Chipsets

Chipset	LCD support	CRT support
i810	yes	yes
i815	yes	yes
i830	yes	yes
i845	yes	yes
i852/i855	-	yes*
i865	-	-
i875	-	-
i915	not tested**	yes

* i855 users who have flickering problems may want to try the i855crt project to see if that works better.

** Please inform me if you can use this function successfully.

If your chipset is not supported, it's not entirely hopeless. To test these chipsets, a couple of code modifications are necessary:

• add a #define for the chipset's PCI ID (i810switch.c:64 or so)
• add a line for the chip in the i810_chip function (new chips should probably be of type I830) (i810switch.c:97 or so)
• recompile and try it out

If it works, please send Ken Mano an email. (mano at agate.plala.or.jp)

Note that this will only enable CRT support, as there isn't currently any LCD support for any of the i830-type chipsets.
