NCD Explora 451 and Solaris 8 x86 Server

Hello, I have bought a NCD Explora 451 (http://www.ncd.com/products/hardware/explora/400ds.html for details) through an auction. I want to connect it to my home server running Solaris 8 x86 and get the Solaris graphical login screen. I read that Explora can do XDMCP and DHCP which is the same way my X-window emulator (running under windows 98) uses to connect to the Solaris box. I would like to khow how to get the same thing with the Explora.
