Great ! After trying all AppleSMBios kexts i could find to get my real FSB instead of 100 MHz, ilstalling this kext made my problem dissapear. THANK YOU !

[Cillit Bang]

Thanks. Everything working fine except memory frequency showing 0 MHz. How can I fix that?

Ok I'm confused. AppleSMBIOSEFI.kext is the kext we install and this tricks the vanilla SMBIOS into reading your system information correctly using EFI? Is that correct?

My bios does not send the correct information to my system. For example my bios sends to OSX that my FSB is 179mhz x 4 = 716mhz so I have to use the -g flag to force my system to 200mhz and thus I get my 800mhz in OSX even though it shows 716mhz.

Could this AppleSMBIOSEFI.kext correct that? I am guessing not. Currently I am using a SUPERHAI SMBIOS and it pulls my FSB as 716mhz because in his SMBIOS he pulls the information from a special string which I would bet is the same thing used in this AppleSMBIOSEFI.kext.

Please correct me if I'm wrong or explain how this one works differently?

1. use the Finder and copy it in the folder /System/Library/Extensions
2. open terminal and type

sudo chmod -R 755 /System/Library/Extensions/AppleSMBIOS.kext

then type

sudo chown -R 0:0 /System/Library/Extensions/AppleSMBIOS.kext

Reboot.

Argh...

i mean where it was the kext..i found it inside the package.

thnx

it does not show the right bus speed. 760MHz instead of 800MHz

is it just comsetic or the real speed?

I also have 720Mhz Hus Speed instead of 800

Hi mrroboto and macgirl,

You can give AppleSMBIOSEFI_b2 a try.

Hi Cillit Bang,

You can change the memory speed. Just boot with "memorySpeed=n" (n is the speed number you want)
You can change the memory type. Just boot with "memoryType=n" (n is the type number you want, 18 is DDR, 19 is DDR2)

Example:
memoryType=19 memorySpeed=533

Hi 00Diabolic,

I think it has something to do with BIOS, ACPI table, or EFI table.  AppleSMBIOS just read values from them.  If the source is wrong, the outcome is wrong, too.

The difference will be that you don't have to replace AppleSMBIOS whenever it is being updated unless the stucture in AppleSMBIOS changes a lot.

So i must use it with original AppleSMBIOS.kext and I MUSTS NOT REPLACE IT OR RENAME IT AS AppleSMBIOS.kext but live as it....


lemme try...

[rals2007]

Chun-Nan:

Any chance of fixing it on Tiger?

It doesnt work.

Loaded the original AppleSMBIOS of 10.4.11 with E.F.I. installed

[Cillit Bang]

Thanks. Now I got it working. But I wanna add it to my Boot.plist. Do I have to type in there any key or can I just put in the string?

EDIT: Any chance to get a real Serial Number shown in "Hardware" instead of "System Serial Number"?

From your rig description i guess your opteron is overclocked? If your RAM divider isn´t 1:1 (result: 800MHz) it could be the correct speed your RAM is currently working at ...

Hi Chun-Nan,

Great work so far.
This is what it does to my hack.
I like to change the model description and serial number as well.
Thanks for your efforts.

What I also noticed is that there is a double space between "2GB 800 MHz_ _DDR2 SDRAM". I know I'm never satisfied but I hope you can fix that.

Yes my Opteron is overclocked but I am not using AppleSMBIOSEFI on my AMD rig, just in my Dell Laptop, on Windows TAT and CPUZ reports 800Mhz (on the Dell of course).

You put the values in the Kernel Flags key section if this is what you mean. Thanks Chan-Nan I have to check my notes/.kext's installed but I do believe I am running totally vanilla install except for the EFI strings needed now.

	 <key>Kernel</key>
	 <string>mach_kernel</string>
	 <key>Kernel Flags</key>
	 <string>-v memoryType=19 memorySpeed=700</string>
	 <key>Timeout</key>
	 <string>5</string>

It Works!
Thanx

what about photoshop or other apps since we not using macdotnub's AppleSMBIOS-27??

[ontoid]

Wokrks ! Thank U
And it does pick up values settedup by DMICFG
like: machine_model or serial number

CS3 works

Works well also here on my Inspiron 9400, Cpu, Ram, speeds and serial number are correctly displayed. Just on thing, the laptop is recognized as a Mac Pro.
Good Job!
