:::caution
- Default TFTP Settings are compatible with most devices.  In case of very slow or failed transfers, check your NIC vendor documentation for supported TFTP transfer Window / Block sizes. Read more about transfer settings here: [Network Boot Profiles](/capainstaller/the-capainstaller-console/os-deployment/how-to-use-osd/network-boot-profiles/)
- Our Recommended settings to the TFTP Demon is   
  Default Window Size 8   
  Default Block Size 1456
- If you are upgrading from an earlier version of CapaInstaller the old ciboot service be shut down automatically and OSDeployment will replace it.
