Carry on. it'll be fine. It just means exactly what it says. You won't be 
doing a standalone floppy boot, will you? (ie boot and run from a floppy)
the following may be already known to you, but you did say it was your first 
time compiling kernels...
A word of advice. Have you checked the top few lines of the kernel Makefile?
If you haven't, do so now and make sure that the 
VERSION = 2
PATCHLEVEL = 4
SUBLEVEL = 20
EXTRAVERSION =
lines do not match precisely any kernel on your system you still wish to 
boot... (the new kernel modules would replace the already existing ones).
I usually tack on something to identify my custom kernel in the EXTRAVERSION 
section.
eg EXTRAVERSION = 9.scsi (or whatever, depending on what I have done)
