Ah ok - I understand now. Yeah, this is my first time ever building the linux kernel (or Xenomai) from source, so I was struggling a bit w/ what was Xenomai specific & what was linux kernel build-related... but after speaking w/ you guys here, it's all making sense now (:
I found some docs on installing a linux kernel & updating the boot loader, so I think I'm good now. Thanks so much for all the help with this!
