Sorry, Jeff, but these days (the last 20 years or so) cards have some
bootup code in the firmware. PCI cards in particular run a variant of
Forth known as Open Firmware that's initialized and run from the
motherboard. It's supposed to be manufacturer-neutral, but not
required to be so. Some cards are supported on macs, some are
supported with firmware upgrades, some manufacturers have trouble
spelling macintosh.

Point taken about the soldering <g>.
