Hello, I'm a new member here but I've been browsing these forums for quite some time. I absolutely love computers and I have since a being a child.

I wanted to try out the Mac OSx86 system and I finally got a computer capable of doing so. The long story short is that I have an HP Pavilion dv2125nr that refused to boot up despite reinstalling windows, but it happened to be that something in the BIOS was screwed up.

Computer Specs:
1.6 GHz AMD Turion™ 64 X2 Dual-Core Mobile Technology TL-50
2 X 256KB L2 Cache
1024MB DDR2 System Memory (2 Dimm)
2048MB
NVIDIA GeForce Go 6150 (UMA)
up to 128MB (shared)
120GB 5400RPM (SATA) HDD
LightScribe SuperMulti 8X DVD±RW with Double Layer Support
14.1” WXGA High-Definition BrightView Widescreen Display (1280 x 800)
Integrated 10/100BASE-T Ethernet LAN (RJ-45 connector)
802.11b/g WLAN
Altec Lansing
Keyboard is 101-key compatible

2 Quick Launch Buttons (HP Quick Play Menu and DVD buttons)
Synaptics Touchpad


Nevertheless, I bought a new computer with is an Intel-based Sony VAIO NS130E and now I have the HP to play around with now that it will boot up.

Before I bought the actually Mac OS X, I wanted to play around with the installation so I used the Kalyway 10.5.2 DVD Intel_Amd (sse2/sse3) EFI V8. After installing it incorrectly a few times, there was this one past time where I installed it and actually got the OS to run flawlessly aside from sound issues. At the time, I had to go somewhere and didn't want to leave the computer running (and assumed that the sleep command was not going to function properly) so I shut it down. Lo and behold, the thing doesn't want to come back on.

I find it extremely odd that even when you input the exact same boot commands every time, you never get the same result. So I figured that you have to just type in and try random commands. Darwin will not boot the computer properly without me manually hitting "Esc" in the computer's BIOS and selecting the drive I want to boot from. I see videos of people's computers running OS X perfectly with just allowing Darwin x86 to do its thing, but mine is not performing so well.

Usually typing in "sleepkernel rd=disk0s1 -f of -v" will get it to work, but it requires tons of restarts because I still get the "still waiting on root device" thing until it will finally work. Now when it finally boots up, there's no mouse or keyboard recognized and I have no clue why. I cannot plug in a USB mouse or keyboard and input into the machine so it just sits there. I even tried reinstalling it to no avail and the "root device" thing is driving me nuts. Even sometimes when the boot disk is actually recognized, the Darwin codes that display before the OS actually starts just freeze there and stop collecting. How can you input the same thing and computer do two completely different things each time?

And does anyone know about the mouse issue? I think my Intel based VAIO is a better candidate, but with these little bugs working their way around in my HP, I'm just weary about paying a hundred bucks for the Mac OS X and having a ton of problems, but as soon as I can get these worked out, I'll run and get it. The operating system is as intriguing (the last Mac OS system I was good at using was Mac OS 7 on a Power Mac 5200 LC) as I can remember, and I just want to be able to use it properly.


Sorry for the long post but I wanted to explain as much as possible lol.

Thanks

You should only need to select the boot drive in the bios once. When you say it didn't come back on what error did you get?

Re the boot commands, Partition 1 on any GPT disk formatted by Disk Utility will be the 200Mb EFI partition so use disk0s2 instead. Also there's no need to type sleepkernel.

What's your chipset, have you installed the correct driver for your motherboard? Possible solutions for the waiting for root device can be found here.

With your usb issues i would try and toggle Legacy USB support in the bios. Otherwise try a different release, Leo4All and LawlessPPC are better tailored for AMD machines than Kalyway.

Alright, thank you very much for your reply. So you say I should only have to type in the root disk once? Even when I do, there are times when the computer will not recognize the root device. For the SATA and IDE things, I'm assuming that the machine must be taken apart, but my machine is a laptop. The error I get will normally just be a complete automatic restart of the machine, or the machine will simply freeze and hang at a certain spot during the boot. Also, recently when the machine finally manages to boot up, the OS will appear just fine, but there are no input devices such as the mouse, keyboard, etc.

My machine has an AMD Turion 64 X2 processor, and as far as I know, I have been using the Nvidia Nforce drivers. The computer has an NVIDIA GeForce Go 6150 Chipset, but there is no option on the Kalyway disk for that exact chipset.

The funny thing is that the Mac OS X will sometimes recognize the mouse, keyboard and any external hard disks connected to the machine. For instance, when you are in the installer and using the disk utility, everything works. I also managed to get the machine to boot fine just one time with working mouse, keyboard, external HDD, internet, etc. I shut it off because I had to run errands, and it would never boot back up after that. Also, using the verbose boot option, you can see the times where it will recognize the Synaptics Touchpad, and other times where it will ignore it.

For partitioning, I haven't been doing that thus far. I've been simply formatting the hard disk for the Mac OS Extended (Journaled) and just putting the OS on there. As far as your reply, I take to mean that I should be installing Mac OS X on the second partition? I have the installer up and running on the HP and whenever I try to erase the entire internal hard disk (120GB Samsung HM120JI), it still remains as a MS-DOS (FAT) formatted volume. I can however partition the volume so that its Mac OS Extended and Journaled. Is this okay?


And again, thank you for your help.

I installed again, this time I used partition 1 and named it "HP Mac" GUID.

Customization settings were:

SMBIOS --> AppleSMBIOS-27MBmem and
Graphics --> NVinject-256


Results: The computer is recognizing the mouse in every boot, but I'm still getting the "root device error" without typing in the rd=disk0s2. I finally got the computer to get the root disk, and it continues but suddenly stops at.

the computer will not progress from that last line of text. I'm getting frustrated lol

Now it'll get to the point where it says,

*date* localhost mdworker[81]: (Error) Syncinfo: Boot-cache avoidance timed out!
*date* localhost cinfigd[38] InferfaceNamer: timed out waiting for IOKit to quiesce

How long do you wait on the boot?
It can take over 5 minutes to boot, if something is wrong....

So even if it stops on the iokit thing, you can wait on it for a few minutes and see if it goes further.

I normally wait anywhere between 5-15 minutes if it even decides to get that far. Different result each time. I'm now trying different installation customizations for experimentation. This is purely a learning process, so I will do my best and learn this stuff. I guess my current goal at the moment is to get the OS to completely boot up. If I can get this to go on reliably (or somewhat reliably, even if it takes a while each time), then I will begin to get into the system of editing/adding/deleting kexts and drivers.

I have read the sticky threads in these forums about noobs and things posting, and I am doing my best to learn. To all of those who help, thank you. It is very much appreciated.

Edit: I installed the OS with just the basic drivers and no accessory programs. It finally booted up. The sound plays, but is kinda screwy when video is trying to render at the same time (for instance when the greeting screen is coming). The wireless network card is apparently registering in the system info (broadcom unit), but it cannot detect any networks. All USB ports are functioning along with the DVD drive, mouse and keyboard.

This is exactly what happened the last time I finally got it to boot up, but now I am afraid to turn it off because of what happened last time lol.

I may be wrong about this because the issue might have been fixed but as far as I know you can't have any spaces in the boot drive name, "HP Mac".
