My system not reboot!, Because community? Options

[joblo10]

I can't get it to work
Can someone tell me what I'm doing wrong plz

1 - Open mach_kernel (AMD prepatched kernel) for 10.4.4 in HexEdit
2 - Select menu find and GOTO offset 0X8D2BB
3 - Save mach_kernel to a new name like mach_kernel.new to make it writable
4 - Add the following B0 FE E6 64
5 - Save and reboot, at Darwin prompt type mach_kernel.new

When I do this, as soon as the kernel loads my comp just reboots as if I screwed the kernel.

Do I have to to do the hex with the original mach_kernel from 10.4.4 without any patches applied to it?

Perhaps you are not patching in a proper spot or it's a wrong kernel. Otherwise I am not sure whether this patch interferes with other patches (I run Intel SSE3 so dont need that many patches)

[joblo10]

Thanks for replying so fast,

Perhaps you are not patching in a proper spot or it's a wrong kernel.

0x8D2BB puts my cursor at that location : A5 1F 00 HERE EB FE 90 90 90

Do you have the same? No matter I use the original mach_kernel from 10.4.4 or AMD prepatched, I get the same bytes.

Maybe this picture will help you::

At left side - before manipulations, at right side - edited kernel

Thx Omni !

It works very well here, using an AMD64 with 10.4.6 system
It reboots in about 3 seconds!

dont work for me, restart now shuts down the system. lol

[macprodan]

Lol, this is so strange. Shutdown does what Restart used to, Hang. Restart now Shuts Down the system...

[macprodan]

OK, i figured it out. if i add kernel flag Platform=ACPI it work perfect. Shutdowns and Reboots.. Great, this one's going in the OS X list of things to remember.

It works!

I was definatly not doing the good thing, I was adding bytes instead of replacing... works perfect now on my venice A64. I'll remember that an offset location include 4 bytes now

Thanks for the help guys

Great Job with this. Now I can restart without having to press the button manually. Where the hell was this fix hiding?

NPWSKI:

Thanks for the screenshot. This really helped out because I used "Hex Fiend" and could not search for the actual offset, would not find it. I was able to find the line by seeing what you had highlighted in the screenshot, I just searched for that then compared the lines to make sure I had the right one.

Great Work!!!

Omni, just came back from a trip and haven't tried it yet, but damn, THANKS man!!!!! I've been searching hi and lo for this one for a while. I'm going to print it just in case, and keep it in my safe. I didn't remembered who was the author, but did remember seeing it and saying i'll try that later. Thanks, again. Keep up the good work!!!

BTW I knew it was one of the big dogs, HEHE!

woof, woof,

this was on the old win2osx.net forum...mach_kernel 10.4.4 , offset 0x8D2BB, put the following bytes: B0 FE E6 64

woof...

Is it meaning following?

1. musit find the 10.4.4 mach_kernel form 10.4.4?

2. edit and replace the mach_kernel to my OSX whatever your system's version (Like 10.4.3 or others)?

Thanks to omni and many kind guy.

[Sipheren]

works perfect....thx people

[oscarcar]

dont work for me and now not run the system. how I can do to repair mach_kernel??????'
help me please
thx

[muxion]

Excellent thread! When I took out Cel D336 and put in Pent D930, comp doesn't shut off, goes to blink cursor on black screen. I will try this, thanks!

[macgirl]

OMG I missed this one, it works now yay

[axept]

Hi i have an Intel P4 2.8 and i have not applied the amd enabler patch yet,so the Mach_Kernel doesn't have that line,do you think it is safe to apply the amd enabler just to get a matching kernel to edit ?

I saw someone with an P4 saying it worked but i'm affraid of messing it.

thanks

I dont suppose this will help non-working sleep mode? (All that happens is that the mouse pointer disappears)

woof, woof,

this was on the old win2osx.net forum...mach_kernel 10.4.4 , offset 0x8D2BB, put the following bytes: B0 FE E6 64

woof...

so the new line should b like THat offset 0x8D2BBB0 FE E6 64 ??
or like that offset 0xB0 FE E6 64 ??
or something else ??
