Vladimir,

Thanks for the information about different chip classes. I added some
entries on TV-in,TV-out, dual-head, 3D capabilities and programming
intaerfaces: However, very few entries are filled in so far. Something
of interest missing in the table?

Updated table below:
 Card name             Chip class     3D     TV-in     TV-out    Dual head     Prog.I/F    I2C-bus
 ATI 3D Rage LT Pro    ragepro        Yes    No        Yes       ?             ?            ?
 Rage128               rage128        ?      ?         ?         ?             ?            ?
 Rage128pro            rage128pro     ?      ?         ?         ?             ?            ?
 radeon mobility M6    rv200          Yes?   No        Yes,RT?   ?             ?            ?
 radeon 7500           rv200          Yes?   ?         Yes,RT?   ?             ?            ?
 radeon 8500           r200           Yes?   ?         ?         ?             ?            ?

RT=Rage Theatre

Where do the AIW chips come in and what is a plain radeon?

Thanks,
Svante
