The X3522 supports UEFI. It is enabled in the delivered factory configuration.
Note: To change whether UEFI is enabled, you
must program new configuration settings into the FPGA flash. See Programming the X3522.
PXE Booting
The X3522 does not support legacy BIOS PXE booting.
PXE over UEFI is supported. This requires a host that uses UEFI for booting and where its UEFI implementation implements PXE. The host can then use the UEFI functions of the X3522 NIC to run PXE over that NIC.
