The old code use below comparion as condition to terminate valid range check without care whether there are more ranges in later BARs: " if (start == 0) break; " I guess original author think (or make a mistake) when we meet a address range begin from zero means it is a invalid address range, and no valid address ranges in remain BARs. So I said: We can't break the loop when meet range whose start address is zero, without check it and remaining BARs' range.
