ss_insaneguy Posted November 5, 2009 Share Posted November 5, 2009 Hello everyone, I stumbled across the following forum post yesterday (http://www.insanelymac.com/forum/index.php?showtopic=192792) and, while it was for the x1350, I attempted the same steps applied to the x1400...and it worked! So this is what I did. I've tested this with 10.5.7 iAtkos and iDeneb versions. My laptop is an Acer 5672. 1. Download the ATI_Kexts.zip file from here or the aforementioned forum post and extract it. 2. Using any text editor, edit the info.plist file from ATIRadeonX1000.kext and change the following string: from 0x71961002 to 0x71451002 (because the dev id for the Mobility x1400 is 7145. It's 7196 for the x1350. 3. Download a freeware program called softMCCS. This is used to extract your EDID information for placement inside the RadeonHD.kext info.plist. 4. Once downloaded, launch softMCCS and go to file->save EDID as->choose file type "viewsonic EDID file"->save your edid.dat. 5. Open this edid.dat file with any text editor, and remove all the white space from the beginning of the file, and remove the headers and columns (so essentially, you're left with rows and columns of xx data). Now format all of these xx data bits into groups of 8 followed by a space, so you basically have 32 chunks of xxxxxxxx data (xxxxxxxx xxxxxxxx etc...). See the attached files for my modified versions. Heck, these files might even work for you. 6. Now that we've got our modified .dat file, copy and paste all of the 32 chunks, and paste them into the RadeonHD.kext info.plist file, under the section <key>EDID</key><data> 7. Install either flavour of OSX (might work with other versions but I haven't tested this yet). Using the free program KextHelper, first install your modified ATIRadeonX1000.kext, repair disk permissions using Disk Utility, and reboot. 8. Again using KextHelper, then install your modified RadeonHD.kext, repair disk permissions, and reboot. If you get a kernel panic, reboot using -v -f commands. 9. If all boots well, you should now be able to change your screen resolution to 1280 x 800 with QE/CI. The only problem I have now is mouse tearing. But I'm sure that's an easy fix. I just haven't looked into it. Let me know how it goes for you! UPDATE: I've created a PDF guide with images for the above steps. Let me know what you think!

ss_insaneguy Posted November 9, 2009 Author Share Posted November 9, 2009 Sure, I'll take some screenshots for you. I'll start from the beginning and try to document my steps via screen grabs. I'll try to get them within the next 24 hours. Link to comment Share on other sites More sharing options...
ahmettt Posted November 10, 2009 Share Posted November 10, 2009 Thank you so much. I have Ati HD 2300 and works now with this method. I'm using now with 1280x800. Only small traces of mouse issue, available. Thank you again!!! Link to comment Share on other sites More sharing options...
penguin@ries Posted November 10, 2009 Share Posted November 10, 2009 Thanks you very much!!!!!! I have succeeded in making max resolution on Dell Inspiron 6400/E1505, Graphic is ATI Radeon X1400. Formerly, the resolution is only 1024x768, after doing as your instruction, the resolution has changed into 1280x800. Thank you!!!! About mouse issue, if you don't edit the info.plist file from ATIRadeonX1000.kext and change into the string 0x71451002, the mouse lag won't appear, but QE/CI won't be supported.

ss_insaneguy Posted November 10, 2009 Author Share Posted November 10, 2009 Alright, so I've created a PDF guide with images for the steps above. Check out the first post for the update. Let me know what you think! Thanks. Link to comment Share on other sites More sharing options...
voxelized Posted November 14, 2009 Share Posted November 14, 2009 Thanks! Now I get 1280x800 on an old laptop that rarely used before! I already had a working ATIRadeonX1000.kext (hardware acceleration + QE/CI) so I'd recommend people to only install RadeonHD.kext w/ EDID. Link to comment Share on other sites More sharing options...
ss_insaneguy Posted November 15, 2009 Author Share Posted November 15, 2009 Awesome voxelized, penguin@ries, and ahmettt! I'm so glad that it's working out for you three. Spread the word! I know there were a ton of posts with x1400 issues. Hopefully this will solve some problems for people. Or at least open the discussion again.

