We need a system to run old DOS program. Microsoft's Win98 lacks proper memory management for modem computer with larger amount memory. We have PC-DOS (from IBM) lay around.
Basic setup: Syslinux + floppy image with boot.bss
Need create a empty floppy image on usb drive.(your usb is already fdisk with FAT16 partition, and mkfs.msdos formatted).
Code:
#mount -t msdos /dev/usbpartition# /mnt/usb
#cd /mnt/usb
#dd bs=512 count=2880 if=/dev/zero of=fd0.img
...
