I have a somewhat old laptop (Mitac 4022) with an Intel 486 DX2-66
processor. Since the 486 DX4-100s are really cheap now (BTW, there is
something 486-compatible faster than a DX4-100 out there?), I tought
it would be a nice idea to do an CPU upgrade in my notebook, if it is
at all feasible. From what I could understand in the manual, it seems
to be quite possible to do such upgrade.
I've already seen the chip and it seems to be a "normal" Intel DX2-66.
There are switchers to select the CPU from the following types: SX,
DX, DX2, P23S, P4S, and P24S. As you see, there is no DX3 or DX4, but
I think it's no problem since the settings for DX and DX2 are
There are also switchers for the CPU-frequency, but just two choices
are available here: 25 and 33 MHz. This is ok, because the DX4-100
operates at 33 MHz, right?
There is also a jumper for selecting between a "S-series CPU" and a
The manual has nothing about the CPU voltage, but I hope it's already
cared of in the CPU-type settings.
What are my chances of succeeding in such upgrade, in your opinion?
Thank you in advance for your answer.
