Features of the ASUS P2L97A Motherboard
The ASUS P2L97A is carefully designed for the discriminating PC user who wants
many features processed by the fastest CPU. This motherboard:
•
•
• AGP Chipset: Provides ATI 3D RAGE Graphics Accelerator chipset, with on-
board video controller and 4MB of 64-bit SGRAM memory. Accelerated Graphics
Port (AGP) features high performance, component level interconnectivity tar-
geted at 3D graphical display applications.
Processor Support: Intel Pentium® II (233MHz–333MHz) processor.
Intel Chipset: Features Intel’s 440LX AGPset with I/O subsystems.
• AMC Connector: Supports ATI Multimedia Channel (AMC) for additional ca-
pabilities, such as optional TV tuner card available for video capture, video cap-
ture, videophone, TV overlay, or TV tuner applications.
• Easy Installation: Supports autodetection of hard drives, PS/2 mouse, and Plug
and Play devices to make setup of hard drives, expansion cards, and other de-
vices virtually automatic.
ISA & PCI Expansion Slots: Provides two 16-bit ISA and four 32-bit PCI slots.
Super Multi-I/O: Provides one high-speed UART compatible serial port and one
parallel port with EPP and ECP capabilities.
•
•
• 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)
• CPU Built-In Level 2 Cache: 512KB or 256KB Pipelined Burst Level 2 cache
in the Pentium II Single Edge Contact (SEC) cartridge.
•
• Versatile Memory Support: Equipped with three DIMM sockets to support (8,
16, 32, 64, or 128MB) 168-pin SDRAM/EDO memory modules up to 384MB.
PCI Bus Master IDE Controller: Comes with an onboard PCI Bus Master
IDE controller with two connectors that supports four IDE devices in two chan-
nels, supports 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.
Supports two drives of either 5.25-inch (360KB or 1.2MB) or 3.5-inch (720KB,
1.44MB, or 2.88MB) disk drives. Supports Japanese “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.
Performance: 528MB/s data transfer rate using SDRAM, 33MB/s IDE transfer
rate using Bus Master UltraDMA/33 IDE, concurrent PCI allows multiple PCI
transfers.
SCSI Bios: Supports optional ASUS SCSI controller cards through onboard
SYMBIOS firmware.
