Introduction

The following is a description of a PXE server and of the window used to create a new PXE server. The CapaInstaller PXE server is a generic PXE solution that uses DHCP and Microsoft TFTPD. The PXE server basically works like this:
* A client requests a network boot. The DHCP server responds with the required PXE information

  • The client requests a file download.
  • The TFTP server handles the request and offers the file to the client.
  • The client loads the boot file and displays a menu or simply starts the customized Windows PE.

Description

PXE Service

OSD can use two different types of TFTP services to operate the PXE boot process.
 
CapaInstaller PXE Boot Service also called ciBoot
 
This service requires DHCP servers to supply option 60 to PXE clients, if ciBoot and DHCP services are hosted on the same machine. See link below for details.
 
Microsoft Trival File Transfer Service
 
This service is available in Windows server versions prior to 2008, and requires the DHCP to supply option 66 and 67 to PXE clients.
 
The service is supported for backward compatibility only, and we recommend using CapaInstaller PXE Boot Service instead
