[gPXE] Booting FreeDOS - beginner question

[Ruzsinszky Attila]

>>and then use qemu to populate the image "qemu
>> -hda image.bin -cdrom freedos.iso".
I don't understand why didn't work with sanboot.
The fdisk+format (maybe) were successfull. Even the
result was: Invalid Operating System. I know the setup hadn't
finished but what changed at the 2nd boot what resulted
Inv. OS message.

I'd like to understand ...
Maybe am I too stupid? ;-)

TIA,
Ruzsi
