On WRT 3200 acm
Change the boot order as you prefer.
For your needs change the paths to a) scsi or usb , b) 0 or 0:1 depends from your partition scheme, c)/workingfolder/rango.img
Rename your Firmware image to rango.img (WRT3200acm codename) and put it to the right path /workingfolder.
...This the trick
-nandboot 1st try from scsi port ,if fails then try to boot from usb port ,if fails boot from nand2 = /dev/mtdblock8 = Dd-wrt
-altnandboot 1st try from nand 2 =Dd-wrt ,if fails then boot from nand1 /dev/mtdblock6 = Original Linksys firmware.
-uboot =Better never need it! But i believe will be uselless that time.~~
