Giorgio_multi Posted August 22, 2009 Share Posted August 22, 2009 Updated at 1 April 2009 (USB and LAN section for G31-M S) Premise: This is a guide to install Snow Leopard on this motherboard. I will not answer basic questions as: how flash the bios? and others I public this brief guide to the unfortunate owners of motherboard AsRock G31M-S and G31M-GS (they differ only for the LAN, a RTL81102EL on the G31M-S, which in fact is a 8139clone not supported by Leopard, but I found the solution to make it to work, see the bottom, and a RTL1000 on G31M-GS, supported with the kext present in iDeneb 1.4 and XxX 10.5.6). The sound is an ALC662, which only works with Azalia out (I tried with Taruga patch, but although present in the System Profiler does not go out any sounds), now with voodooHDA.kext works in and out very fine. The USB 2.0 should be in conflict with ICH7 then you must disable the feature from 2.0 BIOS and resolves with a USB 2.0 PCI card that are not controlled by the BIOS and works very well so you can use USB keyboard and mouse (point A of the relevant section of the USB BIOS). Alternatively, using PS2 keyboard and mouse, without additional PCI USB card, by setting the USB section of the BIOS as described in the section B of the relevant section below. The video card inside (GMA3100) is not supported by Leopard so you need an external PCI-E graphic card. Then take iDeneb 1.4 and start the installation of Leopard 10.5.6. You must modified the BIOS 1) Flash the BIOS with the appropriate file: For G31-M S: http://www.insanelymac.com/forum/index.php...st&id=46734 G31MS130.rom.zip For G31M-GS: http://www.insanelymac.com/forum/index.php...st&id=46735G31MGS130.rom.zip BIOS settings: ( only the most important) CPU Configuration: Enhanced Halt State [Disabled] Intel? Virtualization tech. [Enabled] : comparir࠳olo con le CPU che supportano tale tecnologia CPU Thermal Throttling [Enabled] No-Execute Memory Protection [Enabled] Intel? SpeedStep? tech. [Disabled] On-Demand Clock Modulation [Disabled] ACPI Configuration: Suspend To RAM [Auto] Repost Video on STR Resume [Yes] Check Ready Bit [Disabled] Restore on AC/Power Loss [Power Off] Ring-In Power On [Disabled] PCI Devices Power On [Disabled] PS/2 Keyboard Power On [Disabled] RTC Alarm Power On [Disabled] ACPI HPET Table [Enabled] IDE Configuration: ATA/IDE Configuration [Enhanced] USB Configuration: A USB Controller [Enabled] USB 2.0 Support [Disabled] (USB PCI card, USB mouse and keyboard) Legacy USB Support [Enabled] B USB Controller [Enabled] USB 2.0 Support [Enabled] Legacy USB Support [Disabled] (PS2 mouse and keyboard) 2) Start iDeneb 1.4 DVD, initialize the Leopard partition with Mac OSX (Journaled) and in Customize choose: Language: Only your language Additionals Fonts: Yes X11: Si iDeneb Essential System: Yes Patches 10.5.6 Ready: Alternative Essential Patch: ACPI Kext 10.5.6: NO PS2Fix for ACPI kext 10.5.6 (only if you have PS2 mouse and keyboard) AMD Patch: No Audio: AppleAzaliaAudio or nothing if you install later voodooHDA.kext Chipset: ICHx Fixed + JMicronATA Kernel: Nothing or Kernel 9.5.0 Voodoo if you have not a vanilla compatible CPU. Network: RealtekR1000 for G31-M GS nothing for G31-M S Fix: AppleSMBIOS like the frequence of your RAM (seatbelt Fix if you use voodoo kernel) PS2 fix (if you have PS2 mouse and keyboard, point B of USB section) System Utilities: nothing Video: for your videocard Applications: nothing Netbook: nothing 3) Reboot and then: delete AppleDecrypt.kext and install this with kexthelper: AppleDecrypt.kext.zip (if you have choose point A in BIOS section, you must delete AppleHPET.kext too), reboot with -v -f flags and you will have Leopard 10.5.6 on this motherboard. Update 01/04/2009: solution for integrated LAN of G31-M S: delete from /System/Library/Extensions IONetworkingFamily.kext and install this: IONetworkingFamily.kext.ziphttp://www.insanelymac.com/forum/index.php...st&id=47669 with kexthelper and reboot with -v -f Giorgio Link to comment Share on other sites More sharing options...
