>Keywords:
>Date-Required:
>Class: change-request

>Release: FreeBSD 2.2.7-RELEASE i386
>Organization:
JINR
>Environment:
FreeBSD 2.2.7-RELEASE i386
>Description:
This patch intended to provide for the FreeBSD netboot tool the ability
to work over DOS packet drivers. All previous netboot functionality is
preserved, new possibilities isolated in new DOS executable nbpkt.com,
which requires DOS for use of packet driver.
More details in (revised) netboot man page.
>How-To-Repeat:
>Fix:
Apply the following patch to /sys/i386/boot/netboot directory:
cd /sys/i386/boot/netboot; patch < patch.file
