There is no device in /dev called fb, and I want to know how you create this?
This is what the /dev/fb* devices are on my system:

crw------- 1 root 68, 0 Aug 30 17:34 /devices/pci@1f,4000/TSI,gfxp@4:gfxp0
This means, the actual
/dev/fb0 is only a link to
/dev/fbs/gfxp0, which also is a link to
/devices/pci@1f,400/TSI,gfxp@4:gfxp0
The device is a charactor device, which you would make with the
mknod(1M) command. And from my output, you can see, the device has a major of 68 and a minor of 0, so if you were to create this specific device the command would be:
mknod /devices/pci@1f,4000/TSI,gfxp@4:gfxp0 c 68 0

fdformat
FDFORMAT(8) Linux Programmer's Manual FDFORMAT(8)
NAME
fdformat - Low-level formats a floppy disk
SYNOPSIS
fdformat [ -n ] device
DESCRIPTION
fdformat does a low level format on a floppy disk. device is usually one of the following (for floppy devices, the major = 2, and the
minor is shown for informational purposes only):
/dev/fd0d360 (minor = 4)
/dev/fd0h1200 (minor = 8)
/dev/fd0D360 (minor = 12)
/dev/fd0H360 (minor = 12)
/dev/fd0D720 (minor = 16)
/dev/fd0H720 (minor = 16)
/dev/fd0h360 (minor = 20)
/dev/fd0h720 (minor = 24)
/dev/fd0H1440 (minor = 28)
/dev/fd1d360 (minor = 5)
/dev/fd1h1200 (minor = 9)
/dev/fd1D360 (minor = 13)
/dev/fd1H360 (minor = 13)
/dev/fd1D720 (minor = 17)
/dev/fd1H720 (minor = 17)
/dev/fd1h360 (minor = 21)
/dev/fd1h720 (minor = 25)
/dev/fd1H1440 (minor = 29)
The generic floppy devices, /dev/fd0 and /dev/fd1, will fail to work with fdformat when a non-standard format is being used, or if the for-
mat has not been autodetected earlier. In this case, use setfdprm(8) to load the disk parameters.
OPTIONS
-n No verify. This option will disable the verification that is performed after the format.
