#1927939 HD 5450 on Mavericks

Posted by Dradis on 26 June 2013 - 01:56 AM

Just had a similar problem with my 5750, hope my solution also works for you.  First make absolutely sure that you have the correct device ID (sorry if that goes w/o saying).  Putting it in ATI5000Controller.kext should give you full resolution support.  Putting it in AMDRadeonX3000.kext should give you QE/CI support.  In AMDRadeonX3000 there are sections for various graphics card families or code names.  Be sure to put you DevID in the correct section.  Your card should go in the AMDCedarGraphicsAccelerator section.  (I do not have this card, so I cannot verify that it is Cedar).   Also, I don't think your card is a natively supported card, so you may need GraphicsEnabler=Yes.  Try both Yes and No. I hope there's something here that you haven't tried yet.  Good luck.

#1826836 Asus P8P67-m Pro DP4 guide

Posted by Dradis on 14 June 2012 - 07:51 PM

I have just successfully set up Mountain Lion DP4 on my Asus P8P67-m Pro and decided to share what I found with the community. I used a patched version of the latest BIOS (3602) along with the DSDT and SSDT for that version. A modified BIOS is not necessary but should help with speedstep and sleep, and NullCPUPowerManagement will no longer be needed. By using this method I have gotten everything working except sleep (but its close). I found all of this information here and on other forums. I am in no way claiming any of this as my own work, I am simply bringing it all together in one place. Things you will need:A working install of OSX Lion or Snow LeopardA spare USB flash drive, USB hard drive, or internal hard drive (at least 8GB)A copy of Mountain Lion DP4 (Please don't ask me for it. I'm assuming you are a registered developer)Lnx2mac ethernet driver (get it here http://lnx2mac.blogs...osx-driver.html)A mountain lion compatible chameleon boot loader (get the pkg...

#1826652 AMD Radeon problems DP4

Posted by Dradis on 14 June 2012 - 04:51 AM

Installed DP4 with little trouble, but i'm still having this graphics issue. Basic low res was working out of the box, then I added my dev id to ATI5000Controller (68be, ati 5750). I've got full resolution but no QE/CI. I tried also adding my dev ID to the AMDRadeonAccelerator.kext just as a guess. No effect. Any more ideas? I remember the days when Mac OS would scale down the eye candy for machines without QE/CI. Now it just laughs at you. Just FYI, I first tried to use my ATI5000Controller from 10.7 since the dev IDs were already there and it worked so well in Lion. Doesn't work. 10.8 requires a newer driver. Fixed my problems :) I have full QE/CI. How did you achieve that? Did you have installation issues i.e. white screen? Also, which card do you have? Second that. How did you fix it? I'm not trying to be rude, but it really helps no one when you say you found a solution, but then don't share it. EDIT: SUCCESS Adding my devID to AMDRadeonAcc...

#1588892 Can I change my monitor's splash screen?

Posted by Dradis on 22 November 2010 - 12:47 AM

I don't know if this is even possible, but it sure would be nice. I have a Gateway XHD3000 and when I turn it on I am greated by a Gateway logo for about 3 seconds. Needless to say, this is the last thing I care to see. I know this image is stored in a ROM chip or something inside the monitor. Is there any way to flash that to a different image? I've tried to google it, but found nothing. Maybe I searched the wrong terms, or maybe it just can't be done. Anyway, if any of you programer/hacker types might know how to do this, please share. Thanks.
