Re: [XenPPC] Re: Howto build the xen blob and zImage with init rd

[Maria Butrico <butrico@xxxxxxxxxxxxx>]

Well it works only in the sense that make completes with no errors 
producing a rather large xen file :).  However, the file does not boot 
on hardware nor does it boot on the simulator (mambo).   I suspect a 
file format error
On the simulator:

There are a few gremlins here, such as where boot: k42 came from and how 
is exactly yaboot not getting in the way.  I should add that a plain 
xen, i. e., one without vmlinux, get further in the startup sequence 
than this one. It stops only when it cannot find a dom0 image, as it 
should.
