xen on a 2950 - HELP

[Dirk Allaert]

This has fixed the Xen issue for me (eth0 is still NIC2). You can 
download the utility from 
http://support.dell.com/support/downloads/download.aspx?c=us&l=en&s=gen&releaseid=R125802&SystemID=PWE_1950&os=DOS&osl=en&deviceid=8641&devlib=0&typecnt=2&vercnt=1&formatcnt=1&libid=5&fileid=166797

I did not work for me the first time though. I used the command John 
kindly provided, rebooted, but problem remained. I tried it again, but 
now issued
uxdiag -c 1 -mfw 0
uxdiag -c 2 -mfw 0
I have no idea if the second command is necessary but it works. I can 
now use the default Xen setup (single bridge).

thanks John!
