The 'card' Resource
The 'card' resource contains a Pascal string (that is, a length byte followed by
an ASCII string) identical to the name of a video card. (The name of a video card
is located in the Board sResource data structure in the ROM of the card, as
described in Designing Cards and Drivers for the Macintosh Family, second
edition.) The extension file can contain as many 'card' resources as you wish,
so that one extension file can handle several versions of one video card. The
Options dialog box displays the name in the 'card' resource unless you also
include an 'STR#' resource in the extension file, as described in
function. For a description of video cards, see Designing Cards and Drivers for
the Macintosh Family, second edition.
