I am having the same problem. I have an Optiplex 745 as well. 4GB RAM, E6600 2.13, ATI HD 4650 (all working in 10.6.8). I am unable to make the transition to mavericks after many tries. I was told I would only need a 2.5.1 IOATAFamily, but the reboot loops suggest more like the chipset (ICH8). Can someone help?

Setup:

 

Optiplex 745 C2D Quad (Q6600) - 10.9.2

BIOS - 2.6.6

SATA0 - SSD - OS

SATA1 - CD/DVD

SATA4 - Storage1

SATA5 - Storage2

 

Successfully installed...all is working, but SATA4 and SATA5 drives will not mount even though SATA4 & SATA5 are enabled in the BIOS (And report themselves appropriately in the BIOS...SATA is also set to Legacy...)

 

When I boot up w/ MyHack's vanilla Extra's folder, all drives show up as expected in Disk Utility

 

When I boot up w/ my install, the SATA4 & SATA5 drives do not mount at all. They don't show up in System Profiler or Disk Utility.

 

I have IOATAFamily.kext loaded in my install as well as an extra injector kext I cant remember the name of ATM. I'll post my full setup as soon as I get home as well as attach my Extra folder, but does anyone have an inkling at what may be causing this? Or what's different about the MyHack boot disk vs. my install?

Could you please post a detailed guide? I have searched high and low and almost no-one posts an actual guide (links broken/depricated, half-descriptions of install process). I am reeling from buying this computer and having MyHack, iFail, and Vanilla installs all fail. The ICH8 is not recognized and all attempts at install end with reboot loop. Please help me understand how you got your 745 to install 10.9? I have 10.6.8 and I can't find the right kexts to load OSX.
