I'll try this. By the way, I am still using AppleHDA.kext from 10.6.2. I tried to patch the one from 10.6.4 but I guess it is not a simple find & replace thing. Then I found another patch for my code id but it constantly produced errors on Console. (Every single second) Would you mind creating one for me?

I think you can keep using 10.6.2 AppleHDA.kext. I read some people recommend using 10.6.2 AppleHDA.kext while other people recommend to patched latest AppleHDA.kext with our codec id. I have to admit 10.6.2 AppleHDA.kext doesn't or if any just produced less errors (this depend on your audio codec compatibility with AppleHDA.kext). On my Dell Studio which have different IDT audio codec, 10.6.4 AppleHDA.kext (patched with my codec id) produced four to five errors in consoles during boot but audio still working, all input & output, auto-switch too. About on how to patched AppleHDA.kext with our codec id, I found out after looking in several legacy kexts for IDT & ALC (Realtek), I came up with this conclusion:-

Quote

ALC Audio Codec:-
- change all 8508EC10 to (for example) 8308EC10 in AppleHDA binary file

IDT Audio Codec:-
- change all 8419D411 to (for example) B0761D11 in AppleHDA binary file

* Check in codec dump to know your codec ID (Vendor ID in endian format)

I think try modify your legacy kext first. If it still doesn't solve your problem, we will try with 10.6.4 AppleHDA.kext.

Hi guyz,
i update you with my problems... i have partially solved them. It seems I have not so many hangs now! I simply changed the smbios.plist, as JBraddock and kizwan suggested me. Now the benchmark is a bit lower, but system seems very stable and i had very few crashes after that! I had just one crash messing with hdmi port(while disconnecting, changing rate, and so on and it never happened again when i tried again). I will investigate further on that. anyway. VGA & HDMI seems to work as external displays! Very nice!
I also changed the bootloader and i have put a meklort older version of chameleon (among the latest ones from the updated trunk) and now my ioreg dump shows AGPM controller!

Here it is my last ioregdump : http://www.mediafire...i96fu13dgm3lyg7

About audio, eerything seems to work properly except that i hear occasionally some loud pops through the speakers.  Mute fix by kizwan is working fine, audio works after resume from sleep. It works also after resume from hibernate, but when i resume from hibernate, i have another problem : USB ports don't work any more after resume from hibernation. I have set hibernate mode 3 and i disabled secure memory and added ForceWake=Yes at com.apple.Boot.plist

So i write down a list of the problems i would like to fix (by myself or with your help). I would like to say that such problem are much less important to fix in respect to my freezes/hangs i had before, but still important for daily use :

- it doesn't go to sleep if i close lid (perhaps i can fix it... i will try and then i will let you know)
- it doesn't go to sleep automatically after a few minutes , as set in power saving preference panel
- disk utility takes a while before i can have access to disks (i see rainbow ball for about 2 minutes, then i can do everything)
- battery meter jumps from 0 to 100 and from 100 to 99 then start charging ... perhaps there is something strange in VoodooBattery. I tried AppleACPIBattery.kext but it crashed starting osx. VoodooBattery is the only kext working.
- audio pops from speakers (quite loud if volume is at maximum)
- SD card reader not working (perhaps i may try some driver i saw here or in other places and will let you know if it works)
- express card not working (?)
- bluetooth not always active after resume from sleep/hibernation. Sometimes it works, sometimes not.
- intel wifi not working (of course ... i do not expect a fix for that, i am waiting for my broadcom wifi card to replace it... i know whitelist problem, insyde bios patching and rewiring in empty slot, i hope the card will be in whitelist)

I will keep you updated. I don't think my problems are gone, but at least is way better than before. I would like to understand more about freezes. I would like to have my system running ok 100% without freezes/hangs of course.

Thanks!

hi Kizwan , i tested your R2 & R3 & R4 & R5

R3 works great (internal speakers,line out, internal mic, line in with both jacks)
but i can't mute i have to slide the volume down to mute and also it don't must when i remove the hedphone

R4 & R5 don't even work with me

thanks for your great work and keep going

Dear Kizwan,

I tested R5, R4 & R3 on my DV7-3085dx. R3 works perfectly on my laptop--automatically switches between speaker and headphone; the volume touch panel works; but the mute switch not working.

The sound quality is much better than in Windows 7, I feel.

Thank you very much!

