Acer Aspire desktop 5150LR built 97-3-10

Just got it (nostalgia; old games; etc). The BIOS gives no information about the system board and CPU. During bootup, this time a text screen shows "Pentium 133," and next time it shows "Pentium 166." This is disconcerting. Looking at the system board I find "V55LA MB." It has two open sockets for vram (514260ASL), and judging by its performance so far, I need to fill those sockets. It is running on all of 1MB video ram, and 16MB system RAM (72-pin EDO SIMM 60ns). I'd really like to know which CPU is that Socket 7 ZIF, and the bus speed of this board, because the system sorely needs a boost in performance/CPU upgrade. I intend to max out the RAM to 128MB. Why would the system show Pentium 133 this time and Pentium 166 the next time? Thanks!!

Turns out it was Pentium 150MHz. Can anyone help me with two more things: CPU frequency ratio for Pentium 200/MMX that I am installing; and where the CPU jumper settings are made. V55LA motherboard chart shows "off-on-off-on" for the Pentium 200, but I can't spot the "CPU jumper" on the motherboard. CPU frequncy ratio offers 5/2, 3/2, 2/1, and 3/1. I think I'm dealing with 66MHz FSB.
