Thank so much! I took the plunge & installed this 5521 bios over my 3521 & now all of the advanced menus show up, only thing I had to change was the ATA setting so my HDD would boot up.

Hi my friends. I am writing to you from TURKIYE. I have a laptop Dell 3521 and I want to try hackintosh. But there are some problems about bios. My question is; Can i flash this modded bios to my laptop? İf i flash it that hidden menus will open? I need that menus for hackintosh. If it is safe i will flash it. Waiting your answer. Have a nice day Smile
