## 7 segment status and error codes
|
|
|
|
This display next to the mainboard breakout connectors shows an 8-bit hex value indicating
|
|
different stages of the boot process and errors.
|
|
|
|
Errors are usually "stuck values". A healthy boot sequence has these numbers changing to show
|
|
it progresses through the different stages
|
|
|
|
### Healthy boot sequence
|
|
|
|
The following is "transcribed" from a video recording of a healthy boot sequence (from power on
|
|
to game title screen). All values are 8-bit hex values.
|
|
|
|
* `FF`: Initial state shown right after power on
|
|
* `81`: ???
|
|
* `84`: ???
|
|
* `85`: ???
|
|
* `86`: ???
|
|
* `87`: ???
|
|
* `88`: ???
|
|
* `08`: ???
|
|
* `11`: ???
|
|
* `0C`: ???
|
|
* `28`: ???
|
|
* `2E`: ???
|
|
* `38`: ???
|
|
* `09`: ???
|
|
* `69`: ???
|
|
* `49`: ???
|
|
* `4A`: ???
|
|
* `59`: ???
|
|
* `52`: ???
|
|
* `60`: Video output over VGA shows the Andamiro logo on white background, first actual video output
|
|
visible
|
|
* `98`: ???
|
|
* `6A`: ???
|
|
* `00`: ???
|
|
* `01`: ???
|
|
* `C0`: ???
|
|
* `D2`: ???
|
|
* `00`-`99`/`00`: Progress counting upwards from 0 (`00`) to 100 (`00`)
|
|
* `FF`: ???
|
|
* `88`: ???
|
|
* `FF`: ???
|
|
* `88`: ???
|
|
* `A2`: booted from HDD, starting with andamiro MKV bootloader stage and stays also when in-game
|
|
|
|
### Operating system/game booted
|
|
|
|
Once the display shows `A2`, it's also flickering.
|
|
|
|
The bottom segment of the first digit as well as the top left and bottom right segments of the
|
|
second digit are used as HDD, CPU and ??? indicators.
|
|
|
|
### Other codes
|
|
|
|
* `01`: In BIOS menu
|
|
|
|
### Errors
|
|
|
|
#### Stuck at FF right after power on
|
|
|
|
If the BIOS isn't loading, then it is stuck right after power on.
|
|
|
|
This might indicate that something is wrong with the power to the mainboard. Ensure you are using
|
|
the power distribution board of the MKV box and not have a ATX power supply connected directly to
|
|
the mainboard. It powers, but doesn't seem to like that and stays stuck here immediately.
|
|
|
|
#### Stuck at C0
|
|
|
|
Operating system not found.
|
|
|
|
This should also be visible on over VGA output with a message stating this on a connected screen.
|
|
|
|
#### Stuck on B0
|
|
|
|
CMOS checksum bad.
|
|
|
|
This should also be visible on over VGA output with a message stating this on a connected screen.
|
|
|
|
Probably the CMOS battery is empty, swap it, power cycle. Defaults are being loaded automatically.
|
|
|
|
## Misc
|
|
|
|
* USB keyboards work, e.g. to get into the BIOS by pressing F2 during boot |
