I'm want install Xen Server 6.2 though ipxe, I tried different configurations, no luck making to work until now.

I found some may example to boot from pxe using TFTP server, and here is an example:

default xenserver-auto
label xenserver-auto
    kernel mboot.c32
    append xenserver/xen.gz dom0_max_vcpus=1-2 dom0_mem=752M,max:752M com1=115200,8n1 console=com1,vga --- xenserver/vmlinuz xencons=hvc console=hvc0 console=tty0 answerfile=http://[pxehost]/answerfile.xml remotelog=[SYSLOG] install --- xenserver/install.img 

The problem is that ipxe uses different syntax, I could not figure out how to convert this configuration to work on ipxe.

Here is my ipxe file so far:

#!ipxe

echo "XEN Server is booting up"
initrd http://server-ip/pxe/xen/boot/xen.gz
kernel http://server-ip/pxe/xen/boot/pxelinux/mboot.c32
boot

Can any one supply the correct configuration?
