[SUCCESS] Installed Monterey 12.6 with OC 8.4 on Asus LGA775 P5G41T-M LX V2 / Xeon L5420 and NVIDIA GT730

[freestart72]

SUCCESSFULLY INSTALLED MONTEREY 12.01 ON OLD MOTHERBOARD ASUS P5G41T-M LX V2 release 2009 LGA775 WITHOUT AHCI with CPU XEON L5420 and GPU NVIDIA G730) with OpenCore 7.6

with OpenCore 7.6 full working: 3D acceleration with Nvidia GT730 patched, audio, all usb, cards reader, mouse and keyboard, cpu throttling, sensors temperature, brightness level with app third parts, lan network.

For installation I have used Opencore 0.7.6. I have used online installation because my motherboard is with boot legacy and my controller sata without ahci so in bios I have changed controller sata in compatible mode. For acceleration graphic I have used Nvidia Kepler Patcher of chris1111 and for audio VoodooHD 2.9.7. For brightness level I have installed app from AppleStore. For cpu throttling I have used FakeSMC3 with his plugins. For making work usb I have used patch of opencore in apci and others. For to use cpu Xeon L5420 I have bought it in net modified for socket LGA775.

yes friend, but you must regenerate new SMBIOS, because I can't share my serial

Were you able to fresh install Monterey from your system directly? If so, can you explain what steps you have taken? Because on my LGA 775 when I try to do a fresh install, it always end up in a boot loop. So far I have learned that you need a working nvram to install Big Sur or Monterey. I am wondering if there is a workaround for that.

You must to do with Opencore online installation
