Processor speed selection

These settings need to be changed after a Pentium processor upgrade. They must not be changed otherwise.

	FS1	FS0	BF	BF1	ISA
Pentium 75 MHz	1-2	3-4
Pentium 90 MHz		3-4			9-10
Pentium 100 MHz	1-2				9-10
Pentium 120 MHz		3-4	5-6		9-10

Disabling the on-board video controller

You may need to disable the motherboard EVGA video controller and video BIOS if you add a video adapter expansion card (check the documentation that came with the card to make sure). You do this by removing the jumper from PL22, the VESA options jumper block.

On-board EVGA	PL22
Enabled (default)	1-2
Disabled	Open
