If the system uses flash storage instead of IDE it could also use flash 
for the BIOS. The above comments are correct about doing the switch but 
why boot from flash and switch to IDE? If it is an IDE based storage 
system put the BIOS on LPC like normal.

A way to work around the image source problem is to use a USB drive.
