# Raspberry Pi5 bootloader EEPROM release notes

## 2024-12-19: Disable fan PWM before shutdown (latest)

* Disable fan PWM before shutdown
  Drive the RP1 fan PWM GPIO high before entering the VPU
  sleep (POWER_OFF_ON_HALT=0) to stop the fan spinning.
* Disable fan PWM GPIO between RP1 init and fan probe
  Drive fan PWM GPIO high during early boot to disable the fan
  until it is probed during the device-tree setup stage.
  This stops the spinning at max rpm during network-install.
* arm_dt: enable_uart defaults to 0 on 2712
  The default value of enable_uart on 2712 is 0, regardless of the
  presence of the debug UART cable, so guarantee that the default is
  always set correctly.

## 2024-12-15: Add net install to boot menu (latest)

* Add net install to boot menu
  Press N (or shift).
