So I'm just going to update this post with the threads findings to make life easier for anyone that may end up with one of these systems.
The Motherboard is an Aries_3P, a FIC produced board for AIWA, for the PC-MT601, the P54C CPU socket is single power and the clock generator can handle only 50hz, 60hz and 66hz, the dip settings are as below:
There is one undocumented clock rate configuration, 1/2 1/2 for JK1 and JK2, according to the datasheet for the clockgen, this is just a test mode.
Without modification or a interposer the highest clock speed is 200mhz, a Pentium non-mmx 200 will work.
Original post follows -----------------
So, I have a strange board for which I cannot find the manual.
It's an Aries _3P, DOC: 14760, which has a Socket7 slot marked with P54C.
It has the following tables for the jumpers relating to CPU:
JK1 - JK2 - 202CLK
2/3 - 2/2 - 50MHz
2/3 - 1/2 - 60MHz
1/2 - 2/3 - 66MHz
FRACTION(JCP?) - JC1 - JC2
2/3 - 2/3 - 2/3
1/2 - 1/2 - 2/3
1/3 - 2/3 - 1/2
2/5? - 1/2 - 1/2
This is on a VIA chipset, with a VT82C576M
It currently has a P54C Pentium 150 installed, so I'm wondering what options I have for CPU upgrades, and how to handle the Fraction table (clock rates pretty self explained), would the fastest I can install be a P54C P200?
Here's an image of the actual board:
