Hmmm....Well, you can damned try and see if it works. Although heat
build-up in the 770Z chassis is gonna be a problem.

Hmmm...I'm not sure. The A20M is supposed to be a Speedstep okay
version...so there should be a BIOS flash utility option to do that.

Well, I do know that phlash, the Phoenix BIOS utility, have functions that
allow you to define your own platform.bin and bios.rom files to flash the
BIOS with. Technically, you can use the /ro=file option to "suck" the
settings off a 700Mhz machine and then /b=file option to force-flash it
back into a 550Mhz machine, but this is a theoretical suggestion. YMMV
and this advice is to be taken as-is.
