+<code>
+$ cd gpxe/bootables/
+$ qemu-img create -f raw testing.img 10M
+</code>
+Here is the code which is working for
+<code>
+$ qemu -net nic -net user -boot n -hda ./testing.img -bootp /pxelinux.0 -tftp /home/myname/for_pxe_knife/
+$ qemu -net nic -net user -fda ./gpxe.dsk -bootp /pxelinux.0 -tftp /home/myname/for_pxe_knife/
+</code>
+for following version of qemu version qemu version 0.10.0
+<code>
+$ qemu
+QEMU PC emulator version 0.10.0, Copyright (c) 2003-2008 Fabrice Bellard
+</code>
+==== Problems ====
+As per me following command should have worked, but It did not worked
+<code>
+$ qemu -bootp tftp://10.0.2.2//pxelinux.0 -tftp /home/myname/for_pxe_knife/ -fda gpxe.dsk
+</code>
+at same time command
+<code>
+$ qemu -bootp /pxelinux.0 -tftp /home/myname/for_pxe_knife/ -fda gpxe.dsk
+</code>
+works.
+Problem faced is,\\
+it successfully downloads the //pxelinux.0// and executes it,
+but it fails when it is downloading pxelinux.cfg/default\\
+It gives an error saying
+<code>
+TFTP prefix: tftp://10.0.2.2//
+Trying to load: pxelinux.cfg/default
+Unable to locate configuration file
+Boot failed: press a key to retry, or wait for reset...
+</code>
+Note : There are some versions of qemu for which network boot option did not worked.
+<code>
+$ qemu -net nic -net user -boot n -hda ./testing.img -bootp /pxelinux.0 -tftp /home/minix-pravin/Etherboot/v2/pxeknife/pxeknife/
+No valid PXE rom found for network device
+</code>
+Above error came for qemu version 0.9.1
+<code>
+$ qemu
+QEMU PC emulator version 0.9.1, Copyright (c) 2003-2008 Fabrice Bellard
+</code>
+But if you provide gpxe.dsk instead of ./testing.img it uses gpxe.dsk stack and boots properly.
+<code>
+$ qemu -net nic -net user -fda ./gpxe.dsk -bootp /pxelinux.0 -tftp /home/minix-pravin/Etherboot/v2/pxeknife/pxeknife/
+</code>