lvterry Posted November 22, 2009 Share Posted November 22, 2009 Thanks a lot. This works for me. I am able to use 1680*1050 now =) Link to comment Share on other sites More sharing options...
fraggle65 Posted November 23, 2009 Share Posted November 23, 2009 Hi there, now finally, I got QE working using your method - thanks a lot! Anyway I still can't get over 1400*1050 in resolution while my screen supports 1680*1050 natively. There is also no way to change the resolution, so any help appreciated for that last issue! What to put into /Extra directory? Any specific settings to do or not to do? BTW - I'm using this with Snow Leopard 10.6.2 on a Dell Inspiron 6400 ;-) Link to comment Share on other sites More sharing options...
kavis Posted November 24, 2009 Share Posted November 24, 2009 Does it work with native 1440x900 - 17 inches (16:9) - DELL 9400/E1705? Cant try now! Link to comment Share on other sites More sharing options...
dong Posted November 25, 2009 Share Posted November 25, 2009 People trying RadeonHD.kext for resolution problem should look at my original post here: http://www.insanelymac.com/forum/index.php?showtopic=190586 Link to comment Share on other sites More sharing options...
kelvint Posted December 5, 2009 Share Posted December 5, 2009 Does it work with native 1440x900 - 17 inches (16:9) - DELL 9400/E1705?Cant try now! Confirmed working at 1400x900 on Inspiron9400 with ATI X1400. I just installed iAtkos v7 and installed the two kexts mentioned above. By the way, great work by the author of the modified kexts! I did notice some mouse tearing. The fix is to install "Mouse Locator v 1.1". Just follow this link for instructions and downloads: (http://silvertang.site90.net/mousetear.html). Don't forget to place the MouseLocator.png file in your pictures folder. Good luck. Link to comment Share on other sites More sharing options...
ss_insaneguy Posted December 5, 2009 Author Share Posted December 5, 2009 Hi kelvint, thanks for the tip regarding mouse tearing! Looking forward to trying it. And I'm glad to hear the x1400 is now working for you. Link to comment Share on other sites More sharing options...
kelvint Posted December 6, 2009 Share Posted December 6, 2009 It is working at 1400x900 but periodically, I get panic kernels at startup and at shut down. After a few reboots, it seems to be fine. Any remedy ideas you could suggest? Thanks. Update: Just followed the link above by Dong and used the 10/28/09 RadeonHD.kext. Full 1440x900 without panics. Thanks Dong.

voxelized Posted December 12, 2009 Share Posted December 12, 2009 Can also confirm this works on Snow Leopard with a X1400 card. Link to comment Share on other sites More sharing options...
rpdmatt Posted December 18, 2009 Share Posted December 18, 2009 I'm having a lot of trouble getting this to work with 10.6. I'm wondering if I should uninstall the other ATI kexts in order to get it to work, I remember having to do that with my GTX 280 on my desktop computer. If anyone could elaborate on anything they might have done differently to get this working with 10.6, I'd appreciate it a lot. Link to comment Share on other sites More sharing options...
WandaL Posted December 23, 2009 Share Posted December 23, 2009 this guide rocks!! Thanks to you, now I have Full res (1280x800) on my ATI Mobility X1400 card on acer aspire 5672 running OS X 10.5.8. I have mouse tearing though after full res. Will work on it now. Link to comment Share on other sites More sharing options...
super_engine Posted December 26, 2009 Share Posted December 26, 2009 Good news for all peoples The last version of RadeonHD.kext (18 dec 2009) Dong (my big hero) have fixed the mouse tearing and the driver is very more stable (no KP) Download it from ATI Framebuffer section. Good luck. Link to comment Share on other sites More sharing options...
rpdmatt Posted December 27, 2009 Share Posted December 27, 2009 Thanks super_engine, that's exactly what I've been waiting for. It works flawlessly in iAtkos 10.5.7, I might try it out on Snow in a bit to see if I can get it working there, I wasn't having much luck with the last release.
