I have this thin client with non standard 64mb flash drive. I want to install ms-dos on it using usb and be able to boot flash hdd.

Using rufus doesnt work because usb is seen as drive1 and flash hdd seen as drive2, so I cant set flash hdd active in fdisk.

Using unetbootin also did not work. Although is boots from a virtual floppy A:\ drive, it still sees usb as drive1, so same problem.

Is there a program like rufus or unetbootin, that would make usb dos boot as A:\ floppy, but not seeing usb as drive1 ?

Just boot as A and see flash hdd as drive1 so I can set it as active in fdisk.

Thanks in advance.

I guess it's theoretically possible to spoof a disk as int13 device 0 at the high level (some rather modern motherboards with AMI EFI allegedly have this feature, like my Gigabyte C847N), but here are some alternatives that are here and available now 😀

- bootable CD (El Torito is by far the most common non-hardware virtual floppy drive)

- "Free FDISK" (which, guess what, is the stock partitioner in FreeDOS) can install the MBR to any HDD (well, at least the first 3 😁 )

- and so can Ranish, and probably more 3rd party partitioners, worst case scenario you could copy the whole MBR with a sector editor or even Debug 😀
