 **Legacy UART vs. UEFI serial**
 =====================================================================================================================
 
-Starting from OPNsense 22.1 (22.4 for the business edition), support for legacy serial UART0 communication is dropped, 
-since the upgrade to FreeBSD 13-STABLE required a switch to the UEFI serial protocol.
-Prior to this, only legacy serial UART0 was possible. Should you connect your Deciso appliance with a serial line 
-and get limited output / no output from the point of handover to the OS, it is important your BIOS settings are updated 
-to disable legacy UART.
+Starting from OPNsense 22.1 (22.4 for the business edition) and the change to FreeBSD 13-STABLE, support for EFI
+serial has changed, which requires EFI based systems to disable legacy support to prevent confusing the operating system.
+Should you connect your Deciso appliance with a serial line and get limited output / no output from the point of
+handover to the OS, it is important your BIOS settings are updated to disable legacy UART.
 
 While in the BIOS, go to Setup Utility --> AMD CBS --> FCH Common Options --> UART Configuration Options --> UART 0 Legacy Options.
 and make sure this setting is set to **Disabled**.
