fast multimedia graphics and video. Includes I/O subsystems.
• Enhanced ACPI & Anti-Boot Virus BIOS: Programmable BIOS (Flash EEPROM),
offering enhanced ACPI for Windows 98 compatibility, built-in hardware-based
virus protection, and autodetection of most devices for virtually automatic setup.
• Versatile Memory: Equipped with two DIMM sockets to support 8MB–128MB
168-pin 3.3Volt SDRAM/EDO memory modules up to 256MB.
• AGP Slot: Supports Accelerated Graphics Port cards for high performance, com-
•
ponent level interconnect targeted at 3D graphical display applications.
ISA & PCI Expansion: Provides two 16-bit ISA expansion slots and two 32-
bit PCI expansion slots.
• Wake on LAN: Supports Wake on LAN activity through optional ASUS
PCI-L101 Fast Ethernet card.
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)
• Ultra DMA/33 BM IDE: Comes with an onboard PCI Bus Master IDE control-
ler with two connectors that supports four IDE devices in two channels, sup-
