Well, you can. At least, you can if you are running a gigabye ep43-ud3l mobo. I posted a thread on here previously about having touble flashing. After trying multilbe methods, I finall took a leap of faith. I grabbed my psp, formatted the mem stick to fat32, loaded the psp with the bios update ONLY, and updated in q-flash. Please note that I do have custom firmware installed on my psp, although I dont think that it makes a lick of difference, seeing as you can use the psp as a "removable disc" regardless. I would be curious to know if this can be done on other mobo makes and models as well. Happy flashing!!!!
thats very intresting but why would you go to all that trobule when u can just make a bootable usb key with whatever on it
