Very slow display after booting FreeDOS

[ssulser]

I have an old HP Pavillon x2 Detachable with an Atom Processor and 2GB RAM with 32GB eMMC Drive. I have installed one MBR partition and the computer is booting, CSMWrap is loading, but as soon as FreeDOS starts, the display gets very slow, you can even see the line by line construction of the display. And some Text concerning the CD-ROM ist printed in one Column. What could be the cause?

This is the limitation of SeaVGABIOS emulated VGA :-)
