OVERVIEW
The name Mitsubishi Electric is known the world over for
quality, reliability and dependability. The Trimond™ HN440
“Hornet” ATX motherboard from Mitsubishi Electric
Motherboard Division continues this tradition, combining
innovative design with high-quality components.
The HN440 is an ATX profile motherboard designed around
the use of Intel Celeron™, Pentium
®

®
III
processors. All three package variations are supported – SEPP
(Celeron™), SECC (Pentium
®

®
II
and Pentium
®

The motherboard is intended for use with a logic-controlled
“soft-switch” Power Supply Unit (PSU). Such a PSU is
needed for certain features of the motherboard, such as Wake-
on-LAN and power-saving Suspend and Standby modes.
The HN440 has the following major build options:
Intel 440ZX or 440BX chipset
Audio system with joystick/MIDI support (440BX only)
Heceta II System Monitor
Note
The number of memory (DIMM) sockets is affected by these
build choices. Builds with 440ZX have two DIMM sockets;
builds with 440BX have three DIMM sockets.
