Yeah, no prob.
NOTE: Our PXE server is Linux (*blech) but I assure you the only thing that=
changes is the paths (/etc/dhcpd.conf becomes /usr/local/etc/dhcpd.conf fo=
r example -- the pxelinux.0 image works fine served-up by ISC dhcpd on Free=
BSD).
First part of the recipe:
$ awk '/filename/&&!/^[[:space:]]*(#|$)/{print}' /etc/dhcpd.conf
filename "pxelinux.0";
$ ls -l /tftpboot/pxelinux.0
lrwxrwxrwx 1 root root 15 May 15 2012 /tftpboot/pxelinux.0 -> pxelinux.0-=
3.84
$ file /tftpboot/pxelinux.0-3.84=20
/tftpboot/pxelinux.0-3.84: data
Next part of the recipe=85 The /etc/pxelinux.cfg/default file:
DISPLAY /boot/include/boot.msg
DEFAULT wpuchar_nfs
PROMPT 1
ONTIMEOUT hdd
TIMEOUT 50
TOTALTIMEOUT 6000
LABEL hdd
LOCALBOOT 0x80
LABEL wpuchar_nfs
=85 your nfs boot config =85
Last but not least, =85
$ cat /tftpboot/boot/include/boot.msg
Press ENTER to boot from WPuchar's NFS server (defaulting to HDD boot in 5 =
seconds)...
--=20
