Hey, ive finaly managed to install os x on my laptop however, now after the install has completed and it restarts it gets no thurthter than the 10th ish line "using ACPI RSDP revision 2 found at 0x000f81e0"
prior to this i had a HFS+ partition error. i dont know if this is related. Please help! thanks Levi

Not sound rude or anything but...

What's your hardware? What version of the distro did you use? What kext/drivers/fixes did you install? What kernel did you pick?

When you first start up are you trying the -cpus=1 thing if you're using a dual core processor? Are you on Intel or AMD?

I can't really offer any good advice but I can tell you from experience here by reading that if you don't list your hardware and as much information as possible, your thread is going to end up at the end of the list and probably never answered. Chances are you still won't get an answer regardless of how much information you provide simply because the guys who know what they are talking about are busy. Think of it like this, if you have 10 guys here who know what they are talking about and 2000 who are asking for help...well...it'll probably take a while to get an answer won't it?

List your spec's and as much detail as possible and maybe someone can give you some helpful advice. Good luck!

Acer Aspire 5535,
3GB ram
AMD Athlon x2 64
ATI Graphics
dual booting Windows 7and 1/2 working OS X
i used the chameleon patched Kalyway 10.5.2 intel Amd DVD for install, when through perfectly.
Installed the OS onto a partitioned drive, (formatted the partition correctly and installed fine, no errors.)

After install completed it asked for restart, i ejected the disk and no luck, (had already sorted out the dual boot with my windows 7 using the chain0 file and easy BCD.

When laptop boots the boot screen comes up and the list of os', when i select OSX it does to the countdown, during which i have to press f8 or it does back to the os selection screen. after i have pressed f8 i am offered a list of HDDs. i select where i installed OS X (onto my OSX partition, hd(0.3) OSX ) The message then comes up below "Press Enter to start up darwin/x86 with no options, or u can: type -v and press enter....... advanced startup options
boot : _
ive tried many combinations here with -v, -x, -s, cpus=1 with no luck.

Darwin/x6 boot v5.0.132

after this the _ cursor justs sits there flashing...
thanks for help , hope this information is slightly more helpful. thanks for your time

I wasn't trying to be rude or anything, so I hope you didn't take it that way.

I'm not sure what you should do or what to tell you to do to try and solve your problem. But having it listed that way, I'm sure someone else who has the knowledge I don't can probably answer your question better.

You tried the -cpus=1 thing and you said that didn't work. Somewhere on this forum, I think, I posted about having problems after install too. Seems like someone told me to try platform=acpi or something like that. There was another option also but I can't recall off the top of my head what it was. It might have been on the insanely mac forum and not here, as that's the only other one I hang out on hunting solutions to my problems.

I had to go through about 5 different distros until I got one that would boot back up after install. And that required that I reinstalled it a few times until I got the right combination. I can't recode errors or anything so I can't tell you what you should try to change during your next reinstall. I've never figured out how to change things within the install using the command console, so that means I have to reinstall. But I finally did get it working and only have an occasional kernel panic every now and then.

I got my successful install on a Dell 2200 with an Intel processor. I've also got an HP laptop with the same processor as yours and I have the same issues you are having as well. I can't tell you the number of installs I've done on that machine that are successful and then it won't reboot. I've never seen the welcome video on that machine, let alone the desktop.

Thanks for your help , ill give that a go best of luck with ur HP seems more of a trial and error process i had to go through about 7 different vertions of OSX before i finially got 1 that loaded to the installation
Nice to hear from u, Levi

Just tried platform=acpi, No luck ... oh well.. will keep looking, thanks for your help anyway

I was told to try :

-cpus=1 -v -x -f platform=acpi idlehalt=0

Try that or a combination of that and see if it works for you. I actually got a little farther today with some crap about PS2 or something. I don't know. I've reinstalled on this HP so many times that I've forgot what I've picked and what I've not tried yet.

Stuff like this is a simple way of saying "buy a real Mac"...hahaha.

haha went into the mac store yeterday lol ... went on macbook pro 13"... was nice :L but not worth £900 much rather spend else where... ill give that a go now, thanks for your help
(i also use to have that trackpad error.. ) in the end i went for... u guessed it.. another disk! lol

Juat gave it a go :/ no luck...
was like :O it might work lol as mine is kind of at an idlehalt lol oh well lol nvm... tyvm for ur help

I have been looking around and ive finally found out what i think my problem is.

i tried using the the same iso file i used to install but without the Kalyway-10.5.2-Chameleon-1.0.11-JMicron-fix and i got the same error. as i have now its installed.

so.. i figured if i could installl this patch to the HDD then it would load fine. if anyone could help me i would be very greatful. thank you.

For anyone with the same ish problem, ive kept going and have passed this error, i booted to the disk and then got it to boot from the HDD using... yeah.. :S

anyway...

Ive finally got it so it starts up mac (no welcome video) and setup gets stuck in the loop around the file transfer ... seems to be endless problems with this... i cannot use the normal fixes as i no longer get the option to enter -s etc...
Any help would be useful, so close .... yet so far

Fixed that too now have working OS X on my acer 5535
still to fix;
- wifi
- lan
- audio still bit dogie
- graphics - has detected my graphics but has no kext yet

BUT STILL.. Whoop
