Modified BIOS to get all cores working

Could you modify a BIOS for me please?

The problem is the system starts running the boot loader and begins loading the disk and then bamn reboots. Even when I do a -v to see the errors it reboots too quickly for me to read the error. I turned off APCI and I did see something about kernel panic. I am completely new to OSX86 but not new to PC's. This is something new for me to try. Any help is appreciated!

Is it possible to get a unsupported Wlan MiniPCI-Express card working?

I bought a Dell 1430 with BCM94321MC.


I dont know if my second core working correctly.


The link to the original BIOS is: ftp://ftp.work.acer-euro.com/notebook/asp...s/BIOS+3.60.zip


I got an ACER Aspire 5633 WLMi.

And I cant change the SATA-controller in the BIOS. Can´t change anything. Lame BIOS :-(



Intel Core2Duo 1.66GHz

2 GB Memory

cpu: intel Pentium Dual Core E2180

video: Leadtek 7300 GT TDH 256 MB DDR2

2BG ram


BIOS(dos version): http://www.asrock.com/mb/download.asp?Mode...T=B&ID=2121

BIOS(windows version):http://www.asrock.com/mb/download.asp?Model=4Core1600Twins-P35&T=B&ID=2122


I get all sorts of kernel panics, It seems it is each time something else(thats why i'm not posting them).

Allso booting with cpus=1 flag doesn't work.

I saw some guys with (almost) my computer specs and they had no problems installing and runing both cores(iAtkos and Leo4all i think).So i would appreciate very much if you could modd this BIOS.


ReSpEcT 4 your work.!

Hi, Kabyl! (I tried to leave a message on the osrom.net board, but without luck)


I would like to request a mod for ASROCK P45TS motherboard.


Here are the links:


http://download.asrock.com/bios/775/P45TS(1.30).zip - DOS BIOS ROM update (latest)

http://download.asrock.com/bios/775/P45TS(1.30)Win.zip - WINDOWS BIOS ROM update (latest)


My CPU is Core 2 Duo T6550, my chipsets are Intel® P45+ ICH10 Chipsets, my graphics card is nVidia GeForce 9400GT 512 Mb.


The problem is that I can’t even load iAtkos install DVD v5i, because it just reboots after it starts loading the install DVD. The issue is the same as I had with my Conroe 1333 motherboard and after applying you patch everything worked just fine. The other problem is that this board has different BIOS settings than in 1333 conroe so it’s hard to find what the new names for VCCM voltage and VDDQ voltage are.

Please mod the following Firmware for me:

MSI P35 Neo-F fw v1.9


I'm using the MSI P35 Neo-F with an Intel E8400 with stepping E0, which means fw v1.8 or above is obsolete. Fw v1.9 is the latest available.

I've seen you have already modded fw v1.7, but it will not work.



Thanks in advance and best regards, lebasti

could you please mod this bios file?



It’s for the ASRock 4Core1600P35-WiFi+


Unfortunately the older version does not work anymore with 10.5.3 and newer kernels.




(I also posted the request on your site, but as there are no other comments I don't know whether you read them)

Greetings Kabyl!

Seems you made a lot of people BIOS happy.


My story:

After a lot and unsuccessfully tries I succeed my OSX86 install with iDeneb v1.3 (10.5.5) on my ASUS V1Sn - AG009E.

I have to say, the only way was to use your "V1Sn301AS" mod. Thank you!


My problem:

To see my both cores in Leopard, I have to boot manually with "cpus=2". Otherwise, I have just one core…

Is there an issue for this?

My Hardware:

- Model: Laptop Asus V1Sn

- CPU: Intel Core Duo T7700 at 2.4GHz

- Chipset: Mobile Intel PM965 Express Chipset +ICH8M

- Graphics: NVIDIA GeForce 9500M GS, External 512MB VRAM



- Original BIOS (from ASUS): http://squarelabel.com/_files/V1Sn302AS.zip


As you see, my BIOS was originally a 302 version so I had to downgrade to your modded version 301 (I don't found a V1Sn302 mod in your list)

Maybe a mod version of this V1Sn302 will work better for me.


In advance, Thank you!

Please correct me if I am wrong, but can't you simply generate a custom /dsdt.aml instead of mocking with your BIOS ROM? Wouldn't this approach be a lot safer?


Also, what exactly and how do you change the BIOS ROM? Is there a step by step manual/guide for this?


Note: I did a: cat /proc/acpi/dsdt > dsdt.aml and iasl -d dsdt.aml on my Ubuntu 8.10 box to generate dsdt.dsl but I can't find that alias you seem to remove!

p.s. I also have acpidump installed, and that dumps this in my terminal window: "Wrong checksum for OEMB

Wrong checksum for OEMB!"

Dear Kabyl,


Can you modifie bios for asus P5KPL-AM


CPU: Intel Core 2 Duo E8500

VGA: GeForce 9800 GT

Link of bios: http://support.asus.com/download/download....SLanguage=en-us

Link 2 of bios: http://www.megaupload.com/?d=48GGLDVH


My problem is that my motherboard FSB is locked at 411 mhz. When i raise FSB over 411 than motherboard doesnt detect my sata disk. Hope you can fix that.


I hope to hear from you soon,

best regards - Christian




P.S: I was reading alot about locked FSB for my motherboard and i came to conclusion it is because of PCI. Here is what i found most interesting on one of the forums:


"Yup, P5KPL doesen't detect sata drives if you reach a higher FSB than 410.

I had this problem too.It's because of the southbridge and PCIEX.

on p5kpl you don;t have the option to raise or lock the pciex to 100... and the board encounters problems... glitches... "


Hope this helps for you.
