+Raspberry Pi 5 EEPROM bootloader recovery image
+***********************************************
+
+The Raspberry Pi 5 contains a small EEPROM used to store the bootloader.
+
+This rescue image reverts the bootloader EEPROM to factory default settings.
+
+The easiest method for creating EEPROM rescue images, and formatting SD 
+cards, is to use Raspberry Pi Imager from https://raspberrypi.com/software.
+Raspberry Pi Imager provides a GUI for downloading the latest version of 
+this rescue image and flashing it to a spare SD card.
+
+Alternatively, copy the contents of this zip file to a blank
+FAT formatted SD card. The FAT partition must be < 32 GB.
+
+To update the EEPROM:
+
+1. Power off the Raspberry Pi
+2. Insert the bootloader update SD card
+3. Power on the Raspberry Pi
+4. Wait at least 10 seconds
+
+If successful, the green LED on the Raspberry Pi will blink rapidly forever.
+An unsuccessful update of the EEPROM is indicated by a different blinking 
+pattern corresponding to the specific error.
+
+If an HDMI display is attached, then the screen will display green for
+success or red if a failure occurs.
+
+Once the EEPROM is updated, the SD card can be removed. In order to make
+the entire capacity of the SD card available again, you must then reformat
+the SD card using Raspberry Pi Imager by selecting the 'format card as 
+FAT32' option.
