I did some quick searches and couldn't find any ISOs for that disc, so I can make an ISO from the disc (I think it's a minimal install cd) and get it to you somehow.
I didn't look hard enough: http://www.google.com/search?hl=en&q=install-x86-minimal-2004.1.iso&btnG=Google+Search
I bet the 2004.1 install disc, which google returns some mirrors for, will work. First result should give you what you need. Hope it helps.
