TravisRidesBikes Posted July 18, 2011 Share Posted July 18, 2011 im trying to install lion GM on a usb drive using [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] usb method (with dsdt) but i keep getting this same error upon booting. i took a photo of my error. I've checked all my bios options everything seems fine. my specs are Msi cd53 motherboard i5 750 cpu 4gb g.skill ram two sata 250gb drive. ATI radeon 4850 graphics card.

TravisRidesBikes Posted July 18, 2011 Author Share Posted July 18, 2011 BIOS mode AHCI It's in ACHI mode. =[ i think it's a usb problem. When that screen comes up the keyboard or mouse are working during that time. Link to comment Share on other sites More sharing options...
Aju Deeju Posted July 18, 2011 Share Posted July 18, 2011 Try this method and use a HD partition instead of the USB Link to comment Share on other sites More sharing options...
juanerson Posted July 18, 2011 Share Posted July 18, 2011 Also, since appear to be a problem with USB ports (maybe IRQs conflict), could try some attempts by using this three Chameleon flags on darwin prompt to test: USBBusFix=Yes UHCIreset=Yes EHCIacquire=Yes More information about help on special keys, boot arguments, and/or kernel flags for Chameleon 2RC5, courtesy: http://forum.voodooprojects.org/index.php?topic=351.0 http://forge.voodooprojects.org/p/chameleo...oc/BootHelp.txt Note: Is recommended to have a fixed DSDT (PCI, USB, wak, RTC, HPET, TIMR, IPIC, SBUS, etc) for Lion. Good Luck. Link to comment Share on other sites More sharing options...
TravisRidesBikes Posted July 19, 2011 Author Share Posted July 19, 2011 I figured out what it was, i removed my dsdt from the [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] drive and it got me into the installation.
