In Topic: [solved] MSI U100 GMA950 0x27A68086 bufferframe on SL

07 April 2013 - 05:05 PM

The reason seems to be Chameleon Loader. Some change was made with versions( build > 168x). Rollback to Chameleon 1400 and everything seems okay. Will follow this issue and list a tutorial here.

[follow- up]
The keypoint is:

put both 0x27ae8086 0x27a28086 in [iopcimatch] secions of *.kext / Content/Info.plist . It seems one is for framebuffer and the other for rendering engine. Usually you could find 0x27ae kexts from osx86 but don't forget to put 27a2 in iopcimatch as well.

And I used to make use of netbook-installer (google project) but give it up for its unfriendly bootloader. The effective part of this pack is in fact evilappleacpi & eviliopcifamily kexts in Extra directory. Without these two packages you could not reach single user mode, and it could cause other minor issues. Just forget about its (netbook-installer) modules because they are mostly built-in components in ChameLeon's newer versions.

As MSIWIND uses rtk wifi& eth adapters, you have to install realtek pro and rollback io80211family to 10.6.7 to prevent disconnection issues. It is advised to keep 10.6.7 AppleACPIPlatform.kext IOACPIFamily.kext in /Extra directory to overwrite 10.6.8 ones, which might be a coordination for io80211faimly.kext.

Audio is always a problem. But not so big with u100.

In fact I set up two msi wind u100 laptops. This instruction just works.
