Reference Guide

The following steps describe how this works using a Linux boot image:
1. A Target Machine (either bare metal or with boot sector removed) boots.
2. The PXE-enabled NIC broadcasts a DHCP request.
3. A DHCP server receives the request, and then responds to the client, offering the following information:
• An IP address, subnet mask, DNS, etc.
• The address of the TFTP server
• The location of boot files on the TFTP server
4. When the client receives this information, it contacts the TFTP server to get the boot image.
5. The TFTP server sends the boot image (pxelinux.0), and then the client executes it.
6. The Operating System is loaded.
By default, the boot image searches for the pxelinux.cfg directory on the TFTP server for boot configuration files.
UEFI allows PXE-enabled NICs to boot on IPv6 systems. UEFI capable systems also have the option to specify the PXE IP
boot ordering. The VC GUI updates the Ethernet connection configuration of a profile with this setting. The user can decide
the order in which IPv4 and/or IPv6 are used for PXE booting. This setting is configured to the server during the profile
assignment. To support this specification, VC provides a PXE/IP Boot Order drop-down option to specify the PXE/IP boot
ordering:
• Auto (It will be a default PXE IP boot order)
• IPv4Only
• IPv6Only
• IPv4ThenIPv6
• IPv6ThenIPv4.
Conclusion
Our leadership role in the UEFI forum and close association with UEFI development allows us to develop solutions that offer
advanced UEFI functionality. The advanced UEFI functionality we have integrated into the Virtual Connect server profile
provides a highly manageable and easily provisioned system that helps customers to utilize the maximum benefits of UEFI
through Virtual Connect in a Blade System environment.
