 Yes, as requested by the prompt "Please remove disk 1, insert disk 2,
 and press return...".

 I tried this on a physical machine and was able to boot successfully
 using the following procedure:
 
    Boot from boot1.fs
 
    At the "Please remove disk 1, insert disk 2, and press return..."
    prompt, do as requested
 
    When the boot prompt appears, immediately press a key to stop
    the countdown
 
    Remove boot2.fs and reinsert boot1.fs (without having been prompted
    to do so)
 
    Type "boot fd0a:netbsd" at the boot prompt
 
    The kernel starts loading.  Halfway through the load, there
    is another "Please remove disk 1, insert disk 2, and press return..."
    prompt; do as requested
 
 This is of course only a workaround; the fact remains that if you
 follow the documented install procedure and the prompts shown during
 the boot process to the letter, the boot fails.
 
 Adding a prompt to reinsert disk 1 before the boot prompt would be a
 possible fix, but not a very good one since it would mean the user
 has to perform a total of four floppy insertions instead of two.
