Int 13h extensions not supported when running produced .bin on virtualbox

Just a wild guess: Is the disk attached as IDE?

[fddnn]

no floppy controller. would that be the cause of this?

I found some information regarding int 13 extension issues here. According to that post:

Most real computers and Bochs support "int 0x13 extensions" for most/larger devices (hard drives, CD/DVD, etc), but don't support it for floppy disks.

So it might be likely that being attached as a floppy disk is what's causing the error.

I got the exact same with a floppy with VMWare. When I wrote it to an HDD, the boot worked.

Ok thanks that fixed it for me.
