My first post here and it is to ask of some assistance, sorry! (Like the pass quiz to post idea, great idea!)
After a long struggle I have installed Mountain Lion 10.8.2 on my Sony Vaio E Series (2012) laptop (SVE1711X1EB), I had to replace my wifi card but I have got most other features working. I will gladly post a guide for others to use when I can get my graphics acceleration to work. Would really appreciate some help with this.
My specs are:
Laptop: Sony Vaio E Series (2012) - SVE1711X1EB
CPU: Intel Core i7 3612QM
RAM: 8GB DDR3 1600Mhz
GFX: Intel HD4000 Integrated Graphics
GFX2: AMD HD Radeon 7650M
SSD: Corsair GTForce 90GB (Primary and has dual boot with Win8)
HDD: WD 750GB 5400RPM
Screen: 1920x1080
WiFi: Atheros AR9287
I Can't get Graphics Acceleration to work
I think either need a way to disable my ATI so that I can run GE=Yes or I need to get my HD4000 to run with GE=No (I think). I have tried all of the HD4000PlatformIDs (0-9,a, b ) and I've tried some EFI string injections, I can't inject a string that I generate myself with gfxutil as I need to get my device ID (right?) which isn't loaded in IOReg. The biggest downer is that I can't set my VRAM in the BIOS.... I do not have a modded bios and I'm pretty locked down. I have requested a bios mod but not much seems to be happening with it. My Video memory is displayed at 7mb
Is it possible to modify my VRAM in my DSDT? I'm currently not using a DSDT but I have extracted mine before and I have successfully booted from it. I've tried changing the GFX0 fields to IGPU as aI read somewhere that it could work, I did boot ok with it but sadly, no QE/CI.
Speaking of DSDT, can I disable my AMD card in there? If so, could someone point me in the right direction?
I have hunted around the web now for what seems to me like decades (realistically it's probably about 2 weeks), followed all the main guides (stuffed cow blog, tonymac, macbreaker etc)
So, can anyone see a way around my problem? Or am I stuck without QE/CI until I get a BIOS mod?
Many Thanks
