Booting from Flash

I am having a custom X86 based board with bios & AmdFlash,Floppy drive
I customised theFlash driver for it from sc400 bsp.
I am able to boot from the Floppy (image in floppy)& then if i run the flash
driver i can use the flash ie mount it, copy etc.
Now i want to put my Image in Flash & boot from it.
How can i go about it.
I am using the bios.
