MITSUBISHI ELECTRIC MOTHERBOARD DIVISION PAGE 21 OF 45
This is EPP 1.9 and IEE1284 (ECP) compliant and is compatible with a standard (output only)
PC parallel port as well as a bi-directional (PS/2 style) parallel port. There is a 25-way D-type
connector on the rear panel.
Two UltraDMA33/ (66 - ICH1) IDE ports are provided with the controller integrated into the
ICH. This allows for a maximum of four drives to be connected - two to each port. Normally the
primary port would be used for hard disk drives and the secondary port for CD-ROM or DVD
drives. 120MB floppy drives have IDE interfaces.
Both IDE controllers are independent and both can bus-master data into memory for improved
performance. The interfaces are also, of course, compatible with standard ATA drives.
The motherboard has two USB ports at the rear with the controller integrated into the ICH.
There is chassis intrusion detection available on motherboards with the 87366 fitted. This is
capable of detecting an intrusion even when AC is disconnected (the logic is powered from the
3V lithium cell).
A voltage regulator conforming to the Intel VRM8.2 standard supplies power for the processor
core. The motherboard automatically selects the correct processor voltage.
An IEC-type CR2032 3V lithium coin cell and holder are fitted to the board. Note that when the
motherboard is powered off but the AC remains connected (the standby rail is active) the battery
is not used.
