OverDrive® Processor Support
The Advanced/ML baseboard has a 321-pin Type 7 Zero Insertion Force (ZIF) socket that provides users with a performance upgrade path to Pentium(r) Overdrive Processors.

The table below lists the jumper settings required for the 320-pin PODP 3V-xxx OverDrive processor. These OverDrive processors select their clock ratios internally and do not use the baseboard's internal clock ratio jumpers. These OverDrive processors also work over a voltage range that includes both VR and OVD voltage ranges, so the user does not need to change the voltage specification jumpers on the baseboard.

Pentium				Original 	External	External CPU	
OverDrive			Processor	Processor	Clock Jumpers
Processor 			Type		Clock		(J7K1-C)

Intel PODP 3V - 125 MHz 	75 MHz		50 MHz		pins 2-3, 5-6
Intel PODP 3V - 150 MHz		90 MHz		60 MHz		pins 2-3, 4-5
Intel PODP 3V - 166 MHz		100 MHz		66 MHz		pins 1-2, 5-6

Real Time Clock Battery Replacement
The battery can be replaced with a Sanyo CR2032, or equivalent, coin cell lithium battery. This battery has a 220 mAh rating.
