Debug Nios 2 on external PINOUT

Hi.

Question:

1) It is possible debug Nios 2 on different Jtag chain ?. If somebody know how implement Nios 2 and debug on external Pinout please write me .

Now i have main jtag chain with 3 device. I need reconfigure jtag chain :

a) main chain only developing board device .

http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/cool.gif debug chain only Nios 2.

2) How can i change location for Nios 2 Jtag ?

When i use Xilinx core generator it was possible create switching jtag chain. I try do it with Quartus 5, but isn&#39;t easy.

Please help me if any body know how do it.
