You p.c will not take ten years to run the six floppies,it takes mins and will then ask for windows xp cd-rom.
I foind the files are the same as the ones that the cd load anyway.
If you are not installing on a empty drive ,IE after a format, you could just do a full install from your exesting install and it will give the option to download upgrades for the install beforehand.
Prob better with a format and boot p.c from windows xp cd-rom.
I hace did all varients, and seem the same.
