now xbench: ~160 @ dell inspiron 9400

i reinstalled osx 10.4.8 and does not set the kernel flags. System was slow and jumpy. but after wake up from sleep modus everthing worked fine and smooth. anybody else recordnized this?

what is changing by waking up from sleep?

please help to get us run both cores on every start...

Same with my Dell 9400. Short sleep after boot....... 2 Cores are working. OS 10.4.9 (JaS Combo SSE3)
Thanks !!!!!!

Interesting, which kernel are you guys using?

uname -a:
Darwin noname 8.9.1 Darwin Kernel Version 8.9.1: Thu Mar 15 20:55:00 PST 2007; netkas: 792.18.15~1/RELEASE_I386 i386 i386
Installed with Combo Update JaS 10.4.9 SSE3

How on earth have you guys managed to get sleep mode working on 10.4.9? it doesn't work for me and a lot of other guys I know.

Bizarre heh

I'm not really sure.
I played arraound with Paulicats Kernel and sleep worked with 10.4.8.
The I installed the JaS update and the sleep is also working with the new kernel.

Well I'm using the Mar 24 netkas SSE3 HPET kernel with dsmos.kext at the moment and Sleep mode will not activate.
NvidiaEFI also does not work for me with my GeForce 7800 Go, it used to be fine with 10.4.8 though.
Strange... perhaps there is something different with the JaS combo update, because I actually used the official Apple update and then replaced AppleSMBIOS/IONetworking/mach_kernel myself using Macdrive.

I heard the latest JaS 10.4.9 Combo update retains the 10.4.8 Nvidia kexts as default, can someone confirm this for me?

same to me - using jas 10.4.8 SSE intel only install with mifki kernel - sleep works right after first boot
after jas 10.4.9 update sleep works too.

only using applesmbios from paulicat.

but we need to figure out what happend on wake up so we can use both cores permanently.

I totally agree.

If this wake state is doing something to fix dual core then we desperately need to know what it is.

Yeah, thats really strange. What does a sleep change, so that both cores are working ???
Perhaps the Kernel Gurus can help ....

Well, for experimentation I replaced my 10.4.9 Nvidia kexts with the one from 10.4.8 and it 'almost' managed to sleep, but not quite.
It just hangs with a black screen when I close the laptop lid, which is the same thing Titan.kext does when I force sleep via the power button with the 10.4.9 Nvidia kexts.
I'm gathering JaS' 10.4.9 Combo update does not mess with the Nvidia kexts and leaves the 10.4.8 versions there, but clearly there is something else involved which is preventing me from fully sleeping.
Those of whom have JaS' 10.4.9 Combo installed, do you see Rotation enabled in the System Profile? is your GeForce.kext version 1.4.52.6 (8.7.5f3)?

Regards,

Pawel.

i cant get my inspiron 6400 to wake after sleep. im running 10.4.8 and have no idea which kernel (how do i find that out?). can any1 help? if i can get both cores going i will be a very happy man!

@devilhood
My Geforce.kext is 1.4.40. Date: 4.1.06
Do you mean with rotation the fast change of users in logon options ? (I have a german MacOS)
If so it is disabled.
@fruitylooper
uname -a in Console.

Ok, cool.

That confirms for me that the JaS 10.4.9 update uses only 10.4.8 Nvidia kexts.
When I said rotation, I meant the rotation of your display. This is a new feature of the 10.4.9 kexts, allowing you to change the rotation in display preferences.

I wonder what else it keeps.

Stephen: What exactly did you install? What DVD release, and how did you upgrade to 10.4.9? This information will help us find out how to get sleep working properly, and dual core =)

edit: forget me, my brain isn't fully working today.. I saw your post above heh.

Prasys told me that the dual-core stutter bug exists because of the 2nd core going to sleep.
Putting the laptop in sleep mode and waking it properly re-initializes the cores so they work simultaniously.
There could be a solution by using a good ole' soldering iron, but I very much doubt a software solution exists unless one is willing to crack the Dell BIOS.

