I really can't tell whether you can or can not do what you are asking. But, when SP2 first came out MS was sending out the update on disk for FREE and no charge for postage. The down load would have buried my dial up! When the disk arrived, the docs even said to share the disk. Check with Gates and Co. to see if they are still sending out freebies!
Considering they dont want you makeign copys of your driver cds..I dont know but then I never read their vague eluas anyway,I have been looking for a SP1 update download so I can keep my SP1 fully updated but so far I cant find much.I will not touch SP2 to many issues to deal with.
