1. why we need to patch aticontoller?<br>
2. why some gets display without patching ?<br>
3. why some use edid of the displays ?<br>
4. what are sense ids?<br>
<br>
answers<br>
1. we need to patch the aricontroller because the default mac books has the following configuration having default sense ids <br>
and the ati configuration which we writes is hidden in bios loader of
the macbooks , we can use any of the configuration (according to our
display ports as we have 4 then must use any configuration having four
sense ids and then patch accordingly ) so we patch it so that the kext
fully recognize our displays and give good and compatible output.<br>
<br>
2. some are luckly as the defaults sense ids of the aticontroller matchs with there laptop display configurations.<br>
<br>
3. we use edid of displays when we did not patch our sense ids then the
aticontoller does not fuly recognize the displays and gives the standard
output which is not mostly compatible with the lvds thus display does
not comes hence we use use edid to make the ati controller forcely
recognize the display and give us the output hence with the use of the
sense id we does not need edid or vice versa.<br>
<br>
4. sense ids are like the address of the displays port from where kexts
use to get the data and the supported resolution of the displays.<br>
