balu28 Posted April 13, 2008 Share Posted April 13, 2008 Hi! When I tried to install the 10.5.2-AMD-EFI-Rev2 version, I just saw this: EBIOS read error: Device time out Block 6721476 Sectors 64 And just wrote it several times, with other Block number. I don't understand it because the 10.5.1 is booting well, but I need the 10.5.2, because I have nforce570 chipset and a sata hdd, so I can't install 10.5.1, because it can't format the disc! Please Help Me! Link to comment https://www.insanelymac.com/forum/topic/99102-installproblem-with-1052-amd-efi-rev2/ Share on other sites More sharing options...
