1) I wrote a 10M MS-DOS HDD installation completed in Bochs to the CF card. No boot from CF or MS-DOS floppy possible.
2) So, yes, I wiped the MBR on several ways. Like in 1) or by filling first 512 bytes with 0. (HxD on Windows helped here.)
3) I still found no way to boot MS-DOS, when I create a partition with FDISK. When exiting FDISK, you have to reboot. Afterwards it hangs booting from floppy again.

I also had some mail exchange with Eric Auer, which was at least a little help, but I gave up meanwhile. I will now just use a 2GB CF card from maxflash, which works fine. I already bought six used 1GB cards from the same brand on eBay for cheap.
