floppy boot hangs

[Dave Whelan]

Hello,
I am a new user trying to install freebsd 7.2 using floppies and ftp. I 
have reached the part where I should start getting an ftp download but 
it couldn't find the server I had selected. Now, the Options Editor 
tells me that "Media Type" is not yet set and I am not able to set it. 
It seems that "Media Type" cannot be set once you have buggered up the 
ftp download.
My question: Is something I can do that will allow me to set the "Media 
Type" from the Options Editor or must I go through the whole boot 
process all over again?
Regards,
Dave.