To make this clear, this issue unfortunately cannot be solved in the kernel

But this very unlogical. kernel initializes cores wrong on boot and corectly after wake up. so it's same kernel doing that =)
it's not a real bug but i think it can be solved by the kernel.

I agree. If others can reproduce the above (getting dual-core working after waking up), there must be ways to "simulate" such an event by means of software and without touching the BIOS.

I am also on an Inspiron E1505/6400 with 10.4.9 (latest netkas), but haven't yet managed to wake it up after activating standby.

After boot the cursor is in the upper left corner of the screen (just over the apple), so that it is no problem to activate sleepmode with the arrow keys (mouse is not working).
If you don't go to sleepmode, a black screen is appearing after about 30sec.

A automatic sleep after boot may be possible (perhaps there is something like /proc/acpi/sleep in linux)
A little startup skript may do the job (sorry I know only some linux, I'm not a Mac crack)
But you still will have to push the button for wakeup.
In linux a solution over RTC for auto wakeup is possible , but in MacOS ?

I hope we will find a more simple solution.

I think Titan is loaded twice at startup (only dual core boot), perhaps this is causing some problems too.

The kernel isn't actually doing anything wrong. It is purely BIOS related, with the way in which Power Management (S3) has been set.
Waking from sleep re-initializes both cores simultaniously, stopping this whole 2nd core going to sleep problem.
Dell are pretty strict with their settings and lock all functionality of their BIOS the moment a Service Tag number is entered in.

You cannot fix something like this with software, unless you can script a sleep/wake state during the boot procedure, though I'm unsure how viable that would be.
The best possible route is to try and reverse engineer the BIOS itself, because then we would also be open to the possibility of enabling AHCI too.
We'd essentially have a Macbook Pro clone if that was possible

That's exactly what I meant. It might not be as elegant as hacking the BIOS, but IMHO more realistic to achieve.



Ok, anybody volunteering to flash such a modified BIOS?

Heheh, the idea of making my warranty void by volunteering for hacked BIOS testing does indeed sound like a risky one

Ah, but that's what warranties are for

Yeah, that and Dell tech support will pretty much believe anything you tell 'em

thanks everyone for your efforts.
after reading this thread, i reinstalled my system again as per the following order:
1. JAS 10.4.8 DVD
2. JAS 10.4.9 combo
3. Titan.kext
4. IOnetwork from 10.4.6
5. Speedstep.mpkg downloaded from this forum
6. AppleHDAPatcher_v1.15
Then i tried the sleep and wake up, which both succeeded.
Then i enabled both cores in the bios, and proved that after sleep and wakeup, the system went smoothly with both cores enabled.
However, when the second time i rebooted the system with both cores enabled, the system directly went into "four language page" requiring for restart. This repeated for 3 times, after which i gave up the duo core attempt and disabled one core in the bios.
Unfortunately, i was no longer able to mount dmg files again. (i believe it has something to do with the speedstep.mpkg, because when i reinstalled the sytem again without it, everying was ok)
in addition, there is another thing. about the applehdapatcher. I don't know whether you have a stuttering of sound at the very beginning. but whenever i play music, the first 2-3 seconds suffer a stuter. but it will disappear later on. Interestingly, during the experience with the speedstep.mkpg installed (which casued unable to mount dmg files) the sound was perfect.

above is my experience this afternoon.

meanwhile, i am wondering which is more difficult, studying the possibility of rewriting a bios or trying to hack the kernal? lol

sj, just let the kernel guru's do their job, we have the best guys for the job and a new release is coming out very soon

I've only ever experienced stuttering sound on very few occasions when the FSB isn't correctly detected by the kernel at start, but after using the new Apr 1st SSE2 kernel with built-in dsmos, the stuttering went away.
If you decide to use that kernel, you will need to delete AppleIntelCPUManagement.kext otherwise the system wont boot.
Don't worry about it being SSE2, because it will skip any SSE3 emulation after it detects that the proccy is capable.

