ASRock Rack EP2C602 Install Guide for Sierra and High Sierra

[JustinKay]

Overwrite the whole CLOVER directory with the attached folder and test.

Still hangs at the same error. I tried using an updated apfs.efi in drivers64UEFI but that didn't help either. Also tried SunKi's Fix for ICH10 with High Sierra.

Hi, thanks for all your hard work!!! I have the Asrock EP2C602-4L/d16 (my asus z9pe just fried so I'm rebuilding)

I'm trying to figure out how to unlock MSR with UEFIPatch. I'm guessing this step is necessary even if I don't need NVME support? So I search "MSR" in UEFITOOL and then patch? Sorry I'm a lil lost

You can use Clover built in MSR unlock.

Just run the program and it will tell you the proper usage.

"Usage: UEFIPatch image_file [patches.txt] [-o output]"

An MSR unlocked copy of the most recent BIOS for your board with NVMe support is attached.

@teamawesome, are you sure what ASRock Rack EP2C602-4L/D16 Support 1.90 UEFI has NVMe support?

@JustinKay, how far did you get!

I am sure I added it. It isn't in there by default, but the BIOS I posted were modified.

Not exactly. Clover's AppleIntelCPUPM will keep the system rom crashing, but it can't unlock the MSR. Modifying the BIOS to truly unlock the MSR is the superior solution.

"Some vendors, like ASUS, restrict the use of MSR register 0xE2 in their power management module to ReadOnly. On Sandy/Ivy Bridge systems the kext AppleIntelCpuPowerManagement will try to write to this register and cause a kernel panic. This patch will eliminate the kext's write operations."

Have not observed any "system rom crashing" and kernel crashing

haha, a typo. "system from crashing"...

Yup. After installing the modified BIOS, I can access your Candy Crush account on any iOS device.
