It took me a lot of time and reading to figure out how to install Mac OS X on my HP laptop , This forum and several other forums helped me a lot , special thanks for "icchansan" as i found his reply to messages and topics so useful ,
so i ll start by what u need .

-HP pavilion Dv5 with nearly similar specs
-Intel core 2 duo P8400 2.26 GHZ
-IDT sound card
-Nvidia 9600m graphics card
-intel 5100 wireless card ( not working )
-4GB Ram
-Integrated 10/100/1000 Gigabit Ethernet LAN

- Ideneb 1.4 ISO ( 10.5.6 ) found on many famous torrent sites

- Empty 4gb DVD to burn the IDENEB ISO

[info]
- i Tried this guide with an existing install of Windows 7 32 , my friend tried it on an existing install of vista 32 , so yes you can dual boot

- Empty 20GB NTFS drive ( actually u can choose from 10GB to what so ever ) but 20GB is good enough BE SURE THE DRIVE IS PRIMARY .

- Recovery CDs just in case something happened so u will be able to restore ur mbr.

- files you may need RapidShare: 1-CLICK Web hosting - Easy Filehosting
Password for extracting : beige
includes Realtek ethernet lan driver , IOUSB Family fix, NTFS writing solution , chameleon ( a GUI solution for booting )

lets start with the procedure :

- make an MD5 check for the ISO to be sure its not losing any bit of data

- Burn the Ideneb ISO file at low speed

- Backup your DATA ( just in case something happens )

- Restart your computer and go inside BIOS by pressing esc i think , then go to booting options
and make your CD rom higher in priority than your hard disk , save and exit

- Put your Ideneb DVD inside your computer and the computer should boot from it , if it did not press esc and then press F9 (booting options ) i think and choose cd rom

- You will find a CLI counting 5 4 3 2 1 press any key while its counting to start installation

- IF UR COMPUTER STOP AT This screen

, restart ur computer using hard shutdown ( press power for like 5 sec till it force shutdown ) , when booting from CD 5 4 3 2 1 leave it until u find a command line type -v if the computer stops at the line waiting for root device i am sorry to tell you i have no solution but please provide me with your hard drive type and your BIOS type as i am collecting data about this issue with this laptop maybe we could figure it out

N.B: i can't remember the order of the steps 100% but i am sure u will figure them out

-After the apple logo ( 10 min to 20 min i think ) u will be asked to choose language , choose english

continue

- agree


-go to utilities in upper task bar and choose disk utility


- choose the empty NTFS partition and on the right hand side go to erase menu and then choose
mac os extended journaled name : Mac OSX and click erase


-choose destination ( Mac OSX ) , continue


- know in install summary screen choose Customize this is very important as it instals kexts and fixes that will make your laptop work

i think are free to choose more , but this is what i chose .

- The hard part is over , click done and install, then click skip checking


-wait till installation is done , as the computer restarts and after the Hp logo put ur finger on the eject CD button don't remove untill u see the countdown starts 5 4 3 2 1 as soon as u see the 5 keep clicking the eject until it ejects before the 1 this will avoid booting problems
if u saw MBR FAILED , BOOT ERROR then u did not do it in the exact time the "5" if u booted inside the Mac OS then you r 99% done ,

-check this page it will guide you till you reach the desktop
