I have an Inspiron 1501 that I've installed 64bit Windows 7 on. It's running beautifully, but I am stuck trying to update the BIOS. Dell only provides the Windows BIOS flash utility and when I try to run that I get the Error Code: 1275 which I've narrowed down to being an issue with 32 vs. 64 bit (I think). I've tried using my USB DOS boot drive but the BIOS utility complains that it will not run in DOS. I'm running the flash utility as an administrator and I've tried all of the compatibility settings.
Does anyone have any suggestions on what I can try to update the BIOS on this machine?
