We are having an issue with the above laptop model where we hear static/popping during playback of audio files. The static and popping that’s heard during audio playback, only starts after a new laptop is imaged, whether deployed by FOG or Macrium. The laptop that was used to create the image from is fine. The current configuration is as follows:

Operating System

• System Memory 16 GB DDR4 SDRAM memory (16 GB + empty slot) (32 GB upgrade available)

@george1421 George, please see the link attached. https://www.dropbox.com/s/6y7ci7g8huegm9p/output.pcap?dl=0

@george1421 I am getting the same result. I am running dnsmasq 2.78

@george1421 Thank you.

everywhere this conf file says <fog_server_IP> I need to edit for my ip Address, correct?

Here is my Itsp.conf file. Thank you so much.

# Sample configuration for dnsmasq to function as a proxyDHCP server,
# enabling LTSP clients to boot when an external, unmodifiable DHCP
# server is present.
# The main dnsmasq configuration is in /etc/dnsmasq.conf;
# the contents of this script are added to the main configuration.
# You may modify the file to suit your needs.

# Don't function as a DNS server:
port=0

# Log lots of extra information about DHCP transactions.
log-dhcp

# Dnsmasq can also function as a TFTP server. You may uninstall
# tftpd-hpa if you like, and uncomment the next line:
# enable-tftp

# Set the root directory for files available via FTP.
tftp-root=/tftpboot

# The boot filename.
#dhcp-boot=pxelinux.0
dhcp-boot=unidionly.kpxe,,10.0.0.100
# rootpath option, for NFS
dhcp-option=17,/images

# kill multicast
dhcp-option=vendor:PXEClient,6,2b

# Disable re-use of the DHCP servername and filename fields as extra
# option space. That's to avoid confusing some old or broken DHCP clients.
dhcp-no-override

# PXE menu.  The first part is the text displayed to the user.  The second is the timeout, in seconds.
pxe-prompt="Press F8 for boot menu", 3

# The known types are x86PC, PC98, IA64_EFI, Alpha, Arc_x86,
# Intel_Lean_Client, IA32_EFI, BC_EFI, Xscale_EFI and X86-64_EFI
# This option is first and will be the default if there is no input from the user.
pxe-service=X86PC, "Boot from network", pxelinux

# A boot service type of 0 is special, and will abort the
# net boot procedure and continue booting from local media.
#pxe-service=X86PC, "Boot from local hard disk", 0

# If an integer boot service type, rather than a basename is given, then the
# PXE client will search for a suitable boot service for that type on the
# network. This search may be done by multicast or broadcast, or direct to a
# server if its IP address is provided.
# pxe-service=x86PC, "Install windows from RIS server", 1

# This range(s) is for the public interface, where dnsmasq functions
# as a proxy DHCP server providing boot information but no IP leases.
# Any ip in the subnet will do, so you may just put your server NIC ip here.
# Since dnsmasq is not providing true DHCP services, you do not want it
# handing out IP addresses.  Just put your servers IP address for the interface
# that is connected to the network on which the FOG clients exist.
# If this setting is incorrect, the dnsmasq may not start, rendering
# your proxyDHCP ineffective.
dhcp-range=10.0.0.100,proxy

# This range(s) is for the private network on 2-NIC servers,
# where dnsmasq functions as a normal DHCP server, providing IP leases.
# dhcp-range=192.168.0.20,192.168.0.250,8h

# For static client IPs, and only for the private subnets,
# you may put entries like this:
# dhcp-host=00:20:e0:3b:13:af,10.160.31.111,client111,infinite

I am using dnsmasq because I am using an old Linksys WRT54G ver.6 router as my DHCP server. It does not support “option 66” which from my understanding is needed for tftp boot image, correct?

I am not really getting a error message. I am getting the following:

DHCP IP: 10.0.0.1 PROXY 10.0.0.100
GATEWAY IP: 10.0.0.1

Auto-select:
Boot from network

BOOT SERVER IP: 10.0.0.100
TFTP
PXE-M0F: Exiting Intel Boot Agent

Then the machine boots into windows…

I am setting up an imaging environment on a standalone network. However, after following the installation instructions my client gets an IP address, however, does not see the TFTP boot image and won’t boot. I am sure it has something to do with dnsmasq, but I am not sure.

Any help would be great.
