Aló.. The Facts My System: Mobo M2A-VM HDMI CPU Athlon 64 X2 Dual Core 6000 HDD Hitachi SATA 2 500GB DVD-RW Samsumg IDE (FAIL) Well, after very test/error times. . I can finally make an installation. Problems: Firewire. You need disable it. If you bios do not show a legend "Firewire" search for "1394" Device, that is the firewire. Your DVD/rw should be a MASTER/Primary (IDE) or First device. Your HDD should to be AHCI ( check for this in BIOS ) In installation Boot try: -v -x -flags cpus=1 HOWEVER, I HAVE A PROBLEM. After succesfully installation.. . the OS do not starting.. I think that my customize options are not right.. may be I need to check the chipsets for install. I have use iDeneb Leopard 10.5 but, I think I will to try Hazard or iPC Greetings!
