A.7.2 Starting Boot
Boot the client machine and enter BIOS setup to configure “MLNX FlexBoot” to be the first on
the boot device priority list – see Section A.6.
If MLNX FlexBoot/iPXE was selected through BIOS setup, the client will boot from FlexBoot.
The client will display FlexBoot attributes, sense the port protocol – Ethernet or InfiniBand. In
case of an InfiniBand port, the client will also wait for port configuration by the Subnet Manager.
After configuring the IB/ETH port, the client attempts connecting to the DHCP server to obtain
an IP address and the source location of the kernel/OS to boot from.
Next, FlexBoot attempts to boot as directed by the DHCP server.
On dual-port network adapters, the client first attempts to boot from Port 1. If this fails,
it switches to boot from Port 2. Note also that the driver waits up to 90 seconds for
each port to come up.
In case sensing the port protocol fails, the port will be configured as an InfiniBand
port.
