RAID BIOS Flash Failed: Error 0x6

I've got a PE2850 with a Perc 4e/Di RAID adapter set up in RAID 5.  There is an urgent update to fix the firmware.  When I follow the process, I get a Flash Error 0x6 and the program ends.  Tried a different floppy.  Same problem.

The system was working fine before the flash, and I successfully flashed a different system, but 1) It's listed as urgent, 2) I'm having difficulties installing Windows 7 Pro x64

When installing Windows 7 Pro x64 I am told I have to load drivers.  I was able to get a very old Windows 2003 driver to work, but when it attempts to decompress the files onto the drive (clean install) it gets stuck at 0% and eventually errors out with a media error.  Since my install DVD is new, I'm thinking it's related to the RAID driver.  What driver is optimal for installing Windows 7 Pro x64?

I was able to install Windows 7 Home x32 on a different PE2850 and it's running nicely, but you can't upgrade from x32 to x64.
