How to flash UEFI BIOS with iPXE?

[engineer7]

Hello iPXE Forum!

Can iPXE be configured to flash a UEFI BIOS over the network?

My current process:
1. Format a USB drive as FAT32 and copy flash files to USB
2. Boot to UEFI Built in Shell
3. Execute the flash.nsh
4. Reboot system after the UEFI BIOS is flashed
FILES:
afuefi.smc
fdt.smc
flash.nsh
X11SPI8.614

I was able to utilize iPXE sanboot to boot FreeDOS ISOs over a network share to flash legacy BIOS. Now I'm looking for a way to do this to flash UEFI BIOS.

Can you please assist? Is there some way to pull the flash files and flash.nsh script over the network with iPXE and flash the BIOS?
