I would update that BIOS. I think 0303 is 3 versions old? Everything else should work the same way except for the video card. I have no idea if you need to do anything to get the 8400GS to work, sorry...

Yep, USB SuperSpeed is USB 3.0. System Information.app will still report that a USB 3.0 device you attach there will have speed of up to 480 Mb/sec, but that's just a cosmetic issue. You should get actual USB 3.0 speeds. My USB 3.0 external hard drive for example transfers at around 960 Mb/sec.

That plugin isn't a graphics driver, it's just for monitoring voltage, temperature, etc. I think that's now included by default in the new FakeSMC that Multibeast installs so I left that option off in the updated guide.

I updated the guide for Multibeast 5.2.1 and OS X 10.8.3. It's now much easier with Multibeast 5.2.1 since a lot of the issues in Multibeast 5.0.x have been fixed. I also updated the DSDT I use to one that works with the Mountain Lion AppleHDA.kext. This works with the patched ALC889 AppleHDA...

Yep, I think the only reason Asus claims it can support up to 24GB is because when this board came out the largest single stick of unbuffered DDR3 RAM was 4GB. It supports 6x8GB sticks just fine. The processor in theory can address up to 64GB of RAM, although I don't know if the memory...

Wait, what do you mean it just worked out of the box? How did you install OS X? Did you boot up your system using a live DVD or USB drive? And the OS X installer was able to proceed even though you are not using any kind of bootloader to identify your system as a Mac?

I've noticed that with this driver, on occasion I would get GPU errors which shows up in the syslog as follows: Nov 28 00:58:14 cronus kernel[0]: NVDA(OpenGL): Channel exception! exception type = 0xd = GR: SW Notify Error Nov 28 00:58:14 cronus kernel[0]: IOVendorGLContext::ReportGPURestart...

In case anyone here is interested in having their Asus BIOS boot logo look like the Apple boot screen on real Macs, here's a BIOS boot logo I made with some added text for Asus' BIOS boot options. It has the correct aspect ratio once stretched to 16:9 displays. If anyone's interested I can make...

Dil83 your version of the AHCI_3rdParty_SATA.kext is awesome. Is there a way we can make this version the one installed with Multibeast? I think most people would appreciate having their DVD drives recognized as internal and having DVD player working properly by default.

There are several differences between the P6X58D-E and the P6X58D Premium, so I wouldn't advise using my DSDT for the Premium. I'm using version 0803 of the BIOS for P6X58D-E, and the DSDT I extracted from it appears identical to an earlier one I extracted from my system running version 0701 of...

You should be getting about 120MB/s read/write for a 7200RPM hard disk drive, and even higher for SSDs. 30MB/s is what you would expect for USB 2.0, although many USB 3.0 flash drives are also that slow.

SInce you are running an X58 board with 1600MHz RAM, shouldn't you be running a BCLK of 200MHz anyway, so you'd need only a 20x multiplier to get to 4GHz?

I am also very curious about this. Just what exactly is it about Asus X58 boards in particular that causes kernel panics and/or slow ACPI configuration during boot with any AppleACPIPlatform.kext newer than version 1.5? It's so peculiar...a problem that is specific to only one brand of X58...

Sorry, I haven't experienced anything like that.

Seems like there's a bug in the MultiBeast 5.0.2 installer, when you use it to install the AppleACPIPlatform rollback, it deletes the original but doesn't actually put back the new one. I've modified the instructions and included the AppleACPIPlatform in the attached file so people can manually...

Try booting into verbose mode (it's one of the options in Chimera/Chameleon bootloader), and it'll tell you at exactly which step it is hanging on startup and shutdown. Do you have the CalDigital USB 3.0 drivers installed? It's a know issue that that kext prolongs shutdown time significantly...

I'm wondering the same thing. Though in my case, I'm stuck with the Marvell 88SE9123 SATA controller, which may be the bottleneck.

I used the Asus P6X58D-E motherboard patch and ALC889 patch from olarila.com against a DSDT extracted from my motherboard.

I'm getting 370MB/s sequential read, 230MB/s sequential write in both BlackMagic and AJA, with my Samsung 830 256GB.

Once you have created the boot USB, the install OS X app on the USB drive is very small. That's because UniBeast has extracted the disk image and wrote the files inside the disk image onto the USB drive itself, the disk image is no longer part of the install app.
