Well, after reading the post I decided to wipe the entire drive on one of my Sony's and now it requires the dongle to work.
I've got some new help from BuildSmart, a good programmer, he should be joining in the next couple of days (he says).
I tried to use Ghost to backup the partition but it fails with an unrecognized partition type 312h.
He tried to mount the partition and was unable to find a way to mount it for examination so he took a different approach.
He was able to use a disk editor to scan the partition for content and this is what he has been able to determine so far.
1) the new sony/dell lcd driver is a modified GMA900 driver which appears to be generated from source and not by editing/hex-editing the original GMA900 binary/plists files and it includes drivers to mount this unknown partition
2) the new GMA900 driver is 11.7mb in size which concludes that it wasn't manually edited unless someone spent some considerable time which is highly unlikely due to the structure and size of the code.
3) the unknown partition has a sector size of 512bytes (not including the sector header information which appears to be something non-standard)
4) the new GMA900 driver mounts the unknown partition, executes a binary which resides on it and unmounts it
5) the binary while loaded remaps the video driver temporarily during the boot process into believing the LCD is connected on the VGA port.
6) when the login window is executed it re-initializes the video driver using the default or assigned screen resolution which restores the original video driver and removes the program that was loaded from the unknown partition.
7) it was coded in this manner as an easy solution because it is simple in design but makes it impossible to duplicate without the source code or the application that was specifically designed to create and install this partition and it's binary.
8) the person who wrote this code is without a doubt an Apple employee who is paranoid about getting caught.
9) if enough information and source is obtainable, he believes he may be able to provide a solution in a single driver without external dependancies
Upon further conversations with the person who programmed this, it seems that besides myself and a handfull of people who have it installed (but do not have the DVD), only one person has a copy of the DVD and he is also an Apple employee
who doesn't want to be associated with this movement.
BuildSmart believe's he can obtain the source for the 10.4.7 mach_kernel and if he could find out what changes are made to get the 10.4.4 kernel working for Intel and AMD processors he can modify the kernel source to work with both thus generating a single kernel that would work for everyone.
He also believes that if people like JaS, Myzar and SemaJaZa would get together with him, they could as a group provide a much cleaner installation process which has significantly less installation issues.
We also discussed the multiple 10.4.7 updates and he says that only a handful of files in the JaS and MyZar 10.4.7 updates are actually modified or swappedso he believes that these can be combined in a single package leaving a single checkbox for the CPU type making installation easier for the end user to obtain a working solution while reduing the size of installed files.
He states the concept of the replace.sh script to do the update while works, is a poor implementation and is not a process that should be left to the end user.
After seeing some samples of BuildSmart's work, I am convinced he can be very beneficial to this project but as he states, it will only be really successful if collaboration occurs.
Basically as I see it, it's up to the people I've listed (and Maxxuss if he's around and reading) to take this project to the next level otherwise there are going to be too many variation of the installer DVD floating around that don't work for everyone, are not as easy to obtain and have too many unresolved installation issues.
I have already started remapping the installer DVD to be more efficient and versatile and have added some additional installation applications and his opinion is that I am moving in the right direction.
I have asked people for their modified drivers so I can add them to the installer DVD but have not recieved any responses which leads me to believe that those doing the installation are only interested in getting it running on their machine and not interested in helping the cause.
This leads me to my final conclusion, if some kind of collaboration and assistance doesn't start to happen soon, then I'm going to be forced into giving up helping the cause and only worry about supporting my own machines and work with BuildSmart to resolve my Sony/Dell LCD issues and the sad part will be that this stuff wont get shared with anyone.
