Board Layout

26 MIPS® Malta™ User’s Manual, Revision 01.07

The board has an ATX (305 mm x 244mm) form factor and is in accordance with the ATX speciﬁcation [12] with

regards to board size, mounting hole placement, connector placement, and height constraints.

The connector layout on the rear panel (namely, the shield design as described in Design Guide for Intel ATX Moth-

erboard I/O Implementations Version 1.1 [13] is a subset of Intel Core design #1. This enables the Malta Board to be

installed in an ordinary ATX chassis. Figure 4.2 shows the rear panel connector layout.

4.1 Connectors & Jumpers

All jumpers are standard 0.1” pitch. A dot by a pin indicates pin 1. On all jumpers, pins are numbered crosswise, that

is, the end pins are 1 & 2 (this is not always the case on other connectors).
