Update on the notion- I looked at the two different bioses in a hex-editor, and they are radically different in terms of code placement starts and stops.
Frankly, our Arima is just weird and unconventional- I've looked at a few others in my time, and this don't make much sense to me. The Acer code begins at the standard and conventional 1000h position- the Arima code, for both eMachines and Targa flavors have some code at the very 0000h beginning, and then followed by a whole bunch of nothing- so that leads me to speculate it is an immediate jump to actual code way further in.
That difference, then, leads me to believe that the different boards could also be using different ROM chips, which would, in turn, follow different boot sequences....which in turn would throw a total wrench into the notion of easily injecting code from one to the other.
At this point, it looks(to me, anyway) that you'd have to find out A) if these boards use different or the same Bios chips B)- if different, somehow find some code mappings as to what instructions are expected where.
C) Assuming they're different, you'd have to solder the Acer chip into the Arima board for starters.
Now there's several hacks out there which involve injecting different splash-screen bitmaps into different bioses, but that's basically kiddie stuff compared to this, imo- I mean, yeah, cool, have it boot with your name or a cool racecar bitmap or whatever, but that doesn't change any hardware control. And I know another guy who bricked his laptop just trying to do that- so, to me, that's a waste of effort vs. the return. whatever-
So, at this point, but not before
- I'd have to reluctantly agree with Thunder and Anaconda that proceeding with just trying to flash the Acer bios looks very much like Bricktown.( those of you who've been to OKC know what that is
) This "could" be a lot of fun.......
If anyone knows of any yahoo type forums on this sort of stuff, please let me know about it- I've got a stack(haha) of classic Assembly books that I've kinda looked at- and "some" C programming knowhow, but there's nothing like a project like this to actually get motivated to master that stuff.