Edit: Paulicat's Speedstep mpkg is a BETA, but it shouldn't be breaking DMG mounting support. If you decide to use it on 10.4.9 you need to make sure that you are using the 10.4.8 system.kext and kernel.framework.

Did you XBench your Dell when the system was supposedly working "smoothly with both cores enabled"?

thanks dev,

i'll wait for the new kernel and hopefully we can find some solution for the dell bios.





not yet, 'cause i was installing a chinese-input tool which requires a restart, and after that, i was no longer able to start the system.

I need someone to test merom stuff on another irc network

netkas.

Dell related or would any Merom qualify for that?

He doesn't want Dell related merom users, he was mistaken by the thread title and thought it applied to all people that had issues with dual-core.

Well, fixing for *all* dual-core users would be even better. Just don't forget Yonah!

CD and C2D works fine generally, it's just us Dell users that have been shafted because of a POS BIOS.

I have quite a few P4/CD/C2D(i875, i945 and i975) desktop and non-dell systems set-up and running Hackintoshes perfectly

I also have a T7200 and have had both cores running for sometime (little posted here Post 1 , here Post 2 and here Post 3)... How does this run with the flag not being set (platform=acpi)?? I will have to try this..

Read the thread, its a Dell issue.

There is also a strange thing happened to me.
After enbaling both cores on my DELL9400, once a while, there will be an interuption during the start up. Sometimes before the APPLE boot screen appears, and some times in the middle of it. the boot screen will disappear and there is only a line of words on the top of the screen --- "localhost:root#".
After i typed in "reboot" for 3 times, the system just came back.

Originally I thought it had something to do with the speedstep patcher. Now it seems to be also related with the duo core problem.

By the way, I am currently using the IONetwork.kext from 10.4.3 and 10.4.6, sometimes, with the network status showing that i am connected to internet via builtin ethernet, I am not able to get access to the internet. I don't know this is related with OSX or the Parellel Desktop I installed. Will try to figure out somehow.

good night guys.

Something stranger.

After enabling both cores, the earphone seems stopped working, though i still can have sound from the built in speakers.

I am so wondering what had dell done to the bios to make it such unbelievablly shitty.



how difficult is it for some talents to rewrite the bios...........


looking forward to that day

Just a hint, is semthex aware of these?!

Would be nice, if he take a look on this one.

regards,

I notified Semthex of this issue already, he cannot do anything to resolve it.

I told Netkas also, but he called us a bunch of "Dell-heads"

Haha.

LOL

Humm.. Those cores reborn from ashes like phoenix is kinda wierd, isnt?!

Well.. ll try tonight some test im my system.. who knows?!

cya

Got you, HP users are all saying identical issues though. I am assuming it is something with how all these guys do there ACPI... Does the dell bios have the "virtualization mode" in the BIOS like the HP just added (fixed many problems I had in Linux also)??...

Intel Virtualization Technology (VT) isn't related to the problem we are experiencing with Dual-Core unfortunately.

Quoted from Hardware Secrets


So it's only benefitial if you are running VMWare and I assume, Parallels.

Had to reply, my speedstep package has NO problems with mounting dmg's. My package is for 10.4.8 only, and if you try to use it on 10.4.9, you'd better grab the 10.4.8 kernel.framework and system.kext.
If used on 10.4.8, I repeat, it DOES NOT have any issues with disk image mounting.

Now as for the sleep possibly fixing both cores, I can say that waking from sleep fixed a problem on my h.p.
If I didn't send it to sleep then wake it the fan would never come on and it would eventually thermal and shut off.
I eventually found that removing AppleACPIThermal.kext fixed this problem for me without sending it to sleep.

Moral of the story, sending a laptop to sleep and waking initializes the bios/cpu/memory/devices differently then a normal power up. Weird, but true.

Paulicat.

