Nightingale Posted April 11, 2013 Share Posted April 11, 2013 I have just installed iATKOS S3 v2 on old Toshiba L300 (Intel T4300) on USB-attached drive. HDD is attached to two USB 2.0 ports,. Two ports are needed to supply proper voltage to HDD. After reboot I received "EBIOS Red Error". I cannot disable "Legacy USB Support" in BIOS because HDD will not work properly? I have succesfully installed iDeneb 1.4 in VMWare Player 5 on this machine but it is too slow Link to comment https://www.insanelymac.com/forum/topic/287803-legacy-usb-support/ Share on other sites More sharing options...
eep357 Posted April 11, 2013 Share Posted April 11, 2013 I don't know if that's the cause of your problem, but couldn't you just plug the 2nd "power only" cable into another computer, or a iPhone charger, or any USB port that supplies power? 1 Link to comment https://www.insanelymac.com/forum/topic/287803-legacy-usb-support/#findComment-1905756 Share on other sites More sharing options...
Nightingale Posted April 12, 2013 Author Share Posted April 12, 2013 After disabling Legacy USB support I could not boot any system from USB devices. I have tried older and newer USB sticks with Linux and Windows on them Link to comment https://www.insanelymac.com/forum/topic/287803-legacy-usb-support/#findComment-1906161 Share on other sites More sharing options...
