How do I build a driver floppy?

[Peter Canning]

In order to boot the installation system (2.2r2), I had to get the source 
code for newer versions of a couple of drivers (SCSI and NIC), build a 
kernel and a rescue disk containing that kernel (using a debian 
installation on an another computer).  As a result, I can successfully 
install the kernel/modules and base system over the network, etc, but when 
I try to boot the base system, it fails because the kernel doesn't have the 
newer versions of the drivers.  I believe that I need to make a driver 
floppy with these drivers, and use it in the "Configure Device Driver 
Modules" step of the installation, but I haven't been able to find any 
documentation on how to create a driver floppy.

Can anybody tell me how to create a driver floppy, or point me to some 
place that describes it?

        thanks
