Hey. I'm sorry for the off topic post, but I couldn't think of another
forum to ask my question. I'm just looking for information as to whether
there are different sizes Pentium processor dependent upon whether the
processor is for a desktop or laptop. I want to see if I can give my old
Hewlett Packard OmniBook a little more juice.
I don't recall there being any different processors in the first
Pentium. The big effort in power reduction was by a group who did a
power reduction project with the Pentium 3. Many of the laptops had
full sized Pentiums with novel cooling to make them work in a portable
laptop form factor.
There were a series of projects where Intel did processors to upgrade
previous families of chips with the newer technology. For example a 486
chip engineered to be happy with a 386 pin bus, but running at a higher
clock, and similar upgrades for 486 systems. These were called
"Overdrive" and were not power reduced as a goal of the product.
The Pentium was a big enough step that I don't know of any such for the
486, where a Pentium could be stuffed in. The BIOS became enough of a
factor in making the Pentium go that it was necessary. Such dropins they
had were all self contained that I mention in the previous paragraph.
The next act for Pentium (and quoting from this article) was MMX added
in. Pentium II of course went to the infamous Slot 1 / 2 form factor.

If you look up the processor you have in your Omnibook, some of the
Pentium P5's could be upgraded, but you had to be careful as some had
issues of being interchanged.
Thanks
