Crankyshaft Posted March 23, 2013 Share Posted March 23, 2013 Hi everyone!, Thanks to all who contribute to this forum in any way and to OSX latitude for it's tireless efforts. I have replaced my OEM bios on my D620 with custom bios and would like to revert back to bios A10.I used the recommended flashdrive method. I see the instructions state to use a floppy drive and the recovery file,but no mention of being able to recover with the flashdrive or even how to. Is it possible to just flash back to A10 as I would with anyother biosupdate,or is there a catch. Don't want to brick a perfect machine. Sorry if this has already been discussed but I can't seem to find any reference to it. Regards, Link to comment Share on other sites More sharing options...
geo mac Posted March 23, 2013 Share Posted March 23, 2013 me personaly the easiest way to reflash my bios was to install windows on say a 40g hard drive and just download the bios update from dell and install as an a exe. file ,. now you can only do this as an update as a A14 or higher you cant downgrade a bios to an earlier version ,. I did somewhere a while back write about I used an cd with a windows dos program to create a bios recoverable cd cause I did the same mistake with A17 and cound not downgrade at the time , but its been ages and I forgot the name but it did work like a charm , but honestly the windows .exe is the easiest and best way Link to comment Share on other sites More sharing options...
Crankyshaft Posted March 23, 2013 Author Share Posted March 23, 2013 Thanks Geo, I didn't think of the win option since I've always used either a floppy or flashdrive.I don't have a working external floppy anymore so I am limited at the moment to a flashdrive or your suggestions. I was worried mostly about being able to return it to the A10 bios at all without the custom bios butting heads with it and bricking it. I really see no reason why a cd shouldn't work,I believe that was the way I went to A10 in first place, I must have it somewhere duh!. thanks again!

Administrators Hervé Posted March 23, 2013 Administrators Share Posted March 23, 2013 This has been discussed several times on the forum before. Do a search on say "BIOS recovery" and you'll find various instructions. It's the same process across the D Series (and other models too). Simplest way is the method with a .hdr BIOS file on a USB key. Link to comment Share on other sites More sharing options...
