Passing a VBIOS rom to the card used for passthrough is required for some cards, but not all.
Some cards also requires you to patch your VBIOS romfile, check online if this is neccessary for your card.
The VBIOS will be read from $VBIOS_PATH
This process will require the use of sudo and will run the following commands:

cat $VBIOS_PATH > $SCRIPTDIR/$QUICKEMU/vfio_card.rom
