as no symbol. Now they will be relative to the last symbol. - when anything was looked up in a segment with a nonzero base address, it would print "non-zero base" and abort the lookup. I disabled this behavior so that it would look up the symbol based on the EIP despite the base. This change makes it possible to trace user processes, in which the base is 0xc0000000. - symbol lookup also used to fail in 16-bit code. Since the address translations rules for 16-bit code are simple enough, I just compute the 20-bit linear address and look up the symbol with it. Now I can load a symbol table of the ROMBIOS and it works.
