35 .Nd "accelerated color frame buffer"
41 family of chips are color frame buffers with graphics acceleration.
44 driver interfaces those frame buffers with the
49 chips are very common as low-end graphics chips in
54 They are found on-board in
62 OEM mainboards like the
64 They are also used on add-on cards like the
71 driver requires the chip which it is supposed to drive to be also
74 either by a built-in FCode driver package of the on-board firmware
75 or by additional FCode on the add-on card.
78 systems with an on-board
80 also have a built-in FCode driver package for this chip.
81 There are also mainboards like the
86 which have built-in FCode for certain
88 chips although they are not equipped with an on-board one.
89 Mainboards with built-in FCode for certain
91 chips can be used with any add-on card which is based on one of those
93 including cards which are equipped with x86 firmware and intended for
95 Otherwise an add-on card which comes with its own FCode like the
103 driver provides support for the following chips:

119 .Tn ATI 3D Rage Pro Turbo
129 .Tn ATI Rage L Mobility
131 .Tn ATI Rage Mobility
133 .Tn ATI Rage Mobility M1
