the 9atom cd boots to 32-bits, but the 64-bit kernels are right there. it should be no problem if you have a 64-bit capable machine to boot into a 64-bit kernel after compiling /sys/src. the reason i don't boot directly to 64-bits is because that's probablly a lot of busy work without a lot of benefit. also all 64-bit intel run 32-bit kernels, but not vice-versa. > I did boot nix with the new boot loaders from a CD image, so that part > worked.

(that is, paging is off.) it has the ability to boot 64-bit, pae or po32b. (plain old 32-bit.) the main requirement to boot 64-bit it to accept S_MAGIC. (i am still using ye olde 9load-e820 on the cd. this is laziness. it can also boot a 64-bit kernel, though. but it does not have boot menus.) > After booting the kernel, as Erik says, it should not be too hard. > > For ARM Richard Miller is doing an excellent work with his prerrolled > Plan 9 images for the raspberry pi, so that is probably the way to go. 9atom2 includes rpi. install on a 32- or 64-bit intel, and cd /sys/src; objtype=arm mk install - erik
