|V5 BIOS chips *can* be flashed in another I-Opener, say a V4. I have done so myself, as I posted earlier. The main issue is that the host machine (V4) should not be allowed to boot with the V5 BIOS, because it would then not be able to boot from an attached hard drive, or even from a non-V5 QNX image on the Sandisk. (I tried - even the V2 image with QNXFlash would not work, even if transfered to the Sandisk. Somebody ought to test this again, though, on a number of different units).|
So it will have to be booted with another BIOS image, preferably V1; then the V5 ROM has to be hot-swapped in. The ideal OS for doing this is DOS, because while DOS is idling at the command prompt, it does not use any BIOS calls, and you can safely substitute the BIOS chip at this point. Immediately after this, run AWDFlash 6.31 or AMIFlash (refered to in another thread) from the DOS command prompt. It worked for me, but the whole process carries the risk of hosing the chip and/or the host I-Opener for good, if you short out anything during the hot-swap.
