Hi guys,

Here is the beta AppleSMBIOSEFI I have been working on. It will work with original AppleSMBIOS but will try to fix or add some values that original AppleSMBIOS misses. Therefore, you don't have to worry about AppleSMBIOS being updated.

It is based on original AppleSMBIOS and it only works with EFI system right now. It is for both Tiger and Leopard. In addiation, it should fix "About This Mac" crash problem and wrong "Bus Speed" issue.

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

Again, it is just the beta version and you still need the original AppleSMBIOS with it.

Update: 5/6/2008
1. It will use value of "cpu->externalClock" first. If that value returns 0, it will use value of "FSBFrequency".
2. Add "FSB" flag. You can change the FSB value in case the value is still not correct. Just boot with "FSB=n" (n is the speed number you want) However, it doesn't update the value back to "FSBFrequency" yet.

Update: 7/2/2008
1. based on AppleSMBIOS-28
2. Added "serial-number", "board-id", and "system-type". The default serial-number is "W1234567890".
3. Released AppleSMBIOSEFI from memory after adding the values.
4. It should work both on Tiger and Leopard. (I used Tiger to compile the source code.)

P.S. CoolbookController won't work with AppleSMBIOSEFI_28 because model is set to "MacPro3,1". Try AppleSMBIOSEFI_28Air instead or change the model to the ones supported by CoolbookController.

So if an update comes out where there is a new SMBios, then I don't have to worry as this will rectify any issues?

Why not just use SMBIOSEnabler by Kabyl?

http://osrom.net/

Working good here with vanilla SMBIOS 1.0.14 (from 5.3).
My system can use vanilla SMBIOS without any problems but hardware overview in system profiler gives an error. With SMBIOSEFI system profiler works and using memoryType=19 shows DDR2.

This works better than smbiosenabler.

Really great - that fixes my About this mac crash .
(SystemProfiler runs, didnt crash)

No other ( i tested much!) AppleSMBIOS had fixed that.

This one fixed that crash !

THANKYOU !

Could someone plz send me the original AppleSMBIOS file? I don't have it anymore.

And how do I have to install this?

You can get it from 10.5.3 update from Apple using Pacifist.

Unfortunately, 10.5.3 Update doesn't contain this file.

Try downloading 10.5.3 ComboUpdate instead of 10.5.3 Update (420 Mb)

The AppleSMBIOS.kext is in the guenuine update... and combo.

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

is it just comsetic or the real speed?

sorry for the question, but how i must install it?

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.

nice Chun-Nan ! Worked perfect.

Are you expecting to include a serial number changer too ?

Where do I have to copy the unzipped folder?

EDIT: Guys, plz help! I don't know what to do with the downloaded file.

I also have 720Mhz Hus Speed instead of 800

look in build/developement install kext with kexthelper


Thanks Chun-Nan !

Is there a fix for this yet?

Displayed 100Mhz FSB in system profiller, diagnostic information not found, memory frequency 0 Mhz how fix this. In native SMBIOS and 27th version all displayed much better.

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 !

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?

Argh...

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

thnx

Doesnt work in Tiger 10.4.11 with original AppleSMBIOS and EFI installed
...

Hi mrroboto and macgirl,

You can give AppleSMBIOSEFI_b2 a try.

Chun-Nan



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.

Chun-Nan

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...

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

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"?

@MACGirl:


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 ...

Cheers

Goron

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.

Thanks


EDIT:
Worked



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.

It Works!
Thanx

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

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!

From now on this should be moved as the "proper" way to have a working smbios in distros ...

My XPS is recognized as "Mac" on Model Name and "XPS M1330" on Model Identifier not as "Mac" and "macpro3,1" like others.

I don't know where the name is set, I am using vanilla AppleACPIPlatform.kext also

All work fine, thanx for our work.

Same here!!!

Not sure but ...
I think that in your case Machine model Data entries are from DMI Bios records
and have priority before Model Identifier stored in AppleSMBIOSEFI.kext.

In my case i did edition of those records and wrote there
model: iMac7,1 witch gave me iMac7,1 not MacPro3,1
Same Story is serial number
Click to view attachment

To edit DMI DATA i used small app called DMICFG

Recently figured tiny issue:
(Sometimes) After restart system does not loading monitor calibration profile
and keyboard layout (modifier keys) are reverted to default state.

MacPro3,1 are stored in the kernel, and not in the SMBIOS.

If you are using vanilla kernel, then that's why you see your model identifier as Dell and not Mac Pro.

So, what is the best way to change the Model Name, ID and serial Number?
And how to do it?

I wanna know that, too! Nun-Chan why don't you answer anymore?

If you are running with the ToH kernel, just modify the AppleSMBIOSEFI.cpp

Hi,
I am using the vanilla and ToH on two different riggs.
Do I have to compile AppleSMBIOSEFI.cpp?

If you modified something yes, but open the Project on Xcode and hit the Build button, it will compile the whole thing and create the new kext.
