the onboard Hardware Moni-
tor, Intel LANDesk Client Manager (LDCM), and ASUS PC Probe software.
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.
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 Enhanced 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: 1.2MB)
and LS-120 floppy disk drives (3.5-inch disk drive: 120 MB, 1.44MB, 720KB).
BIOS supports IDE CD-ROM or SCSI device boot-up.