LID Sleep: See Valv's LID hack if it works for you.
Force Sleep: Use a third party app. It may work. I am pretty sure I read something about force sleep in this forum and saw a few apps but I couldn't find them. Try this.
Disk Utility: Check if your HDD is seen as internal. Open Disk Utility, click your HDD, look below. It should be Connection Type: Internal
When you log into OSX and, say, you have three partitions, and when you see the desktop, do you see all your partitions mounted and ready or just the OSX partition and then the others follow?
Audio Pops: I don't know the reason of this but I suggest, if Kizwan agrees with me, you don't use SignalProcessing for internal speakers. In my case, it reduces the quality of sound in a very noticeable way.
Battery: Is your battery seen as internal? I had the same problem with HDX before applying Valv's hack. I used to have random KPs while plugging or unplugging the power cable.
Usb & Bluetooth: Check your USB fixes in DSDT. May be there are things to be done. Most HP laptops have these problem and as far as I read these are because of HPET conflicts. Especially, left USB port has always been problematic.

Be careful with SMBIOS.plist. I remember set my mac model MacbookPro5.4 and once I started to use a legacy speed step kext, HDX went crazy. Soon I realised that it should be MacbookPro5,4. If you have applied any CPU related hacks, popping sound might be related to that. I don't know about which version of Chameleon you are talking about but use this thread and do not use a special version of Chameleon or a kernel until you make sure that all your problems are not related to Chameleon or the kernel.

[the-patient]

With regards to the antenna repair,

would it be possible to see the link for those cable extensions?  Also what is the name of the connector etc, I would look into making a few custom cables for anyone interested!

Thanks!

Also, a quick question - is there a way to get 2-finger scrolling to work on the HP, or any scrolling for that matter?

Try add LID Sleep Fix in your DSDT. Like this:-

			Name (LSTS, Zero)
			Method (_LID, 0, NotSerialized)

				If (ECON)

					If (IGDS)
					{
						Store (LSTS, LIDS)
						Store (LSTS, ^^PCI0.GFX0.CLID)
					}
					Return (LSTS)
				}
				Else
				{
					If (IGDS)
					{
						Store (One, LIDS)
					}
					If (IGDS)
					{

				// end - LID sleep fix
			}

I believe it is caused by something else. Maybe need to set correct model identifier in smbios.plist. Hard to prove but this maybe caused by improper power management (which also related to wrong model identifier in smbios.plist). On my Dell Studio, I set model identifier to iMac11,1 because it's configuration (i7 & ATI Mobility) almost similar to iMac11,1 specification. I never tried with MacBookPro6,1 model identifier, so I don't know if the pops sound also can happen on my Dell.

It is hard to fix this. On my Acer Aspire 9420, I have 50-50 chances bluetooth doesn't work (turned OFF) after wake from sleep or hibernate. Sometime it take a couple of second before the bluetooth device truned ON. I already put a code to turned ON the bluetooth at _WAK control method but the problem still persist.

I dont think any broadcom cards are in the whitelist, but you can modify the whitelist if you desire.  Take a look at what I posted as a starting point.  It worked perfectly for me.  Let me know if there are any questions!

Is there an a/b/g/n device that we can replace with the intel one? The one that Mammoth used was a full range device, I don't know what that means , and it will not work on my HDX? Am I right?

I've seriously started to think about replacing the Wifi card as I don't think HP will release another bios update for my laptop.

[tical2k]

take a look at http://redirectingat...x...1653&st=260

If the HDX has a 1MB bios follow that guide to remove the whitelist.  If its 2MB,  You can always try like I did and change the whitelist value of your current installed device to the one you want.  I'm going to be getting a a/b/g/n broadcom BCM94322, which I expect to have fully working after i repatch my bios.

Added:  I will have to say that I've not tried the full removal method, I've only done a search and replace of my device id and vedor id with the one i want to use.  Also MODING AND FLASHING YOUR BIOS IS RISKY, attempt at your own risk.

Actually what Mammoth means was full-size of miniPCIe card. New notebook come with wireless card in half-miniPCIe form-factor which actually half the size of the (regular) miniPCIe card. I haven't look closely but actually both cards are using same connector which is miniPCIe. You can try any Broadcom wireless card. Usually you have better luck with broadcom wireless card.

When I take a look in F.25 BIOS I see this list on wireless card white-list section:-

Q.D.S.-.B.R.C.M.1.0.4.3.........Q.D.S.-.B.R.C.M.1.0.1.8.........Q.D.S.-.B.R.C.M.1.0.4.1.........P.D.9.1.1.2.B.N.H.U.....P.D.9.6.3.3.A.N.H.U.....P.D.9.6.2.2.A.N.H.U.....P.D.9.5.1.2.A.N.M.......P.D.9.5.1.2.A.N.M.U..... .......P.D.9.5.3.3.A.N.M.......P.D.9.5.3.3.A.N.M.U

I know BRCM is for Broadcom wireless card but don't know about PD. Intel card maybe because I see "PD" in FCC ID on Intel card. There is also white-list for WWAN card but I don't see any list. Maybe just device & vendor ID in the white-list.

