-> Im fairly new at bootp() installs and Im getting the following error...
-> Cannot load bootp():/tftpboot/netbsd.ram
-> Illegal f_magic number 0x7f45, expected MIPSELMAGIC or MIPSEBMAGIC.
-> Unable to load bootp():/tftpboot/netbsd.ram: execute format error
-> Any body able to help on this...
-> oh this is a challange M (simmilar to the s)

This means that your Challenge M (which is actually basically an Indigo2
the same way the S is basically an Indy) has an old PROM and doesn't 
understand ELF kernels.  While my Challenge S (and maybe Indy too, though
I don't recall) boots ELF kernels just fine, my Indigo2 needs an ECOFF
kernel.

Chalk it up to PROM limitations,
