Hello I know this forum is about the m3n-ht. I have the crosshair II formula which is the difference. If anyone can help this would be awesome. I get Idened 10.5.6 to install, but the second it restarts i go into a restart loop. I get the Apple with spinning wheel for about a sec and system reboots.Darwin boot menu work fine. I have tried different commands and no go. IPC 10.5 PPF will not even load the install for the cd. Thanks for your time on reading.
