Proper chipset Driver for Aurora R4 prior to upgrading to Windows 10

I think Aurora-R4 is Intel x79 chipset. You can get them directly from Intel.

Intel often releases Chipset Driver installers to support/install many of the latest chipset drivers from one universal installer. That might explain how a different Area51 targeted file updated your machine.

Both in Win-7 and Win-10, Windows-Installer and/or Windows-Update (from online) should also install an appropriate Intel chipset driver.

I decided to use the last posted chipset driver that was specific for the Aurora R4, and "downgraded" to that one from the newer  Area 51 specific one recommended by the Dell Detect, so I think I am OK with all the latest drivers.

However I remain concerned about updating the BIOS. Dell STRONGLY RECOMMENDS updating to latest BIOS prior to upgrading to Windows 10. I might like to use a more advanced NVIDIA video card n the future,  as I am using a GTX 580. That would require updating the BIOS as well.

I am surprised that Dell does not give more specific step by step instructions for updating the BIOS given that potentially thousands of users would need to do this before going to Windows 10.

So can Dell or anyone answer these questions:

1. Please tell me how to create a DOS bootable USB Drive. I see l websites that give one tools that purport to do it, but for something as important as this in terms of ruining motherboard, Dell must have a utility or step by step instructions for doing so. Use Free DOS, MS DOS, what size USB drive, what format type do I use etc. What is the proper utility to create the drive?

2.  Where does one place these BIOS update files on the bootable USB drive? The root directory?

3.Also what precisely does one do or type out once one boots into the DOS environment with this flash drive to execute the file to update the BIOS? I have not used DOS commands.

4. Although one chooses the USB drive as the first in the boot order in the BIOS what about Legacy v s UEFI as type of boot when trying to boot from the USB drive?

5. Finally the BIOS has multiple user chooseable settings, usually set at the factory. What happens to those during the flash? Are they retained? Do I need to copy them all down before upgrading so I can reapply them?

6. Based on users comments it seems safest to apply all of the BIOS updates using Dos, so I would do that, intending to update to A 05 and then A11. But again it would be nice if Dell would tell me if I accomplish this with two updates or have to risk multiple updates which each one in the series from A05 up.

Fortunately my computer is still under warranty.

Thanks

After some research I was able to find the following and post this for others who may have the same questions.

An instruction page and video on how to update BIOS from Dell is here:

http://www.dell.com/support/article/us/en/04/SLN284433/en#How_to_update_USB_flash_drive

Dell does have a utility to create a DOS Bootable Disk found here along with very detailed instructions on how to create the disk which are included in the link above.

One copies the BIOS updates to the root directory.

That said I called Dell support to help me through the process. I was on hold about one minute, and a friendly technician stayed on with me through the process. We performed every available update from A03 to A11 sequentially with no skips, as the Dell support technician indicated not doing them sequentially would lead to no POST problems.

Also of interest was that all of the updates were done by clicking the executable BIOS downloaded file while in Windows 7 environment, and all of the updates worked fine, with automatic reboots in between.

So maybe I was lucky but it all went well. Did not need the DOS bootable disk. But nice to know how to create one if desired for the safest process.
