well story goes.. i got os x 10.10 and 10.11 in main hdd and wanted to boot win10 from spare hdd but wont detect then i read similar case and someone states "make shortcut on desktop to DVD then turn off and plug hdd in and now click on dvd icon, will force it to turn on and shows u files!" so that got me thinking.. if it works that way it must be the dvd eject power control in dsdt _EJT. but im no sure if thats the only issue. i will try to mod dsdt to make it think its second hdd not dvd ejectable and flash to bios. anyone got any input ?
