Yes and no. We have flash-bootable systems--that is, you can install
your own "payload" in flash--and features related to boot device
selection, e.g., PXE, are no longer available from the minimal BIOS
that initializes the platform and launches your payload.
Instead, you provide whatever boot services are relevant to the
application. It turns out that providing reasonably general PXE client
services can be provided by Busybox and a shell script in about 380
lines. Such capability includes using TCP and a highly scalable web-
server for delivery allowing you to get *well* beyond the scaling limits
of even atftp.
