Legacy CPU Testers Needed

Some of you may know the name AnV from older AMD kernels. He's still active and has written an updated kernel for High Sierra on legacy systems.

The current CPUs should be supported by it but I'd guess more interested in the older ones,

Older Intel Processors:
FAMILY_PENTIUM_4:
All older Intel Pentium 4 processors (Desktop).

FAMILY_PENTIUM_M:
All older mobile Intel Pentium M processors (Laptop).

INTEL_PENRYN:
All older Intel processors with 45-nanometer microarchitecture.

Older AMD Processors:
AMD K8 (Ext.Family 0x0f = 15):
All older AMD K8 processors with 64-bit processor technology (such as Athlon 64, Athlon 64 X2, and Opteron).

AMD K10 (Ext.Family 0x10 = 16; Ext.Family 0x12 = 18):
All AMD K10 processors with 64-bit processor technology (such as AMD Phenom and Athlon X2/X4 series).

Newer AMD Processors:
AMD APU (Ext.Family 0x6 = 6; Ext.Family 0x14 = 20; Ext.Family 0x15 = 21)
AMD APU Athlon 5350 (Ext.Family 0x16 = 22):
All newer AMD Accelerated Processing Units (APUs), including the AMD APU Athlon 5350. These are a combination of
CPU and GPU cores on a single chip for desktops, laptops, and embedded systems.


Newer AMD Ryzen Processors:
AMD Ryzen (0x17 = 23):
All AMD Ryzen processors of the latest generation of AMD desktop processors based on the Zen microarchitecture.

I myself have an old K8 AMD CPU system but it's GPU isn't PCI-E and not supported past Leopard from what I can tell so I can't test this myself. If you've got an older system and are willing to test the kernel either visit InsanelyMac to download and report back to AnV or Spakk, who built the kernel from AnV's source. Or I'll upload to the end of this post and you can report back here.

Thanks in advance :)

You'll need to make an offline USB installer so that the kernel can be replaced. Check the InsanelyMac thread for Spakks instructions on replacing the kernel.

Okay, I understand. I will assemble the Pentium 4’s and Athlon 64 on the work bench, let’s get this party started.

these machines do not support UEFI so I will need to educate myself on legacy booting

Sounds pretty cool to breathe life into old tech :)
Will it not run very slow though? My 2008 first gen unibody was a C2D 2.4GHz/4GB ram/2.5" 5400rpm hdd when it came out, that ran fast even on newer OS', but surely a 800MHz K8 or P4 would be a bit slow? Maybe not a big GHz P4? But the K8 surely?
