It seems that I am not able to place the primary partition at the start of the address space.
When I look at it with gparted, it is showing 8Mb of free space before the primary partition.

that doesn’t matter. SeaBIOS boots from the MBR (first ~440 bytes of drive) which contains the partition layout and location of the PBR (eg, grub) so those 8MB are inconsequential
