Asking issue

[thunfischente]

In the past, I saw Z440 got some problems like bios checksum, does it still there bro?

[BillDH2k]

Not encountered that in my setup, using RTC exclude 80-E1. But I have minimal hardware add-on, so your mileage may vary.

[thunfischente]

How can I use using RTC exclude 80-E1 please Thank you so much for your support!

[BillDH2k]

Using my EFI. The exclude range is specified in the NVRAM's boot-arg.

Your EFI is wonderful bro, it works well on HP Z440, I am using CPU E5-2695v3, and about this Mac shows an Unknown CPU, how can I fix it, please?

[thunfischente]

I fixed it, but I have another question please - about the internal USB, I use a PCIe card for wifi and Bluetooth and use USB jack to connect to the internal USB 2, but it doesn't work (it works on Z420 - the old PC I Hackintosh), I saw you enable internal USB but does it enable, please? Thank you so much for your precious time to help us!

[thunfischente]

It works all now, thank you so much! Wonderful EFI bro!

[thunfischente]

I fixed by this way, do you understand (it is different language to you), if you don't understand I will translate later for you!

HOW TO FIX UNKNOWN CPU Download kext RestrictEvents: https://github.com/acidanthera/RestrictEvents In config.plist > NVRAM > 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102, add value revcpuname, type is String, Value name optional. For example, mine is a 12-Core Intel Core i7. Under PlatformInfo > ProcessorType, set the value to 1537 if the CPU is less than or equal to 6 cores, and from 8 cores or more, set it to 3841. Save config.plist, restart and reset NVRAM and enjoy.

After doing that, "about this Mac" shows the name of the CPU but it shows Xeon W (I use Xeon E5, not W), if you can fix please respond about this!

The z640 wakes up to a black screen after sleep, and the ping fails. Is there a solution?

[thunfischente]

Which card are you using? I meant GPU

[lihaiz]

amd redeon rx560xd

[thunfischente]

normally the black screen just caused by iGPU, but you can try to add this "boot-argv: keepsyms = 1", or you can change the port HDMI to DP
