   BOOT_UART=0   
   WAKE_ON_GPIO=1   
   POWER_OFF_ON_HALT=0   
      
   (Nothing there about BOOT_ORDER, altho my Pi5 (not the computer that showed   
   up with two IPs) does have BOOT_ORDER=0xf461.  But it would appear I'd need   
   a 0x2 in there fairly early for it to try a netboot.)

   Is that in some way that doesn't show up in the output of   
   rpi-eeprom-config?   
      
   Thanks.
