That is not the problem. The problem is that the BIOS in version 0.9.4 fails to set DS to its data segment if it encounteres an an unsupported function
https://github.com/skiselev/8088_bios/blob/6da84ae09804002ae29080cd64dc85e58f46ae9f/floppy2.inc#L89
https://github.com/skiselev/8088_bios/blob/6da84ae09804002ae29080cd64dc85e58f46ae9f/floppy2.inc#L94

But it writes to it at https://github.com/skiselev/8088_bios/blob/6da84ae09804002ae29080cd64dc85e58f46ae9f/floppy2.inc#L128

In later versions that seems to be handled differently, an the current binary for Xi8088 seems to work under 86box.
