    Apple A1370 after flash shows no disk

    Hello.
    Have this Apple A1370 that have bad bios. i have trouble with my programmer RT809F and must use A341CH with Asprogrammer. Now laptop start but not see my hard drive.
    I dont work much with apple, is there something that must be done to run os on disk? or i should search for why disc is not recognized. Dump for flash was confirmed working from here

    You must do a NVRAM reset after flashing bios. option command P R is the key combination for this. If. you do not see your drive after this something is wrong with your data.
