Hi Al,
Why 2 DVD's?
4.0 Gig + .5 Gig = 4.5 Gig.  Most DVD's are 4.4 Gig

Do you need the second DVD for an install?
i386 - no
x86_64 - possibly, but for a standard install, no

Did you download your images from ftp2.scientificlinux.org?


md5sum and sha1sum are ways of verifying packages that you download. 
There are free versions for windows (both xp and vista) but I currently 
do not know where to get them from, possibly someone else on the list 
knows a good place.
How you use them, is you tell these programs what file you want them to 
check.  They then analyze the whole file, and spit out a very long 
string.  That string is unique to that file.  You then compare that 
string to what we have in our md5sum file, or sha1sum file.
If the two strings match, then the file you download is bit for bit, the 
same file as we have up on our server.
If the two strings don't match, then somewhere along the way, something 
didn't get downloaded correctly.
