booting 3b2's to single user mode: PLEASE HELP!!

[Joel Reynolds]

I accidently installed win/3b tcp/ip release 2.1 without
prior removal of the files from release 1.1.  Now when I
try to boot the system it crashes due to the conflict created
by the two sets of tcp/ip software.

Does anybody know of a method by which I can boot the machine but
only to single -user mode?  This way I would avoid the problem created
by the conflicting tcp/ip software as it would not be initialized.

Please help if you know of any information.  I am supposed to teach in
this lab tomorrow!

Can someone tell me about a so called 'magic mode'?  Someone mentioned
it to me as a possible solution but they can't remember how it works.

thanks
