Well it looks like the x86 via Esther processor is not compatible with the default 686 build image that Gutsy is shipping with. This is possibly not correct but this bug in Edgy leads me down that path:
Although the version is different and the processor is different I'm nervous about it. I may have to go with the "alternate install cd" and start out with the xubuntu, then do the "install mythbuntu from an exisitng install"
Maybe this is something else I'm running into or an error on the CD I pulled from (I downloaded both the 64 and 32 bit versions). The only think that makes me wonder is that I booted my laptop off of it just fine. Booting up this new system gives me an error: Your CPU does not support long mode. Use a 32bit distribution. Which makes me wonder if my work laptop actually has a 64 bit chip in it!
