I'm hoping that this info might save someone from avoiding the last two wasted hours that I have just had!!

I've got a Dell E520, and I have just bought a Quad Q6600 to update the old Pentium D processor. But, it was going to need the BIOS updating from V2.2.0 to V2.4.0 to recognise it. That then became the problem. I'm running Win 7-64 bit and that does not have a 64bit facility for flashing the BIOS in Windows, only a 32 bit one in XP. (Damn Microsoft!)

The Dell .exe file It won't work in Safe mode or in a DOS prompt, only way is a bootable DOS disk. But I have no floppy drive, only a DVD. Upshot is you cant make a bootable DOS CD/DVD, at least not that I have found. The answer in the end was to boot up from my Avast Rescue Disk, purchased some time ago just as an emergency backup. It has a dos prompt mode where you can run such a program as a flash BIOS update.

Sorted in 5 minutes! Thank you Avast :-))

So changing the OS selection on the Dell support site to Vista 64 bit didn't give you the 64-bit bios update tool?

Their support site has shoot me in the foot a few times be refreshing, defaulting back to XP, & then giving me the wrong files.

What exactly has Microsoft to do with Dell's BIOS updates?

I know it's not what you wanted, but here's how to make a bootable USB drive. From the GRC Spinrite FAQ:
Hewlett Packard (HP) makes an easy-to-use utility called “HP USB Disk Format Tool”, which includes a "Create a DOS Startup Disk" option. It's freely available from:http://files.extremeoverclocking.com/file.php?f=197 along with the Windows 98/DOS boot files:

if DELL is anything like HP they made the board and its BIOS specifically for that computer and CPU. I ran into the same problem trying to upgrade an HP that had an amd Athlon 3800+. the mobo claimed to be able to handle a dual core and 4X the RAM Not so. HP made two mobo's with the same ID. Both with distintly different BIOSes. needless to say I had to replace the whole PC.
