Also, i tested it with: - Graphic Enabler Yes/No - PCIrootID 0/1/2 - Framebuffer Muskgrass

Further Info: I saw in Ati.c file that 6490m is associated with "RV740" Familiy. On wikipedia it says that it's a CAICOS from northern island. Probably you need only to switch that.

I'm not a coder...
I add this into ati.c and compile it from my branch...
following your provided info
the archive include the boot,boot0,boot0md,boot0hfs,boot1h
{ 0x6760, 0x1656103C, CHIP_FAMILY_CAICOS, "AMD Radeon HD
6490M", kNull }, // ErmaC no tested

How can i install it? Sorry for this question, never installed manually.
Comment 5 by František Nesveda, Sep 23, 2011
I just downloaded the source for r1562, changed the chip family in ati.c file, compiled, updated, and it works! Actually, the card still remains unrecognized, but now you can boot without NullCpuPM.kext, just with vanilla IntelCPUPM.kext. I'm testing different framebuffers now. @Fabio ErmaC How did you get to the number 0x1656103C? @Marco Masselli For example with Chameleon Wizard, you have to choose to install from folder on disk, choose the folder and select "update", then hit install.

I find the SubSys ID: 0x1656103C with a little an very quick search... And I found it here... (no Idea if is correct) http://us.battle.net/wow/en/forum/topic/2522465048 Pls if you find the correct setting... post here the result, and maybe the dev can add this to the main "ati.c" code. Thx Fabio

Still Card not supported. This mean that the ID is probably incorrect. How to find the card IDs? (there are at least 2 IDs of the 6490m, one for the GDDR5 version and one for the DDR3 version). How can i find it? i have a 6490m. where should i look?

Marco, František, post info about your card's like Daniel did above, but include the card's model too. Are these all 6490m? And please be patient; atm i don't know when i will be able to answer anyone :(

I've got an update on this topic. I ran a command in terminal: sudo lspci -nnvd 0x1002: | grep -B2 Subsystem It showed me that I don't actually have a AMD Radeon 6490M, but AMD Radeon 6470M. I believe this applies for Daniel and Marco too, as they both use the same laptop as me. (The difference between those two is that 6490M uses GDDR5 and 6470M uses DDR3) 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc NI Seymour [AMD Radeon HD 6470M] [1002:6760] (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Unknown device [103c:167d] 1656103C subsys ID is for 6490M, 167D103C subsys ID is for 6470M, both from the CAICOS family from Northern Islands. I use a custom Chameleon (in the trunk there are wrong families, so AICPUPM.kext panics when the discrete graphics is enabled) to boot with my 6470M enabled, but the card doesn't load, the ATI6000 kext (I don't know the exact name) doesn't get loaded. But I believe we're on a good way.
