Hi, here is an attempt of dump I made but I am not really confident it worked.

At a first glance, from an hex editor, I don’t see any meaningful information.

[code]

sudo grep ROM /proc/iomem

000f0000-000fffff : System ROM

sudo dd if=/dev/mem of=teclast.f6.plus.bios bs=64k skip=15 count=1

[/code]
