If everything fails I could send you an image of the 2.88mb disk.

This is a branch to an external target address.  Unfortunately this can
not be represented in ELF.

The switch of Linux/MIPS to ELF isn't complete yet.  You still need the
a.out compiler to compile the kernel; *all* user code is ELF.  Though
I promise this alredy for some time:  I'll fix the ELF problems with the
kernel as soon as I can and will then eleminate the a.out support in
