i'm not sure the q-flash sees flash drives
here is how you make a
usb flash drive bootable i.e. get a dos prompt:
http://i.thepcspy.com/USB_Boot.zip (pasta is the password to unzip, not sure why it is password protected).
run the utiliy (BACK UP USB DRIVE FIRST AS IT FORMATS IT) and then copy the files autoexec.bat etc in the other directory onto the usb
after you have run the install.
then copy your new bios and the flash895 exe on there. once you boot, run the flash895.exe using the switches pointing to the new bios. i dont know the switches off the top of my head so run:
flash895.exe /?
