agreed - it seems updating firmware via windows is typically much
easier. In this case however, I can't seem to locate windows drivers
that support the MC7750. The 'one-touch' windows firmware update
utility fails to identify the card which is no surprise as the device
nodes in windows device manager all have exclamation points next to
them. Anyone know where to download Windows7 drivers for MC7750 so
that I can get this firmware updated?
