StoneTemplePilots Posted April 21, 2013 Share Posted April 21, 2013 Hello, I own an Asrock Fatal1ty Z77 Performance with an Intel Core i7-3770 CPU. The latest UEFI v2.10 has been successfully patched with pmpatcher to enable native powermanagement. Everthings works but not as expected. Still I have questions: * WARNING: IOPlatformPluginUtil : getCPUIDInfo: this is an unknown CPU model 0x3a This means the CPU is unrecognized in combination with the model I adjusted in smbios.plist but as far as I found out there exists an iMac13,2 with similar Ivybridge CPU. You'll find insights at everymac. My smbios.plist holds an entry <key>SMcputype</key> <string>1793</string> which should be - according to ssdtPRGen.sh - the correct CPU type. As soon as I fix my SSDT with ssdtPRGen.sh dropping SSDT.aml from /Extra into Chameleon the system.log shows at boot: kernel[0] X86PlatformPlugin::setRingTable - AICPM failed to load ring table with status 0x0: Get=0, Load=0, Install=0 kernel[0] X86PlatformPlugin::configResourceHandler - Failed to set ring table! What does it mean and what is the "ringtable"? How can it be fixed? I found out on the web there's a lot of confusion about that. Could those error message belong to the patch I did before with AICPMPatch.pl? Anyway I don't understand the several methods explained at ###### belonging to this thread. ------------------------------------------------------------------------------------------------------------------------------------------------ My second question is about dart=0 / disabling VT-d on the Chameleon parameters. With OS X 10.8.3, as we found out, Mac denies to boot due to changes in AppleACPIPlatform.kext which can be skipped with the dart=0 command. As user of Virtualbox I'm not very happy with disabling a feature which has been functional until 10.8.2. Is there a more elegant workaround like fixing this in DSDT? best regards : ) plus thanks in advance Link to comment https://www.insanelymac.com/forum/topic/288051-q-warning-ioplatformpluginutil-getcpuidinfo-this-is-an-unknown-cpu-model-0x3a/ Share on other sites More sharing options...
