Hi,
I tried to boot gnumach (the microkernel used by the GNU/Hurd OS)
on plex86. It is a multiboot compliant kernel. I don't know what
the stack= argument means, so I copied the value that was used for all
other lines. The conf file I used and the output generated are attached.
It doesn't work yet, but maybe you can see something from the
output error. If you want a copy of the kernel to play with, let
me know and I will put it online (including source code).
GNUMach needs a module to hand control over to (as the Hurd
is a multiserver OS). Is module loading implemented?
Can't load-kernel find out which address to load a multiboot compliant
kernel to? I am sorry if this is a stupuid question, I am not that
familiar with the multiboot standard (I should probably read this up).
What is the correct conf file to attempt to boot a linux kernel?
I would like to try it out (for comparison).
BTW, I used the version from CVS today.
Thanks,
Marcus
