It's probably a flashed PC card - and perhaps flashed with the wrong
bios if the full memory is not showing in profiler. If the original manuf
sticker is intact the card can be identified with the 102 number from it at

fixing a bios mismatch can be problematic so I should return it as
faulty.....

Resoldering these jumpers is purely in order to remove the 64k bios
flash lock to enable a 128k bios flash for macs as the PC bios is 64k or
less.
