Very Computer

Hi All
i have had to remove our sharepoint install (sbs 2003 Premium) because of a
number of issues, but now i am unable to install again, as i get asked for a
disk with SP1, i do not have this disk, and looking around on the net
slipstreaming the disk is also not an option, is there a way that i can do
this install or where i can get a version of the media with the SP1?
thanks in advanced
steve
