Hi to all

I hope that this is appropriate place for my request.

I have Dell xps 730 (nvidia chipset) that is missing one option in bios. I can not enable or disable setting for AHCI. It is simply excluded. I have tried to edit bios using various tools but was unable to even open it. According to bios is is Phoenix Award bios but neither tool can open it. I have dumped bios using universal bios tool but even that can not be opened. I'm surely missing something but what i can not understand.

Is there someone who can modify bios to include ahci and sata setting (if they exist)? i can provide original exe file with bios update, original bin file that i have used and a dump file.


Thanks in advance

I believe that you are right about chip-set type. I will check tomorrow.

Only hope that I have is small info is that on this pc i have installed Samsung sata ssd and its software (Samsung magician) is reporting ahci as disabled. Not unsupported but disabled. Software might be wrong.

Damn. Oh well as for now this system is working fine,

Thanks for info.

Out of curiosity how the heck do You open this bios for edit? I have tried every type of editor available and non of them can open it

here are both original and dumped file. A06 is original.

On other note: can I flash bios from another n force 790i ultra sli motherboard? According to pictures that i could find on web every motherboard looks same as Dell one. It is probably manufactured by Nvidia and just re branded.

here is bios of HP BlackBird system that uses similar chipsed and might be compatible. This was taken from http://forums.mydigitallife.info/threads...-SLP-Activation)

I was not looking right. that HP system is using 780I chipset

There are different bios files for same chipset. I have checked every model (visually from pictures that are on internet) and they all look same. Minor changes are in cooling solution but every component and every connection is in same place on motherboard. Nvidia is known as company that produces boards and then lets partners slap on name and model.

I will try to flash one of those bios's. If I screw up there is raspberry pi waiting for flashing bios...

just for the record. bios for xps 730 can be substituted with bios for EVGA / XFX / Zotac 790i BIOS. Even HP Blackbird 002-01B Gaming System bios is working on this motherboard. No AHCI but still it is far better than dell bios
