I'm not sure all clone boards use the same switch settings, but
here they are for the Super XT and MBE XT:

1:	OFF	Always

2:	OFF	8087 present
	ON	8087 absent

3,4:	OFF,ON	128K memory installed
	ON,OFF	192K memory installed
	OFF,OFF	256K memory installed
		(note - BIOS and DOS may choose to ignore these settings)

5,6:	ON,ON	no display adapter
	OFF,ON	color graphics (40x20 mode)
	ON,OFF	color graphics (80x25 mode)
	OFF,OFF	monochrome adapter or both

7,8	ON,ON	1 floppy drive
	OFF,ON	2 floppy drives
	ON,OFF	3 floppy drives
	OFF,OFF	4 floppy drives

Good luck with your clone.
