Although it is to late:

If your CD is not recognized by your bios or something else,
smartbootmanager (http://sourceforge.net/projects/btmgr/) often comes in
very handy, since it starts from your hd bootsector and then boots your
cdrom from there.

In regard to pxe booting from your additional network card, you can use
rom-o-matic http://rom-o-matic.net/ to generate an etherboot rom image
that you can use to do etherbooting by us9ing the rom image from
diskette or CDrom.