Yes it is risky but there is a way to recover corrupted BIOS with CRISIS disk. I can see in F.25 BIOS package, HP include CRISIS BIOS which I believe for BIOS recovery. I'm not experience with Insyde BIOS only Phoenix BIOS, so I can't tell you about the Insyde BIOS recovery procedure.

Hi kizwan, JBraddock
so do you think i have to check PowerManagement ? May i damage my computer/cpu ? Can you suggest me a smbios.plist to use ? Do you think is it related to something else than smbios.plist ?

To JBraddock : do you have sd card working on hdx18? or did you fix applehda according to the information kizwan told you and/or dsdt and audio in this thread ? if you have news about applehda or other stuff , can you please update it in valv'2 HDX18 thread ?  Thanks !!

Here is the interesting part and look what I found. I've just read my HDX service manual and it seems that there are some HDX models shipped with Atheros AR9280 802.11a/b/g/n, which you may know, is being supported by Snow Leopard.

(via). On this topic I saw a HP user who replaced his wireless card with this model. Clever guy.

Since all HDX16s and HDX18s have almost identical bios I don't see any reason why this card shouldn't be already on the whitelist.
Asus EEE PC 1000HE users have the same card. Snow Leopard 10.6.5 beta has also support for Atheros AR9285 but I guess it is different card.
Check out this Ebay page where you can see some notebooks shipped with this card. My HDX is on the list

So what do you think. Am right about my assumption?

Could you please make sure you have everything same with Mammoth. Which mac model do they use? If you use a wrong mac model and OSx starts to look for a specific hardware for that model, you may have serious problems.

Unfortunately I couldn't find a solution yet. But in the meantime I have fixed two problems.

First, from time to time, I had the following error message on Console:

Quote

Not loading kext com.apple.driver.ACPI_SMC_PlatformPlugin - not found and kextd not available in early boot.

After fixing SBUS device, I don't see this message anymore. It's been almost four days and it is gone I think. Here is the hack I applied.
Edit: I got the same error. So it is not related to SMBUS. It is may be because of the fact that I use a legacy ACPI plugin from Extra folder.

Secondly, I had this error message:

Quote

FireWire runtime power conservation disabled. (2)

I fixed it by applying a firewire hack but since I don't have a firewire device I am not sure if it will have any drawback. Here is the hack I used.

I'll update HDX topic soon.

Hi folks!

I have a recently purchased HP dv6-2155ee (very similar to Yehia Amer's) and I'm willing to test and experiment anything necessary to achieve as vanilla a build as possible. I've taken a look at Mammoth's guides, but seeing what I've read from these past few pages, there's been some interesting new developments of interest, especially pertaining to audio.

I've quite a bit of experience with setting OSX up, I'm actually typing from Snow Leopard on my desktop machine right now, which is a 100% vanilla build with no system files modified, just the regular stuff in E/E.

But alas, this HP laptop is another issue altogether. I took a look through Mammoth's guides and I intend to follow them (which some required deviations which I will make very clear when I post my results)

As far as I'm concerned, there are two main issues that prevent me from using OSX as a primary system on my laptop:

• The insyde BIOS issue: Exactly what's the difference between the Kokomal kernel and the regular vanilla kernel? Is it just the two line lapic fix? Why does it require removing some .kexts, and how does this affect the popping sound issue?
  I am considering just using the meklort bootloader which patches the vanilla kernel on the fly.
  
• Wireless. I have the same Broadcom card as Yehia Amer, and am wondering if as if yet there is a fix for getting it to work. If I'm not mistaken, the Broadcom chipset is supported by Apple, but is not accessible because it does not power-on during boot up, so if the wireless card is off, it can't recognise it. The wireless switch doesn't do anything. How can this be fixed?
  Is it possible to use the pin 20 method here? Removing the card from the laptop, covering pin 20 with tape or simply cutting pin 20 off, then plugging it back in so it's permanently on and therefore recognised by OSX?

Oh, and there's a fix for time-zone mismatches when you boot up to windoze 7. OSX synchronises and sets the time everytime it boots, and sets the BIOS clock to a UTC standard. win7 has no idea it's operating under UTC time, so it needs to be told that it is with a very simple registry fix:
Open Registry Editor (start>run>regedit.exe) and go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation
Then click Edit>New>DWORD Value, and name it RealTimeIsUniversal, and then give it a value of 1. Close Registry Editor, reboot into OSX, then reboot into win7, and enjoy properly synced time on both systems

Thanks guys!

EDIT: added to clarify that I meant that my laptop has an internal Broadcom wireless card, 43224AG, but if I'm correct, OSX doesn't recognise it because it simply isn't powered on during boot. I think the IOPCIFamily kext may fix this.
My laptop is an HP dv6-2155ee, exactly the same as Yehia Amer's dv6-2170ee except I have an i5 540M instead of an i7.

