Answer

The DIP 7000 AIO gen4 device features a port 80 LED that allows you to identify the system status and errors during POST (Power On Self Test).

These POST codes appear at the bottom right of the BIOS screen as a two-digit string that is the same as the two-digit output from the primary I/O port 80.

The A0 indicates the initial state of the SATA device during the system boot process.  It indicates that the SATA device is ready, and the system is operating normally.

After the system boots normally, the POST code will remain at "A0".

For the explanation of other DIP-74 BIOS POST Codes, please refer to the following document: DIP-74 BIOS POST Code.pdf

The POST code may be requested by Bosch Central Technical support in case of troubleshooting.
