GMA 900 (915 chipset and variants)

[troisd]

I spent the entire night going through all the posts in the GMA900 how-to thread. Interesting points made by Maxxuss himself. Got me thinking. I believe I know what is going on and am now in the process of writing code to prove the point.

 

First of all:

 

I'm a Sparc/SunOS/Linux programmer. Sometimes I feel a little lost with OS X.

 

Here's the deal:

 

I need to access OS X memory directly, BUT, Apple decided it was a good idea to remove /dev/mem!

 

I could spend a few days trying to figure a workaround, and that's what I'll be doing, UNLESS...

 

...someone knows how and tells me :-)

troisd, good luck on your quest! I can't really help you with that.

but I am curious - what exactly do you mean by a "solution"? are you referring to the need of faking an external monitor to use video drivers, or are you talking about something else?

 

thanks

Setting VBIOS parameters prior to loading Aqua all done via software.

 

This little project, if it works, would then eliminate the need to use the VGA dummy.

Hey troisd, here is another idea which comes from the following thread:

I thought about it for a while. Instead of coding something within OS X, why not boot up some micro linux distribution, allocate video ram, turn on wireless , set processor speed to highest, etc. and then automatically do a warm reboot into OS X? Some people need to boot into windows firts to get all these things working.

 

just my 2 cents.
