This is a little out of date, but I found this looking for some other info. This is not true, there is Firmware on the PCI-GPIB card. In fact, I had to move all the cards into a PeeCee and run a Firmware update program to update the cards to handle a dual processor Mac. If the cards "do not have firmware" then what was I updating with the firmware update?
I think there is "firmware" on all PCI cards that have basic identification and timing info.
