I won't say _no_ risk, but it's pretty safe. With a backup, I wouldn't worry about it at all.
I like using a pushpin best: http://www.coreboot.org/Developer_Manual/Tools#Chip_removal_tools A bios savior can be nice, too. >> Your northbridge and southbridge may also need some configuration >> before you can get serial debugging.

I looked in the source code but didnt find anything (might > have been looking in the wrong place though) Here are a couple of examples: no initialization: http://www.serialice.com/trac/serialice/browser/trunk/SerialICE/mainboard/qemu-x86.c?rev=105 some initialization: http://www.serialice.com/trac/serialice/browser/trunk/SerialICE/mainboard/amd_serengeti-cheetah.c?rev=105 a little more: http://www.serialice.com/trac/serialice/browser/trunk/SerialICE/mainboard/tyan_s2895.c?rev=105 Basically you take the minimal set of code that can initialize the serial port from Coreboot, and port it to SerialICE to support a new mainboard. The first two are simulators (qemu & simnow), so they're easy to play with. > > Btw, sorry for replying directly to you last time.
