I have started delving into the new f4e bios and DSDT.
- First, this DSDT has by far the most warnings i have seen in any DSDT during compile. Some of the warnings i don't see common solutions for. I am working through as many of these as i can.
- There is one error which is preventing me from doing a proper recompile. I could force recompile but it bothers me that there is an error (again, i can not find a common solution for this one). The error is:Return (NVH7 ()) Error 4060 - Called method returns no value ^This seems to be in the onboard video section of the DSDT, hmmmm.
- I am looking through Koalala's older dsdt for some hints. It appears that he greatly expanded the onbaord video section of the DSDT. This is also the section with the aforementioned error. I could simply duplicate his additions to this section but it has at least occurred to me this might not be a good idea for a couple of reasons: A) there might be incompatibilities between versions and can we say for certain that these additions are not causing the 4GB error to begin with?
I am eager to get this working and so i will be trying some actual tests as much as i can. But it is looking as though working through some of these issues may take a lot of time and testing and i am hoping some others on this thread will be able to help test and lend ideas based on these findings.
The video ram problem was experienced before Koalala started patching. That line comes from the original bios and existing in the new bios as well. Also, Blueknight has patched that particular line is his SL dsdt and it has not fixed the problem, but then maybe the patch is incorrect.
I am not surprised that the gigabyte fixes aren't working since the dsdt in the bios they sent is clearly not ready to be interpreted by OSX. I have been working on merging koalala's dsdt.dsl and the one extracted from the new gigabyte BIOS which I ran through Koalala's patcher. I got one that I think has not quite the minimum changes from koalala's (plus the rtc cmos fix and bluenight's NVH7 fix (which I wish he would explain). I patched the new bios with the DSDT and my 10.5.8 ide install won't boot past the OSX spinning circle (the screen grays out and the "you have to shutdown" message comes up), however the same BIOS does let me boot my SL DVD via a chameleon bootCD and I am trying an install right now.
I also intend to try to get the dsdt diffs down to what look like the minimum memory map changes and try that with 10.5.8.
Will posted the results.
