why my option rom can not execute by rombios???

[77]

Hi
my netcard's option rom seem wrong !!! it's length should be 8*512
but it will "call 2d78" (opcode e8 72 2b)---- jump out of range of option rom.
so rombios will execute some invalid instructions.
who can give me a hand , telling me whether my option rom is wrong?

Maybe your bootrom is actually larger than reported, like this:
