Update the BIOS before installing Windows 7 on a Dell Optiplex 760

I tried installing Windows 7 Enterprise x64 on a Dell Optiplex 760.  I used the Windows Media.  The installation was so slow that I didn’t let it complete.  I tried a 32bit version and there was no difference.  I did some searching online and found a comment on Microsoft’s site that updating the BIOS should work.

I was using BIOS version A02.  Updating to the latest version (A08) worked.

I then had a problem where the Windows 7 installer couldn’t see the physical hard drives.  I went into the BIOS and changed the SATA mode from its default setting to something which I don’t currently remember and it worked.  Windows detected the disk drives.

I’ve seen talk about installing the drivers and the problem goes away, but that’s not practical in manual pre-installation.
