This is normal if you don't have the start symbol defined.  1ST_READ.BIN (or
whatever binary that is specified in IP.BIN) is always loaded at 0x8c010000.
As long as netbsd's entry point is the first bit of code in the .text segme=
nt,
you don't need start (or if it isn't just define start to branch to the real
netbsd startup code).  Next time ignore the warning and you should be fine.

That's because the Dreamcast is attempting to execute "shiggity shiggity
shwa" as valid SH-4 machine code.  Obviously that won't work :).
