I'm interested in throwing Chrome OS on an old Powerbook just for the hell-of-it.

Does anyone know if it's possible to install it as the only OS? I'd rather not have to run a VM for this.

How old is your powerbook? Does it have x86 architecture? – lemonginger Sep 13 '11 at 17:23
@lemonginger PowerBooks are always PowerPC; MacBooks are always x86. The only Mac models that kept their name through the Intel transition are the iMac and Mac mini. – CajunLuke Sep 13 '11 at 17:54
egg on my face. can never keep up with what names refer to which versions. In that case, I think Chrome OS will not run on PPC, but someone with a more expert opinion could prob answer definitively – lemonginger Sep 13 '11 at 17:59

Based on reading this page, it appears to be technically possible to build Chrome OS for PowerPC. (They do mention that V8 won't work, but that implies that most everything else does.) Getting it to be the primary OS and boot, however, is the tricky part. I suggest partitioning the hard drive to dual-boot between OS X and Chrome OS (at least initially) so you have a known-good system. You may also have trouble with the drivers.
