Found two VBioses from T440p's image but only the last one is saved. #27

The T440p's bios image https://download.lenovo.com/pccbbs/mobiles/gluj42us.iso contains two intel 8086:0406 vbioses. I checked it with UEFITool and it appears they are different in version one is 2171 and another is 2179. But using this VBiosFinder, the output folder only has the second one which is the 2179 one.

Here is the output.

Looks to be another case of https://github.com/coderobe/VBiosFinder/issues/20 - thanks for reporting. I'll probably end up rewriting this entire thing at some point, it's a bit of a mess.

Should be fixed now
