The VP-1020 card is an EEPROM less card, whereas the VP-1020A is the one 
that has an EEPROM, which has the Subsystem ID. The VP-1022 is an exact 
clone of the VP-1020A, except some difference in updated firmware ..

There is no difference in the contents what i told you previously, but 
since just to be comfortable, i am attaching the output with the tool 
you pointed to..
