Install time

Here we go, installing Leopard with the Kalyway 10.5.2 DVD.


Keep copies of EVERYTHING on either a DVD, or on a USB thumb drive. More than likely you will be installing MANY times until you get it just right. Label everything, and keep it close. Every time you reinstall, erase the partition first (In Disk Utility). It's always best to start fresh and keep notes along the way.


Picked pretty much the default settings except for Video driver, I picked NVinject for the 512 meg VRAM card.


It installed pretty easily, no hiccups. The first problem on restart was that it wasn't QE/CI capable. Now this is pretty much the biggest job I had to do so far, figuring out how to get QE/CI to work. Essentially, I have the right NVinject choice from the original install. The problem actually lies in the card itself, it needed to be reflashed!!


The vendor ID on this card is 0x10de, and the device ID is 0x0393.




To reflash the card, you will need a DOS bootable diskette, and a utility called NVFLASH. The details on this step can be found here: http://nvinject.free.fr/512Mb.html (you can get updates to NVinject at this site too if needed)

This is a scary step to take, but in the end, it wasn't that big a deal. Just take your time, and triple check your work. You'll need a hex editor, here are some:


for OSX: http://hexedit.sourceforge.net/

for WIN: http://www.physics.ohio-state.edu/~prewett/hexedit/ ( I USED THIS ONE)


Save backups of the ROM dumps as you proceed with the steps outlined in the website. if you have to backtrack, you'll thank God you have the original ROM to go to.


Reflashing the card was relatively easy, but un-nerving none the less.




Setting up NVinject to use my card. There was a LOT of research that went into this, I was all over the place trying to get all the info required (There really should be a GOOD central location for this info), in the end, it only required 2 little changes: the Card ID's and the NVCAP value. The card ID's are easy, go to "About this Mac" and click on the "More Info" button. The Graphics Display entry will be correct. (Vendor and Device ID is what you want). Next, get a utility called NVCAP Maker (Version 1.4 at the time of this writing), you'll need that to extract the NVCAP value from the NEW ROM backup file you surely kept, RIGHT? Now, to edit the NVinject kext, you will need to use "Property List Editor", it comes with the development tools (I got the iPhone SDK). Go to http://developer.apple.com and register as an iPhone developer and get the SDK. (It's Free). The number that NVCAP Maker produces goes into the NVCAP entry for NVinject.kext.. I made a copy of the Info.plist file, edited that, then recopied it to where it belonged. Also, modify the IOPCMATCH entry to use your cards ID's. For my 7300 GT it's 0x039310de'. Make the IOProbeScore 0 after that. My NVCAP number was '0400000000000300040000000000000700000000'. The standard install method applies here.


From a terminal window:

sudo su -

cd /System/Library/Extensions

chown -R root:wheel .

chmod -R 755 .

cd /System/Library

rm -rf Extensions.mkext



When OSX restarts, you will hopefully be fully QE/CI accelerated. Check to be sure, in the system profiler.


This video card was the biggest headache to date. But now it's done.


If all went well, you have a really snazzy OSX box in front of you. Full hardware acceleration opens up the fancy screen savers, try em, they are pretty good. Try out video, and DVD, they will all be smooth as glass.


That's the end of this part, enjoy.
