Ayusete Posted May 30, 2010 Share Posted May 30, 2010 is your ? how about your recovery partition? are you make multiboot with windows? ENVY IOS is still running, yes. I have multi boot with W7, SL and Ubuntu Lucid. My recovery partition is now on external drive. You Cant MBR MULTIBOOT with all those partitions: 1. W7 2. Ubuntu 3. SL 4. System 5. HP TOOLS 6. Recovery So the last 3 partitions are on an external drive now.

Finker Posted June 3, 2010 Share Posted June 3, 2010 so.. please post your guide step by step here...every single step from how to moving your partition.. until kext you used for installation.. not just me read on it, will be every people who have hp envy wan to hackintosh will be reading... I just purchased an Envy 15 and would like a step-by-step account of how you hackintoshed (though I don't much care about the backup recovery bit, as that's fairly simple). I would like to know if you did it with a Mac available to you or not, as I don't own one and do not have access to one. My choice was either the Envy or a Mac, and the Envy was 40% off making it the same price as a 13" MBP.

Finker Posted June 7, 2010 Share Posted June 7, 2010 i can install OS x with snow leopard hazard + chameleon RC5 with "cpus=1 busratio=17"installation complete, but cannot enter OS, always restarting.. I installed it successfully with SL Hazard 10.6.2 and Chameleon RC 3, but unfortunately it won't boot at all. I'm going to try another way ... like only installing 10.6 with the Hazard disc and see what happens. If nothing, I'll try what Ayusate did above (EFI 10.6, etc.). I'll report back any findings (as well as what options I selected under "Customize"). Update: I just tried it again ... didn't work. Here is what the screen shows after the bios: boot0: done boot1: error These were the following options I picked using Hazard 10.6.2 SL: Mac OS X 10.6.2 Update Combo Chemeleon RC3 PC EFI 10.5 VoodooHDA AppleACPIBatteryManager ElliotForceLegacyRTC AdditionalFonts I'm thinking I missed one or two of the correct options and was a little iffy about picking the "ElliotForceLegacyRTC" option. Anyone got any thoughts on how to proceed? I'm thinking of trying the Snow Leopard Retail DVD with Boot132(?) and Chemeleon RC 5 method ... anyone else tried that? I just want to get past that boot error first. Also, I'm running an Envy 15-1067nr: i7-720QM, 6 GB Ram, 1080p, ATI 4830.

stanleyhalim Posted June 8, 2010 Share Posted June 8, 2010 @ bro finker, yup, same with me boot0: done boot1: error i made it with SL Hazard 10.6 too and chameleon RC5, and i think we must try many times with read thet kext function. but short way if bro ayusete post what kext he was made it.. i still try it until now, but not succeed yet.. i have problem with envy ios too, if i make shrink partition and format volume in internal hard drive, IOS not working and f11 function for recovery will not work too. i'm reading in HP forum, i got answer if we want to change OS in our envy, recovery (f11) and IOS will not work. i made it with disk management (windows). i got pop up windows it will change dynamic disk to basic disk. i have same spec HP envy with u bro finker.

Finker Posted June 9, 2010 Share Posted June 9, 2010 i never enter installation mode with retail version... maybe i got wrong step.. but im still trying with hazard kext.. can i add a kext from outside hazard? it's look like a boot thing was wrong or need something... I've been fooling with it all day ... I was able to get one thing to almost work, but it hangs at "system uptime" after I insert the Snow Leopard DVD into the external drive. That EFI was "Empire EFI for Intel Core i7 and Intel X58 Chipset" by aschar (specifically for ATI drivers). All the other disks I used end up getting an EBIOS timeout error. The kinds of commands that I used: cpus=1 busratio=12 (or 17, both seemed to work up until the hang) -v -x -f or -[url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] cpus=1 busratio=12 -v -x -f I got the idea to use busratio=12 because there was a thread I found somewhere that had dvX Quad Editions running hackintosh (here: http://www.insanelymac.com/forum/index.php?showtopic=215033), they are running similiar hardware, so I thought, why not? I will continue to try this method as I think there is promise. As for bringing kexts outside of Hazard, I think we can only do that after we have a successful installation and bootup. Ayusete used the Hazard CD, which the both of us have used and successfully installed. I think the next step though is to worry about the EFI. I was repartitioning on my Ubuntu Live USB and noticed that the Hazard installation left 300 MB partition in front of the OS X partition. That EFI partition, and not the full OS X one, had a boot flag on it ... so the problems we are having are perhaps due to that partition. So obviously, either the Chameleon RC3 (with PC EFI v 10.5) is not going to work for us, or we will have to use it and then install something else after the installation. I'm thinking maybe we need to insert the PC EFI v 10.6 "boot" file into this partition somehow ... or into the /usr/standalone/i386 folder. However, I've been having trouble "seeing" the proper files (boot0, boot1h, etc) there when I move to command line in the OS X terminal on the Hazard CD, but I can see them just fine in Linux. Update: Here is something from the tonymacx86 blog that talks about busratio: http://www.tonymacx86.com/viewtopic.php?f=3&t=642 It appears for the i7-720QM you HAVE to use "busratio=12". Also, I'm looking into that dvx Quad post above and going to see if I can't make that work. Hell, I'll write a custom DSDT if I have to (found a few tutorials that seem fairly "straightforward").

