It isn't. You need rarpd, rpc.bootparamd and a NFS server. When you
don't have a floppy you also need rbootd ( every NetBSD has it, I boot
my 345 from a PC sometimes )
To get around rbootd you just need to dd the sys_netboot (or so) image
to a 720kB floppy and let the hp boot from it ( at least this worked for
me, from a 9122 and a 9133 )

Yes and no. NetBSD uses a different partition map than Linux and needs
special bootcode in the first few sectors. Put sys_netboot on the disk,
starting from block 0 and the hp should recognize it as bootable. 

Regarding sys_netboot: last time I did this was 4 years ago, as 1.1 was
brand new. I really don't know how this is handled now, but the image
that gets transferred to the hp when it netboots is just a small LIF
filesystem image you could easily put on a disk. At 1.1 time there was
also a sys_inst image. Put it on any media you could feed to your hp - I
even used a 9144 streamer for this and it worked.
