Okay so i have been trying to load mavericks on my Lenovo G400s Touch. 

 

I have got mostly everything working with a great battery backup of around 5 hours incredibly :P

 

The problem i am facing is with my HDMI Out....i m using 10.9.4 and 10.9 at the same system... help me out with anyone :)

 

I have i5-3230m with HD4000 graphics of around 2GB according to windows but on mac i get only 1GB, thats not a big issue.

I have Insyde Bios which i am sure is only giving out stolen ram of 32mb because it works flawlessly when i inject any 32mb platform with LVDS connector port configured as "05 03 00 00 02 00 00 00 30 00 00 00 " for low resolution of 1366x768. (on 64mb it gives garbage lines all over screen with movement)

 

But i am getting difficulty in using HDMI out. i tried platform-ids of original 3,4,8,9,10,11 and also with replacing LVDS connector ids.

But only 0503000002000000030000000 gives full acceleration and only on 32mb.

 

I cant flash my bios, so please help me to either patch my platform ids to 32mb or any way to fix my hdmi port with any other already 32mb platforms i.e 4,10 and 11. 

 

Please help....
