I haven't got a clue what a K2000 is, but the LTSP or Debian/Edu
does exactly what you say you want.

When a machine boots with a PXE-compliant NIC, it makes a DHCP
request. You have to answer that with an assignment of an IP
address and a special option that tells the address of a TFTP
server.

The PXE client then adopts the IP address and makes a TFTP
request. Have the TFTP server answer with a Debian kernel
configured with an NFS root, and make sure your NFS server will 
make that available to your client.

Modulo a lot of network traffic, bob's your uncle.

Debian/Edu will happily supply you with all the components
above.