Since my last post, I've made some amazing progress ... I installed SL Hazard, and only checked Update to 10.6.1 and Update to 10.6.2 combo. I popped in the Empire EFI CD for X58 and ATI and then booted the hard disk from there (using: cpus=1 busratio=12 -v). Guess what? It actually booted ... but only to a point. I am now getting an error that says "Still waiting for root device" after running across an error in the VoodooHD kexts on the Empire EFI. I tried booting in single-user mode (-s rd=disk#s#) but it didn't do anything differently. Also, I actually tried booting with [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] + PC EFI 10.6, but it didn't boot at all (regardless of boot flags) ... for that method, I suspect that I would have to insert the proper kexts that Ayusete used. Also, I think that sound might work on the Envy as long as one uses the newest VoodooHD kext (that is, if we can actually get this to fully boot!), I saw some other HPs that had IDT sound drivers that worked with it. And there is good news coming from the Wi-Fi front as well, it appears that Project Camphor, as I understand it, has been porting Intel drivers from BSD and should be done in late June (if he is on-time). Maybe by this time tomorrow, I should have a booted OS X! As for your partitioning troubles stanley, I think you can actually enable/disable the Envy IOS through the BIOS. Honestly, I wiped out my hard disk the instant I got this computer and reinstalled a "vanilla" Windows 7, only taking the drivers I needed from this site: http://forum.notebookreview.com/hp-drivers...y-15-intel.html. I didn't really like the IOS, and I can obtain all the relevant software I need from Google, etc. Plus, I typically dual-boot between Windows and Linux (either Ubuntu or Arch Linux), so I always just start my computers "new". But yes, you can only have 4 primary partitions on your hard disk, if you are using the MBR method, so what you have to do is create 3 primary partitions, and then one Extended partition where you dump the rest of the partitions you need. I usually just use an Ubuntu Live CD, unless I am shrinking the Windows partition, in which case, I use the in-built Windows disk manager.

Finker Posted June 11, 2010 Share Posted June 11, 2010 i liked IOS, if i wanna instant browsing, i always use it.. you can try this partition step. http://www.insanelymac.com/forum/index.php?showtopic=207585 I suppose most people would want to run it ... I'm running an Arch Linux install that gets me, from power button to usable desktop (Fvwm), in 15 seconds, so that's kind of my "Instant OS". That's a pretty good guide and will be helpful for many people (though I have no use for it as I had to learn all of that a few years ago when I tried out Linux for the first time). Something I thought you might find interesting (if you don't know already) is that Windows 7's Disk Management has a feature to convert a partition into a "Dynamic Disk" (you right click "Computer", then hit Manage, then go to "Disk Management", then right click "Disk 0" and finally select "Convert to Dynamic Disk"). Hope that helps you out a little bit. EDIT: By partition, I meant disk. As for this hackintosh thing, I haven't had any success yet, but I also had relatives come over, so I didn't get to devote any time to trying out Empire EFI on a USB + Retail. I would hope that Ayusete would eventually come back and post a step-by-step guide, I know I wouldn't be the only one to have great appreciation for him . But I suspect that running hackintosh isn't going to be much fun until someone makes ATI Mobility Radeon HD cards usable on OS X, because right now ... not many are. But maybe I'm wrong on that. At least the wireless issues should be manageable in a month or two as that Project Camphor is porting drivers from BSD (I'll donate if it actually works!).

Finker Posted June 12, 2010 Share Posted June 12, 2010 Well, I finally got it to work!!! I used the SL Hazard 10.6.1-10.6.2 Disc. Its odd though, I currently have it installed on an external hard disk and not in the internal one. In order to do this, you have to wipe out the hard disk you plan on using, otherwise there will be absolutely be complications (I recommend cloning your partitions and backing them up to another disk using an Ubuntu Live CD/USB or PartitionMagic or whatever partition editor you feel comfortable using). Here is what you must do: 1) Set your boot order to boot from CD first. 2) You MUST boot with boot flags, here is what I used: cpus=1 busratio=12 fsb=133 -v 3) You MUST set the Mac OS X partition to boot from GPT, DO NOT boot from MBR (which is why I recommend installing it to a different hard disk than your Windows installation). 4) Select the following (names may not be exact, but close): - Snow Leopard 10.6.2 Update Combo - Chameleon RC3 + PCEFI 10.5 - VoodooHDA 2.52 - Atheros Fix 10.6.2 - ElliotForceLegacyRTC - SMBIOSResolver Please note: I'm not sure if all of these are required, but I did get it to work ... so hey, that's something at least. Will update if I feel confident to cut that list farther. 5) Now, install it and then reboot into the hard disk that OS X is installed to. If you did it right, the Chameleon screen should pop up. Press TAB and type in: cpus=1 busratio=12 -v 6) If all went well, you will finally be in Mac OS X. As for post-installation ... not much is working right now but that is all fixable. Ethernet: Not working ... I will find the appropriate kext Bluetooth: Working Touchpad and Keyboard: Working, though no side-scrolling or multitouch Graphics: Not working ... will try what I can to make it work, but is unlikely too do so, Expose and Spaces have noticeable frame-rate issues Sound: Not tested yet Wireless: Not working ... but there might just be drivers here in a month or two (July or August) I will post updates and working kexts on this forum, and InsanelyMac, as I find them.

I'm currently trying to use the method provided in the following link to active all eight threads (all four cores), hopefully this works ... http://www.insanelymac.com/forum/index.php?showtopic=215033. In theory, it should work because it fixes some issues that are specific to the HP Insyde BIOS, which the Envy uses too. That, and the dv7t and dv8t quad editions both come, standard, with an i7-720QM processor (and could upgrade to an i7-820QM, like what you have). I should note that you have to upgrade through the Software Update to Snow Leopard 10.6.3 in order to try this method out. May be worth a look if you can't get all your processors running. I'll report back when I've tried this out.
