1.I'd check the boot order in the bios setup again,unless you already have.
2.You can make a floppy by booting into dos(use a win9x floppy) and running rawrite :
After dos is up
cd to d:\ dosutils on 1st (install)cd,then type
rawrite. You'll be prompted for an image.Look through the images folder and look for somthing like "boot.img"or"cdrom.img":that's the file you need.Type
\images\boot.img and hit enter.
Rawrite then asks for a destination;just type A:
Also there is a chance that the window app called rawritewin may be on the cd.Look for that to make things easier if you dont do dos
