kevintroy Posted December 13, 2010 Share Posted December 13, 2010 I have a Compaq Presario SR5129UK which I've added a NVIDIA 9500GT 1GB graphics card into in aims of installing either Leopard or Snow Leopard onto, but I have a bit of a problem... When i go into my BIOS I have no option to change to AHCI mode, which I believe is needed to run Leopard or SL? I've tried to install iDeneb and iAtkos onto my system but neither will load, I get a "stop sign" on the grey screen after a few minutes, I've also tried to install both via Virtualbox but neither work (iDeneb installs but after i unmount the CD to restart after installation, it goes to a blank grey screen and hangs) What are my options? here are my computers specs (screenshots taken from CPU-Z): Compaq Presario SR5129UK CPU Caches Mainboard Memory Graphics massive thanks to anyone who can help me!

mikeper94 Posted January 3, 2011 Share Posted January 3, 2011 That's strange, I have exactly the same computer but with a 9600gt gfx card instead and although I couldn't get OSX working with one hard drive, I definitely had the option to change to AHCI within the BIOS. Just to confirm, is there an option called "SATA Mode" on the first screen that appears when you enter the BIOS setup? If there is then that's where you need to be choosing AHCI. (If the option isn't there it might be worth checking if you have the most up-to-date drivers for your hard-drive.) Before you change the SATA mode however, remember to enable AHCI mode in windows 7 otherwise you'll have to go through the painful boot recovery process to make it work again. Do that by following the guide here. If you can get it working on a second partition then congratulations. I personally couldn't, but I did get it working perfectly when I installed on a second hard drive. Hope this helps Mike Link to comment Share on other sites More sharing options...

Hope this helps Mike Hi there, I've checked my BIOS again and the only similar thing I have is Onboard PATA/SATA Drivers which include the following: PATA Controller - Enable or Disable SATA1 Controller - Enable or Disable SATA2 Controller - Enable or Disable I've checked the Compaq website for driver updates but I see none for the BIOS when I choose windows 7, however, if I say that my OS is Windows Vista (which originally came with the computer) then I get the following BIOS update: P5LP-LE Motherboard BIOS Update Description:P5LP-LE Motherboard BIOS update corrects SATA port information displayed in BIOS setup. Im guessing this wont work because it says that I must have Vista and be logged in as administrator to install the update. Also, what version of OSX were you using? iAtkos? iDeneb? etc etc? I was looking to preferrably get Snow Leopard but if not possible then I can stick with OSX Link to comment Share on other sites More sharing options...
