using boot floppy

[tyche ica net]

background: i have a customer who has forgotten their passwords and havent 
used the machine in a couple of months. because of various other problems, 
grub is NOT co-operating to put the customer into single user mode. i am 
sending a boot floopy for the FC2 system that i sent her. (some piece of 
hardware doesnt want to work for anything above that.) when i installed the 
system, i used the pxe boot and tftp for the initial boot as the internal 
cdrom port doesnt work.

the machine will only boot from an internal cdrom, internal floppy, internal 
hardrive or an external usb floppy.

the plan is: a boot floppy, edit the grub.conf to force the machine into 
single user mode.

what is the command line for the boot floppy?
