Overview
NVIDIA® PreBoot drivers are a multiprotocol remote boot technology that support remote Boot over InfiniBand (BoIB) and over Ethernet.
Using Virtual Protocol Interconnect (VPI) technologies available in NVIDIA® ConnectX® adapters, PreBoot drivers give IT Managers’ the choice to boot from a remote storage target (iSCSI target) or a LAN target (Ethernet Remote Boot Server) using a single ROM image on ConnectX products.
FlexBoot is based on the open source project iPXE available at http://www.ipxe.org.
PreBoot drivers first initialize the adapter device, senses the port protocol – Ethernet or InfiniBand, and brings up the port. Then it connects to a DHCP server to obtain its assigned IP address and network parameters, and also to obtain the source location of the kernel/OS to boot from. The DHCP server instructs the PreBoot drivers to access the kernel/OS through a TFTP server, an iSCSI target, or some other service.
