No trackpad/keyboard/usb after install

Hi everyone. First thank you to everyone who helps make all of this possible. I have been working for months (off and on) to get OS X on my laptop HP DV7-6b75nr and could get it to install fine but never boot! I've finally gotten it to boot after installing using iATKOS ML2 and the right set of options. And i did buy mountain lion so please dont ban me.

 

 

So now here's my biggest problem. The trackpad and usb worked during installation but not after.

 

I can get it to work if i boot in to safe mode but thats it.. USBBusFix and EHCIhard do not fix it. Neither does -f, -F, pciroot=1

 

I got to this point this morning, then totally hosed everything when I tried to fix it using chameleon wizard (i think, i dont remember honestly, I'm doing this on my desktop also at the same time), and had to spend all day just to get back to this point again, so now that its working, i dont want to go further alone.

 

Specs on the laptop

HP DV7-6B75NR

i7-2670QM (only showing 1 core)

HD3000 (working)

RADEON 6770M (detected but not working, later issue)

16GB RAM

USB 3.0

Fingerprint scanner

WIFI intel centrino N 1030 + bluetooth & WiDi (none of it working obviously)

card reader

VGA+HDMI

DVD-RW/Blu-Ray player (CD-RW portion works at least, i successfully burnt a disc)

installed to a dedicated drive (tri booting off ssd & hdd my goal)

 

..I know most of that will never work

other issues that might help figure this out:

 

Laptop display does not show anything after boot.. It works during install and boot but not once you get to the desktop. HDMI works. It can sense the display because at first, it'll be in extended mode till I close the laptop and it switches the desktop to HDMI only.

 

It crashes after about 10 mins of running.. The fan is working. When you go to shutdown the laptop actually powers off (unlike my desktop)

 

no sound

 

 

The attached ZIP has the bootloader log file and an exported dsdt. the screenshots are of devices and their IDs

 

I'm guessing i need some kext's or to edit them.. I know where they're at on the system and how to edit them, if someone can tell me exactly what to change.

 

Please help me out. Thanks immensely in advance

is very simple, why you use this boot flag? npci=0x2000 cpus=1 busratio=22 -x

 

with -x don´t read your kexts for it

 

 

 

read it first:

 

02. BootHelp.txt:

 

The boot: prompt waits for you to type advanced startup options.

If you don't type anything, the computer continues starting up normally. It

uses the kernel and configuration files on the startup device, which it also

uses as the root device.

 

Advanced startup options use the following syntax:

 

[device]<kernel> [arguments]

 

Example arguments include

 

device: rd=<BSD device name> (e.g. rd=disk0s2)

rd=*<IODeviceTree path> (e.g. rd=*/PCI0@0/CHN0@0/@0:1)

 

kernel: kernel name (e.g. "mach_kernel" - must be in "/" )

 

flags: -v (verbose) -s (single user mode),

-x (safe mode) -F (ignore boot configuration file)

 

"Graphics Mode"="WIDTHxHEIGHTxDEPTH" (e.g. "1024x768x32")

For VESA 3.0 graphics, you may append a refresh rate

after an "@" character (e.g. "1280x1024x32@75")

 

kernel flags (e.g. debug=0x144)

io=0xffffffff (defined in IOKit/IOKitDebug.h)

 

Example: mach_kernel rd=disk0s1 -v "Graphics Mode"="4096x4096x32@85"

 

If the computer won't start up properly, you may be able to start it up using

safe mode. Type -x to start up in safe mode, which ignores all cached

driver files.

 

Special booter commands:

?memory Displays information about the computer's memory.

?video Displays VESA video modes supported by the computer's BIOS.

?norescan Leaves CD-ROM rescan mode.

 

Additional useful command-line options:

config=<file> Use an alternate Boot.plist file.

 

Options useful in the com.apple.Boot.plist file:

"Boot Graphics"=Yes|No Use graphics mode or text mode when starting.

"Quiet Boot"=Yes|No Use quiet boot mode (no messages or prompt).

Timeout=8 Number of seconds to pause at the boot: prompt.

"Instant Menu"=Yes Force displaying the partition selection menu.

 

"Default Partition" Sets the default boot partition,

=hd(x,y) where 'x' is the disk number, 'y' the partition number.

 

GUI=No Disable the GUI (enabled by default).

 

USBBusFix=Yes Enable the EHCI and UHCI fixes (disabled by default).

EHCIacquire=Yes Enable the EHCI fix (disabled by default).

UHCIreset=Yes Enable the UHCI fix (disabled by default).

 

Wake=No Disable wake up after hibernation (enbaled by default).

ForceWake=Yes Force using the sleepimage (disabled by default).

WakeImage=<file> Use an alternate sleepimage file

(default path is /private/var/vm/sleepimage).

 

DropSSDT=Yes Skip the SSDT tables while relocating the ACPI tables.

DSDT=<file> Use an alternate DSDT.aml file

(default paths are /DSDT.aml or /Extra/DSDT.aml).

 

SMBIOSdefaults=No Don't use the Default values for SMBIOS overriding

if /Extra/smbios.plist doesn't exist, factory

values are kept.

 

Rescan=Yes Enable CD-ROM rescan mode.

"Rescan Prompt"=Yes Prompts for enable CD-ROM rescan mode.

Hi guys thanks for the help. I have learned a lot over the last 24 hours.

 

Sorry I had forgotten to post that I resolved most of my issues with the right kexts, pulling my DSDT using the editor, then patching it with a file that closest resembles my laptop and putting it in the right location.

Currently working:

Internal screen

keyboard

trackpad

usb 2.0

hd3000 graphics

battery

 

I ordered the

TP-LINK TL-WN725N Nano Wireless wifi adapter since the centrino will never work.. or so i read

 

 

I still can't get the sound working.. I've put in the voodoohda.kext, removed applehda.kext, put in the right device and vendor id, but nothing.. but at least it's not giving me a kernel panic :-)

 

 

 

@ifire thank you for the explanation of the boot flags. I was able to boot with -x and get usb working again, but not trackpad/keyboard

 

@minus_13 you were right, it wasn't in the right location. Actually there was no DSDT.aml file, the one I had attached was one I pulled using one of the utilities when i was still having to boot in safe mode.

 

And thank both of you for being the only ones who responded on four different fourms :-)
