Notes for Digital Multias

• Multia VX51 (Intel models)
The Multia Service Information isn't very detailed what some of the jumpers of the Intel-based models mean. After playing around, I was able to find the meaning of jumpers W2, W4, and W5. These jumpers control the bus and processor speed (see tables below).

Bus Speed

W2	PCI
On	33 MHz
Off	25 MHz

CPU Clock Multiplier

W4	W5	Multiplier
On	On	3
Off	On	3.5
On	Off	4

CPU Speed

W2	W4	W5	Speed
Off	On	On	75 MHz
Off	Off	On	90 MHz
Off	On	Off	100 MHz
On	On	On	100 MHz
On	Off	On	120 MHz
On	On	Off	133 MHz
*	Off	Off	-
