Features of the ASUS P2B Motherboard
The ASUS P2B is carefully designed for the demanding PC user who wants ad-
vanced features processed by the fastest CPU. This motherboard:
• Versatile Processor Support: Intel Pentium
®
II (233MHz–400MHz) processor.
• Intel AGPset: Features Intel’s 440BX AGPset with I/O subsystems and featuring
Intel’s “front-side bus (FSB) platform”, which boasts a 100-MHz internal bus speed.
• Programmable Flash ROM: 2Mbit programmable bios (Flash EEPROM), offer-
ing built-in, hardware-based virus protection and enhanced ACPI for Windows 98
compatibility, autodetection of hard drives, PS/2 mouse, and Plug and Play devices
for virtually automatic setup of hard drives, expansion cards, and other devices.
• AGP Slot: Supports Accelerated Graphics Port cards for high performance, com-
ponent level interconnect targeted at 3D graphical display applications.
• ISA & PCI Expansion Slots: Provides three 16-bit ISA and four 32-bit PCI slots.
• 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.
• Desktop Management Interface (DMI): Supports DMI through BIOS, which
allows hardware to communicate within a standard protocol creating a higher
level of compatibility. (Requires DMI-enabled components.) (See section V)
• PCI Bus Master IDE Controller: 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, such as Tape Backup and CD-ROM drives.
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, 720K). BIOS supports IDE CD-ROM or SCSI device boot-up.
• CPU Built-In Level 2 Cache: 512KB or less Pipelined Burst Level 2 cache in
the Pentium II Single Edge Contact (SEC) cartridge.
• Versatile Memory Support: Is equipped with three DIMM sockets to support
(8, 16, 32, 64, or 128MB) 168-pin SDRAM/EDO memory modules up to 384MB.
• SCSI BIOS: Supports optional ASUS SCSI controller cards through onboard
SYMBIOS firmware.
• IrDA: Supports an optional infrared port module for wireless interface.
• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-
ter busses to memory to CPU.
• Intelligence: Supports Fan Status Monitoring and Alarm, Temperature Moni-
toring 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.
