Hi everyone, I am trying to boot snow leopard onto my computer using a 8 gig usb because i don't own any DL disks. I burn the DMG onto the usb using Tony Macx86 old usb tutorial using my macbook air. When I use iBoot and put the usb into my computer everything works fine and I enter InstallDrive. Many things come up until an error reads "EBIOS read error: Device timeout Block 0x64044 Sectors 0" over and over again. When that error reads, the light on my USB turns off which means some connection is wrong. I have a core i5 processor and an Evga SLI Mobo with 4 gigs of ram and a ATI 4670 graphics card. What should i do?
