how do you upgrade the PERC6/i firmware?

I have a PE2900 with a PERC6/i.  Went to support.dell.com, put in the 
service tag of the system 38JZCH1.  The PERC6/i firmware download link is:

http://support.dell.com/support/topics/global.aspx/support/downloads/en/downloads_splash?c=ca&cs=rc1077931&l=en&s=gen&~mode=popup&file=279213

So I run it and it makes a directory with:

C:\Dell\Drivers\R200989>dir
 Volume in drive C has no label.
 Volume Serial Number is 1C3B-BB17

 Directory of C:\Dell\Drivers\R200989

Ok, but that doesn't make a boot floppy, and is too large to fit on a 
floppy anyway.  So, I went to bootdisk.com to make a bootdisk, and then 
realized my PE2900 doesn't have a floppy drive.  So what are my 
options?  Make a DOS boot floppy, make an image of the boot floppy with 
dd, and then burn that image to a CD and boot from the CD?  and then 
burn a CD with the files above and run update.bat?