Model: HP Pavilion dv6-2155ee
CPU: Intel® Core™ i5-540M Processor (3M Cache, 2.53 GHz)
RAM: 4GB DDR3
GFX card: GeForce GT 230M, 1GB PCI-E
Sound: IDT 92HD75B3 @ Intel Ibex Peak PCH - High Definition Audio Controller [111D-7603]

Yes, I did the same thing. I visit the link you gave earlier. Open the BIOS image with EzH20 & then access the EzH20 in memory using HEX editor. I use HxD because it is free. You should see the list before "1.0.4.-.U.n.s.u.p.p.o.r.t.e.d. .w.i.r.e.l.e.s.s. .n.e.t.w.o.r.k. .d.e.v.i.c.e. .d.e.t.e.c.t.e.d" at ASCII pane in HEX editor.

There is a shortcut for all of this by decompressing the BIOS image with Phoenix SLIC Tool. It support Phoenix, Insyde & EFI BIOSes. However, there are hundreds of files after decompressing it. To find the right file would be time consuming. It is possible to remove the white-list check via this method.

UPDATE: The list I post earlier is no use to us. From quick search it is FCC ID. I tried to search for QDS-BRCM1043 & I found out it is actually a bluetooth device.

I'm not sure. Need to check it in BIOS image since the list I post earlier probably a list of supported bluetooth device.

I have AR9285 on my Asus K42JV & it is not working. It is detected as AirPort Extreme & the wireless icon appeared but it can't detect or join any network. I didn't test it with 10.6.5's beta IO80211Family.Kext yet. oSxFr33k's Asus_G51Jx also have AR9285 & it does work. So, be careful with AR9285.

The wireless card at the ebay page is full miniPCIe card.

Next month, I'll be in the UK and have already found a guy on Ebay selling Atheros AR9280 802.11a/b/g/n. The worst case scenario is that it will cost my £30

Hi JBraddock,
thanks for the link/suggestions. They are really detailed and precise, as usual in your posts!
Unfortunately PleaseSleep is an application that force system to sleep after a few minutes/hours (that forces what actually power saving prefpane already does). In my case i would need an application that forces sleep when battery goes down under 10% because it doesn't go to sleep and computer powers off. Does it work for you in HDX18? I mean, when you reach low battery does your hdx18 go to sleep automatically when battery goes down(assumed it is properly configured for sleep/hibernate) ? It happens that i am working and i don't hear any sound message from battery-low warning so i see my computer powering off under my fingers without going to sleep (or hibernate).
I would need a solution for that ...

Thanks!
Mal

LID Sleep: See Valv's LID hack if it works for you.
Force Sleep: Use a third party app. It may work. I am pretty sure I read something about force sleep in this forum and saw a few apps but I couldn't find them. Try this.
Disk Utility: Check if your HDD is seen as internal. Open Disk Utility, click your HDD, look below. It should be Connection Type: Internal
When you log into OSX and, say, you have three partitions, and when you see the desktop, do you see all your partitions mounted and ready or just the OSX partition and then the others follow?
Audio Pops: I don't know the reason of this but I suggest, if Kizwan agrees with me, you don't use SignalProcessing for internal speakers. In my case, it reduces the quality of sound in a very noticeable way.
Battery: Is your battery seen as internal? I had the same problem with HDX before applying Valv's hack. I used to have random KPs while plugging or unplugging the power cable.
Usb & Bluetooth: Check your USB fixes in DSDT. May be there are things to be done. Most HP laptops have these problem and as far as I read these are because of HPET conflicts. Especially, left USB port has always been problematic.

Be careful with SMBIOS.plist. I remember set my mac model MacbookPro5.4 and once I started to use a legacy speed step kext, HDX went crazy. Soon I realised that it should be MacbookPro5,4. If you have applied any CPU related hacks, popping sound might be related to that. I don't know about which version of Chameleon you are talking about but use this thread and do not use a special version of Chameleon or a kernel until you make sure that all your problems are not related to Chameleon or the kernel.

Wireless. I have the same Broadcom card as Yehia Amer, and am wondering if as if yet there is a fix for getting it to work. If I'm not mistaken, the Broadcom chipset is supported by Apple, but is not accessible because it does not power-on during boot up, so if the wireless card is off, it can't recognise it. The wireless switch doesn't do anything. How can this be fixed?

• Is it possible to use the pin 20 method here? Removing the card from the laptop, covering pin 20 with tape or simply cutting pin 20 off, then plugging it back in so it's permanently on and therefore recognised by OSX?

Use tape to cover pin 20 (both side). I already tested this & it work. It keep the wireless device ON.
