Thread: Dell inspiron 1525 Lion installation

Need some help getting Lion installed on my Dell 1525, running snow 10.6.8

What are your full system specs? I cutter a huge corner on mine to install Lion easier by performing a CPU swap from a T29xx to a T3400 from my Inspiron 1545 that has a gma x4500m video card in it, where as the 1525 though older, has better video card support, which is why I made the jump back to it for OSx86 use. Other hardware mods i did to this machine was to give it the 1545's 250GB hard drive, and maxed out the RAM at 4GB's instead of 2gb's.

From there, legal install of Lion is preferred method of acquiring Lion, as my first attempt, I ended up with a sour copy of Lion from the little green demon, that would always freeze immediately with the spinning beach ball after the first boot wizard had me choose country and keyboard selection. I tried everything that I could think of. Various kernel flags etc. I tried different boot loaders, Chameleon 2, RC3...Rc4...RC5...various builds of RC5, ...PC EFI 10.6, 10.7, etc...Finally what worked for me best was Chimera from TonyMacX86. You also NEED to use next wizard or next helper to install to Lion's /System/Library/Extensions folder the following kexts: AppleACPIPlatform.kext - IO80211Family.kext - IOPCIFamily.kext - all from your Snow Leopard 10.6.8 install. You will also need after the install to install to your post Lion installed partition all of the above to the same folder, plus IOACPIFamily.kext. Your DSDT.aml file is always a bonus...You'll want your com.apple.Boot.plist set up with something like mine copy and pastest below, along with my smbios.plist respectively. You will also want to run Extra Lion on both the install drive and your final install partition too.

I won't post an exact how-to, but if you need more help, or anyone else for that matter, then shoot me a PM, or post back here, it should email notify me to check as I don't read the forums that often here.

If you are not able to do a CPU swap btw, then you'll need to come up with a Darwin 11.0 legacy kernel some where. And most important tip of all -

MAKE SURE YOU BACK UP YOUR SNOW LEOPARD INSTALL IF YOU CAN'T USE MULTIPLE HARD DRIVES AND USB THUMB STICKS AND ENCLOSURES, ETC, TO MAKE IT EASIER FOR YOURSELF...! Can't stress that enough.

I dont have audio, on my lion 10.7.2 can you tell me kext for that, on my dell 1525

hi goksi75, did you tried Voodoohda?

Hey, I always find AppleHDA to be unreliable out of the box so I had it going with VoodooHDA - but had to manually select the output device in system preferences when swapping between using my built-in speakers, or using headphones. Just experiment in the sound preferences under the output section and just click on each device listed while you have sound say from youtube or iTunes playing and it should just cut in as you hit the right one respectively for speakers and headphones. Headphone testing of course you need to plug your headphones in and listen for them but meh. Minor detail.

Also - as an update to my previous post - I'm sorry I didn't make it back here sooner - but I did get QE/CI working in full 100% on my 1525 along with everything else - now unfortunately I have since wrecked (destroyed really) my 1525 and smashed the LCD, so I'm working on trying to secure some replacement parts from my brother who also has a retired 1525, and I can use it to repair mine. Once back up and running, I can quickly retrace my steps and post a update on how to get full QE/CI working. A lot changed from my previous post, so watch for that. If someone can just keep spamming this thread every couple days to ask for me to update it as soon as possible, that'd be great to have a definitive guide. Maybe try to get it upped to some place like dailyblogged or macyourpc or wherever.

Cheers.

Yes but after Voodoohda I have KP

Use instructions on this thread to fix KP with voodoohda.kext:

Hi,
try this "How To", with the supplied DSDT it will boot.
How to install Lion 10.7.0 on Dell Inspiron 1525 - nozyczek

The Reason why it won't boot is explained here:
[TEQUILA-FIX] GraphicsEnabler, Black Screen and PCIRoot Fix for Chameleon - InsanelyMac Forum

You need the line with _UID in the PCI0 device in the DSDT to boot up. The fix is already applied in the DSDT from the above link.
