Hi,
I had a quick look. I'll test the TV-out in a day or two.
case PCI_CHIP_RADEON_LZ:
info->IsMobility = TRUE;
info->ChipFamily = CHIP_FAMILY_RV100;
+ info->videoChip = VCHIP_RT1;
+ info->tvoutType = TVOUT_INTERNAL;
break;
You can get inspiration from the auto-detect routine in the tv_output
patch. http://megahurts.dk/rune/tv_output.html (its GPL...)
- /* R420 family not supported yet */
- if (info->ChipFamily == CHIP_FAMILY_R420) return;
thank you!! =)
