I’ve been staring at a pentium m 778 on ebay for months. Only thing is, its bga. But, with some voltmods, I think I could really get it to crank some clock. With clockgen, I could probably get 2.8-3ghz. Much better than 2.13. All in one laptop.
No. Because pins are not created equal. What may be a RAM address line on a particular pin for that BGA package, might have a totally different function on another socket. I suggest to get a data-sheet of both the BGA and a regular socketed version of the Pentium chip and compare pin-by-pin if their functions are equal. If just 1 pin differs, you’re screwed if you try anyway
As stated above, directly no, but I have seen multiple Mobile intel CPUS that are BGA soldered onto a PCB that translates the pins to LGA so you can put mobile CPUs in desktop motherboards. *These also need bios mods to work.
So maybe something like that exists, but its a big gap in years to find something that niche and old now.
