Hi, patrick, here's what I did, step by step, to get it to work: ( I'll make it very detailed for the benefit of others)
1. boot into windows
2. download softMMc from:http://www.entechtai...es/softmccs.exe
3. install the software, run it and choose from the file menu, 'save report' - save it to your desktop and close the program.
4. Open the saved report, somewhere towards the bottom you will see
Raw EDID =
select and copy the long continuous string (mixture of numbers and letters) you see after this.
5. To change hex to base64, go to the website:http://home2.paulsch...et/tools/xlate/
and paste the raw edid data into the HEX box and click the'decode' tab under that box
6. copy what appears in the base64 box and paste into a text file and save for safe keeping.
7. If you can't/don't access your NTFS partitions from OS X, copy this file to a USB stick, HD, FAT32 partition etc.
8. boot back into OS X
9. download RadeonHD kext from the first post in this thread
10. right-click the kext, choose 'show package contents', open the folder 'contents'
11. open the file with your saved edid in b64 format and copy the string
12. Going back to the RadeonHD.kext contents folder, open the file info (info.plist) with Textedit and scroll down until you come to the section EDID and highlight the 3 or 4 lines of text (this is an edid from another PC) - then paste your own edid instead. Don't worry if this appears as one long line or 2 lines or whatever, just make sure it starts at the right place.
13. close/save the modified plist, close the kext
14. download osx86 tools from:http://code.google.com/p/osx86tools/
15. run osx86 tools, choose install kexts, choose RadeonHD kext , follow the prompts
Some further notes about my experience:
I first tried the kext without putting my edid into it (it already contains an edid from some other PC) - it worked fine but the only resolutions available were 640x480, 800x600, 1024x768, 1280x1024, 1400x1050 - which were of no use to me. With my edid inserted I only get 1280x800 - but that's all I need.
After rebooting the first time, it seemed to hang at a white/grey screen, I forcibly powered off, rebooted and it's been fine since.
Instead of a cursor I initially got a opaque box with a thin green line (quite fun to use!), so I redited the plist, changing
and rebooted a couple of times
Thanks again to Dong for his work.
