Don�t run the NBI App, you only need the Files for the Bootloader from it, look inside the Application File (its a Container) just copy them to your Partition.

copy the files from netbookloader.img into the root of the setup partition I created from the retail disk and install as usual.cool.

If this actually works & is stable then that'll be awesome, - I use it for live music with ableton so stability is quite important... plugins are v CPU hungry though so worth a shot.

JuiCe, another DSDT to try.
_{4.10.2010, 4:00, minor changes, try it, HPET irqs, OSI, DTGP and sb.INI fixes inside, it may not boot from first time, keep trying at least 5 times so if it boots then 2 cores will work, still not sure why this boot-bug appears}

OK. Frist of all HUUUUGE thanks to XPbIM3 for making it possible for me to run nx7300 with t7200 with both cores without the infamous black screen! I've been testing his dsdt for some time now and it all it seems that it all boils down to this:

CODE

Method (\_SB._INI, 0, NotSerialized)
    {
        \C008 ()
        C01B ()
    }

and changing it to:

CODE

Method (_SB._INI, 0, NotSerialized)
    {
        \C008 ()
        C01B ()
        ISMI (0x46, Zero, Zero, Zero)
    }

I had only minor stability (temperature monitorin disappearing, some apps hanging) problems running his DSDT. I have not yet started to take care of sleep, clamshell PS2 Touchpad.

I will try to try out the netbook installer ASAP but I'm really more interesting in fixing the DSDT permanently and building it into BIOS and flashing it.

To get Your temps low HPET needs 4 interrupts according to my tests. Otherwise the proc stays on 1 ghz (an is still able to run 720p YT videos - 1080p are stuttering, or is it just the graph card not configured/kexted properly?).

What bothers me is that even though nx7300/7400 is prette similiar to other HP laptops which are running SL flawlessly (6720s ASFAIK) we get so meny problems.... Yeasterday I was digging through ACPI table dump of my nx7300 and I have discovered that one of the ssdts lokks like this

CODE

{
    External (INI_, MethodObj)    // 0 Arguments
    External (\_PR_.CPU1, DeviceObj)
    External (\_PR_.CPU0, DeviceObj)

    Scope (\)
    {
        Name (SSDT, Package (0x0C)
        {
            "CPU0IST ",
            0xD77F5876,
            0x0000023D,
            "CPU1IST ",
            0xD77F57AE,
            0x000000C8,
            "CPU0CST ",
            0xD77F5B38,
            0x000004CB,
            "CPU1CST ",
            0xD77F5AB3,
            0x00000085
        })
        Name (CFGD, 0x113369F1)
        Name (\PDC0, 0x80000000)
        Name (\PDC1, 0x80000000)
        Name (\SDTL, 0x00)
    }

    Scope (\_PR.CPU0)
    {
        Method (_INI, 0, NotSerialized)
        {
            INI ()
        }

        Name (HI0, 0x00)
        Name (HC0, 0x00)
        Method (_PDC, 1, NotSerialized)
and so on

And the same SSDT from macbook 2.1 (gma 950 model) and my other i945 notebook do no hahe the "Method (_INI)...." section in it.... Does it ring any bells by You?

I took the boot File, and the /Extra/modules/ Folder from NBI (0.8.5). I don't specify the core count with cpu=x Boot Option.

thankx men, but how did you come about this solution?

wonderful indeed, i mean i am running both for 7 minutes and not a freeze in sight. Normally it take about 3 or 4 minute or even less for it to freeze totally. thankx amigo

Hi!
Could you write step-by-step instruction? I copied all files and directories from NetbookBootLoader.img (boot file and Extra directory) to my USB pendrive with Vanilla install (10.6.3). Is this correct? When I try to boot from it I see only black screen and everything freeze without any message.
I have nx7400 and I can't use both cores too... Please help, there are more nx7400 users with the same problem.

Works!!! I'm running bot cores stable!
You need to do just two things:
- copy boot to /
- copy modules directory to /Extra/
