Sorry, that is incomplete. You have to mention the default filename 
before the IF statements:

filename "/tftpboot/pxelinux.0";

if substring (option vendor-class-identifier, 0, 3) = "PXE" {
     if substring (hardware, 1, 3) = 00:07:95 {
         filename "/tftpboot/eb-5.4.0-sis900.zpxe";
     }
}

Cheers
