Hi,
I've made some progress to get modern kernels booting on the Jensen, but
not in a positive way. I got aboot compiled with a gcc cross compiler
after a lot of hackery, installed it on a second disk, attached that to
my Jensen and booted it:
>>> boot dka300 -fl i

I suppose something went awfully wrong during the cross compile of aboot,
but I simply fail to understand why it tries to unzip a gzipped kernel.
I tried an uncompressed kernel as well, that one failed with:
"ext2_bread: read error"
as well. As ext2_bread of aboot uses the SRM console API in the end,
I assume this is prone to break when cross compiling...
Has anyone tried to cross compile aboot before and got it working?
There certainly is no support for cross compiling built in, maybe for
a reason.
Anyway, I have not given up, but now I have to go for a full native build,
which means I have to build a newer gcc, as all my existing Alpha installs
are too old to carry a usable gcc for modern kernel builds and all my attempts
on a fresh install have failed. My fastest machine is a PWS 600au, so this
will take a while.
I hope I'm not too annoying,
CU,
Uli
