The first thing is the BIOS. I've been testing 5802 and I can't get it to boot into El Capitan with Clover at all. I used 5601 even before modifying it and was able to install Mavericks with Chimera and UniBeast just fine.
So, first get the BIOS 5601.
Disable VT-dThen download Mavericks.
Enable I/OAT in CPU IIO Bridge Configuration
Then use UniBeast with Chimera to install the OS using npci=0x2000 PCIRootUID=1.
Remember that Maxwell GPU's are not supported on Mavericks. So, definitely no 900 series cards and some 700 series cards.
I put the GPU in slot 3 and never had issues.
If you have a problem getting into the installer, you may need cpus=1.
After you have successfully installed the OS, use MultiBeast for Mavericks to install the rest of the kexts. Use EasyBeast, and select ALC 898, 3rd Party SATA, Intel Generic AHCI SATA, ElliottForceLegacyRTC, EvOreBoot, all FakeSMC plugins, NullCPUPowerManagement, USB 3.0 Universal, VoodooTSCSync 8 Core, AppleIntelE1000e v3.1.0, Chimera, PCI Root ID Fix, and either MacPro 5,1 or 6,1.
After all seems well, you can mod the BIOS chip by following the instructions here [video=youtube;fHAlsQvDMN4]https://www.youtube.com/watch?v=fHAlsQvDMN4[/video]
It's not hard but I would recommend having a second BIOS chip ready or you may be able to use the CrashFree BIOS method as outlined in the manual.
Let us know how it goes.
For those wanting to do this install on Clover, you should be ok. I'm still testing some things out to figure out why I have the GPU bugs I do. I'm thinking now, that its more related to my original install. I'll have a busy schedule this week but I will try to do a fresh install and see what happens.
Thank you for posting these instructions. It's a shame they are so far into this thread that they are hard to find. The original post is several years old and most of the posts in this thread are about installing mountain lion.
I am only now starting this build because the price of the Xeon E5-1270 v1 has come down to about $65 making it affordable. However, I would like to start with Mavericks, but know that I can install El Capitan at some point down the line.
Your post is the clearest indication that this MB will accomplish what I want to do.
