RouterOS V6.x installation on APU3a2 (PCEngines)

RouterOS General

Hello,

I am trying to install RouterOS from mikrotik on a apu3a2 board. I have tried several ways with no success.
Install from SDcard, mSata, USB always ending up with

SYSLINUX 3.84 2009-12-18 EBIOS Copyright (C) 1994-2009 H. Peter Anvin et al
Loading linux…
Loading initrd.rgz…ready.
Welcome to MikroTik Router Software hard disk installation 6.34.5
Press Ctrl-Alt-Delete to abort

Loading drivers
Looking for harddrives…

FATAL ERROR: No hard disk found
Press ENTER to reboot

I have read several threads about successful installations with ALIX or APU boards but none with the newest one like APU3.

Any help would be very appreciated.

Thank you very much for your time..

Are you in BIOS mode and AHCI SATA enable?

I cannot change any BIOS settings so i dont know if it is AHCI, SATA, or IDE mode

If i remember it as to be IDE mode. Why you can not acces the Bios setup?

The only BIOS setting i can change is the boot order between devices msata, usb, sata. Maybe, RouterOS is not a choice for this board.
