both cores (T7200) working! Options

[quasar_x]

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.

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

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

Ok, anybody volunteering to flash such a modified BIOS?

[devilhood]

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

[devilhood]

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

[devilhood]

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"?

You have to remember that Paulicat's Speedstep mpkg is a BETA, so I'm not surprised that it isn't working perfectly, especially if it's breaking DMG mounting support.

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.

[OoOoOoO]

I need someone to test merom stuff on another irc network

netkas.

netkas.

Dell related or would any Merom qualify for that?

[devilhood]

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!

[devilhood]

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

[thevoiceover]

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..

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...

Read the thread, its a Dell issue.

[sj1069]

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

[fullOut]

Just a hint, is semthex aware of these?!

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

regards,

[devilhood]

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.

[fullOut]

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

[thevoiceover]

Read the thread, its a Dell issue.

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)??...
