Michael,

I am really not using any special software. Under the /tftpboot/solaris:
=================
# ls
S11_112  S11_112_multiboot  S11_112_pxegrub  S11_112_x86.miniroot
# file *
S11_112:              directory
S11_112_multiboot:    ELF 32-bit LSB executable, Intel 80386, version 1 
(SYSV), statically linked, not stripped
S11_112_pxegrub:      data
S11_112_x86.miniroot: sticky gzip compressed data, was "mr1650", from Unix
# cd /tftpboot/solaris/S11_112/platform/i86pc/kernel
# ls
amd64  unix

*S11_112_pxegrub is the boot loader that shipped with Solaris image
===================

Here is the what in the dhcpd.conf:
============================
group {
        use-host-decl-names on;

        # "filename" specifies the pxelinux image on the tftp server 
which will be
        # served to the PXE clients. The configured tftp server on 
xx.xx.xx.xx runs
        # in a "change-root jail" to /tftpboot
        host lab-s1 {
                hardware ethernet xx.xx.xx.xx.xx.xx;
                fixed-address xx.xx.xx.xx;
                filename "pxelinux.0";
        }
        host lab-s2 {  <================== MY SYSTEM loading Solaris
                hardware ethernet xx:xx:xx:xx:xx:xx;
                fixed-address xx.xx.xx.xx;
                filename "solaris/S11_112_pxegrub";
        }
}
===================================

Thanks,
Joyce
