HN440 USER’S GUIDE

Peripheral ports: Two serial ports. One parallel port with bi-
directional, EPP 1.9 and ECP (IEE1284) capability. Dual
Universal Serial Bus (USB) ports. PS/2-style mouse and
keyboard ports.
UltraDMA/33 IDE: The PIIX4e incorporates a dual IDE
Controller. Two motherboard connectors allow two devices
on each of two channels. Supports UltraDMA/33, Polled IO
Modes 3 and 4, and Bus Master IDE DMA Mode 2. Supports
Enhanced IDE and ATAPI devices.
Advanced Configuration & Power Interface: The PIIX4e
supports ACPI. Compatible with Microsoft/Intel PC97 and
PC98 Plug and Play standards. Support for a logic-controlled
“soft-switch” Power Supply Unit (PSU). Supports power-
saving Suspend and Standby modes.
PCI & ISA Expansion Slots: One ISA slot, one shared
ISA/PCI slot and three PCI slots.
AGP 2X Slot: Supports either Accelerated Graphics Port 1X
(66 MHz) or 2X (133 MHz) modes. (There is no on-board
video controller.)
Wake-on-LAN: Motherboard connector for input from
network cards that support Wake-on-LAN technology.
System Management: Desktop Management Interface
(DMI) support in BIOS. Heceta II System Monitor (build
option) supports monitoring of fans, power rails (+12 V,
+5 V, +3.3 V, CPU Core, -12 V and 2.5 V), motherboard
surface temperature, and chassis intrusion.
Battery back-up: On-board lithium coin cell with 5 years
typical life.
Concurrent busses: The major busses (processor, memory,
PCI and AGP) all operate independently to achieve a high
degree of concurrency. Most CPU-DRAM and AGP-DRAM
transfers can occur concurrently with PCI transfers and so
consume no PCI bus bandwidth.
