Chromebook and LinuxCNC

Will become HP Laptop -> Linux OS -> LinuxCNC -> Mesa 7i76e -> JKL-4030 Drivers.
It is possible to plug a Parallel port BOB into the 7i76e but you loose all of the benefits of the vastly superior Mesa hardware.You would be far better off rewiring to the Mesa step gens and I/O ports.
I think you are still missing something. You CANNOT use a Warp9 ESS smoothstepper with LinuxCNC. Its a piece of hardware built to address the inadequacies of Mach3/4 and Windows and IS NOT SUPPORTED under LinuxCNC. The reason why its not supported is that its not required as LinuxCNC does not have the weaknesses that it was designed to fix in Mach.
As Andy said, the Mesa 7i76e is vastly superior and only a few $ more.

An alternative is just to view the PC motherboard as one more component, and mount it in the electrical panel.
That is a Mini-ITX motherboard (one that takes a single 12V input) with a Mesa 5i24 mounted on an "over the top" PCI riser and a stack of 7i84, 7i44 and 7i49 cards. For storage there is an 8GB SATA DOM module (£20) plugged directly into an SATA port.
8GB seems plenty for the OS and a sane number of G-code files.
I haven't tried Ubuntu 10.04 and linuxcnc.org/install-scripts/lucid/linuxcnc-install.sh yet and unaware if it's version of LinuxCNC is separate boot up.

I don't really understand the question.
LinuxCNC is an application that run on a standard OS.
However, to work with LinuxCNC that OS needs to run on a special kernel, either PREEMPT-RT or RTAI.
So, LinuxCNC is two layers with the OS in the middle. You can install separately but it's easier to just install everything at the same time.
I suppose required is Ubuntu OS if to load Debain LinuxCNC both separate boots.
RTAI might not interfere with loading Debain LinuxCNC yet because it loaded with Chromebook and only USB ports but trying to open LinuxCNC did error probably due to RTAI incompatibility.
