Hmm, in fact there are no such messages ;)

If it was "Loading PilOS" first, and then "READ ERROR 09", it is "DMA
crossed 64K boundary" (http://www.bioscentral.com/misc/biosint13.htm).
This probably means that the BIOS is not able to load more than 64K
bytes.

I would recommend to wait a little more until the ARMv8 (arm64) port of
PicoLisp is ready. I'm currently testing on a Nexus 9 tablet. Arm64
seems to be the best architecture for pil64 so far.

Sparc CPUs are not supported, and will probably never be. There are
simply not many people wanting to use pil on a sparc, I suppose. And
porting to a new architecture is a huge task, the arm64 port took
several weeks of my spare time already.

Thank you! If anybody really wants to delve into it, I would be glad if
I could get information about the boot process on an ARMv8 machine (e.g.
the Nexus 9), to bootstrap PilOS on it.
