Steven Poon Posted September 1, 2012 Share Posted September 1, 2012 Hi there, i have the e6220 bios a08, 8GB ram, Samsung P830 128GB SSD, i5 2520M, wifi i replace with Dell 1515, i use the myhack to create the USB for mountain lion. after boot up it shows: "EBIOS read error: Controller or Device error Block xxxxxxx Sectors 0" for 5 times than follow with "/" only. If i use the -f it will show the same error as above too. If i use the -v it will show many texts and reboot by itself. Text scroll too fast i cant read anything at all. I try search in google but show me is media fault so i make a few more USB to test but all gives the same error as well. I also try to disable all the unwanted stuff in BIOS in the misc field but still same. If need more info please tell me I will get it or screenshot it. I really want to run mac on this laptop, please kindly help me out here, thanks in advance. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted September 2, 2012 Administrators Share Posted September 2, 2012 try setting your bios to bios mode if in uefi mode. or vise versa. Link to comment Share on other sites More sharing options...
ckleea Posted September 4, 2012 Share Posted September 4, 2012 Something unusual in your machine. Just generic BIOS setting should work. Mine is only 4GB but other hardwares are about the same. No issue in installing ML. Link to comment Share on other sites More sharing options...