Cheerz for the post Mr. Paulicat

I hadn't tried your speedstep package personally so I'm glad you cleared that up for us.

Do you know what in the system.kext differs from the 10.4.8 to 10.4.9, helping resolve this issue?

I'm anxious to install this speedstep package as it seems to be the answer to some other issues I have been having. I am assuming this will help out many of us (not just Dell users as you seem to have an H.P) as I was thinking for a little while this thread was started for just Dell users - Earlier someone mentioned to me "read the thread, this is for Dell users." Although I stumbled here because of the thread title, not the thread.. If this is only for Dell users, can someone please fix the title!?!

Thanks,
TheVoiceOver

Well, it's essentially for Dell users and anyone else who experiences stuttering with both cores enabled on a CD or C2D proccy.

Finally managed to get sleep (and therefore both cores) working on an Inspiron 9400 with an NVidia GeForce Go 9700 GS.

After much tinkering and many reinstalls, I was able to isolate the video card as the weakest link. Sleep WILL NOT work with Titan or Natit, even if I'm using the 10.4.8 GeForce kexts; using NVidiaEFI 1.0.2 with the 10.4.8 kexts works beautifully, however. Here is the final journey I took to get it working, as far as I can recall:

1) Installed JaS SSE2/SSE3 DVD with Semthem 10.4.8 kernel.
2) Installed mobility.kext (found on this forum) and patched AppleHDA.kext
3) Installed JaS 10.4.9 upgrade combo package
4) Turned SafeSleep off with 'sudo pmset -a hibernatemode 0'
5) Turned off 'Enable disk to sleep when possible' (or whatever) and changed Display Sleep to 'Never' in Energy Settings
6) Installed NVidiaEFI 1.0.2 kext and removed Titan.kext
7) Fixed relevant permissions
8) Reboot and used kernel flags 'cpus=2 fsb=166 fn=1'  (if I do not specify 'fn=x' then I get thrown into single user mode during boot)
9) Use Apple menu to enter sleep mode after OS X is up and running, and the machine goes into S3 state without any issues. Upon wake, both cores are functioning.

'uname -a' confirms I am using the 10.4.9 netkas HPET kernel and I did double-check to make certain that the GeForce/NV40 kexts were still the same version as the 10.4.8 DVD. I also replaced IOPCIFamily.kext and IOPCCardFamily.kext with ones I found in a random thread at one point (attached as 'Extensions.zip', but not the same 'Extensions.zip' available in the 'Useful Files' thread), but as I later re-replaced them with the original versions off the JaS DVD, I do not believe they played an integral role in getting sleep to work.

As for BIOS settings, I'm using the latest A08 and I have NX enabled, Virtualization/Vanderpool enabled, SpeedStep enabled, and both cores enabled (obviously).

Hopefully this will help some of you who are having issues with entering sleep mode and using similar video devices. If not, let me know and I will have a trawl through my Extensions folder to see if there's anything else I messed about with and forgot (it was about the 8th reinstall, so details tend to get a bit mixed up when you're not actually expecting things to work on that particular attempt!)

Best of luck to all! (Now who's going to solve the subwoofer issue so I can have a fully working machine... ? )

Can you enable/disable cores at will?

8.9.1 enabled that on my Fuji.

Thanks for that post, tbcarey. If somebody is able to reproduce this, I'd say it requires an own thread or tutorial.

I am only curious if there are any similar possibilities with GMA950 graphics that many Dell-owners are using. The video-card seems indeed to be the critical factor when trying to get sleep, and maybe dual core working on the Dells.

Did you already have any time to benchmark your system? What kind of improvement do you get with dual core?

Again thanks for your efforts!

Did sleep worked on any of the previous version of OSX86(10.4.5, 10.4.6,.10.4.7 or 10.4.8) with Dell E1705/9400 with GMA950?

"Going to sleep" worked very well here with 10.4.6 and 10.4.8, but the display never wakes up. Same in 10.4.9 now...
