Default browser change for ecc 6.0 ehp 4 / NW7.01

Hi All I was investigated a little and found out that

to change default browser in NW7.3 you should change some application parameters described in

http://help.sap.com/saphelp_nw73ehp1/helpdata/en/73/142b2a79fb4884a4b4e87fa88f4115/frameset.htm

but for 7.01 there no such things.

Does anybody know how to do change of default browser for soamanager for example in NW7.01

( or to force NW701 to use system default ). I do not find in 701 such parameters like described above nor

such BADIs .
