How to create/convert floppy images?

[screw69]

I have a bunch of floppy images, which I need to boot the virtual machine to continue installing the OS from CD-ROM.
In particular these are OpenStep-4.2-intel boot floppies. These floppy images work just fine with Parallels. Since I want to run OpenStep in the background to replace aging hardware, it's either Parallels Server (at a ridiculous price of $1200+) or VirtualBox at a reasonable price ($0).

However, the floppy images I have are rejected by VirtualBox, even though they work just fine with Parallels. An attempt at converting them with

Code: Select all

VBoxManage convertdd 4.2_Install_Disk.fdd 4.2_Install_Disk.vdi

didn't result in a bootable floppy image, either. What's the trick?
