Greetings,
It might accept an 82802aC which is a 1MByte part (nice tiny distinction in the part number eh?) Electrically, there's no problem at all. The challenge will be to get the chipset to route memory accesses from fff00000 - fff7ffff correctly. That may be a register configuration.
I don't know much about i810. It may even already be routing those addresses. If so, fff00000-fff7ffff will appear to be a duplicate of fff80000-ffffffff when the smaller (original) flash is inserted. At least that's what happens when I put a 512KByte part in a Clearwater board (which normally has the 1MByte part).
G'day, sjames

I have a Tekram S381-ML motherboard (http://www.tekram.com/hot_products.asp?Product=S381-M) with a i810 chipset on it. In one corner there is what I belive to be the flash part. It is a socketed chip labled N82802AB. I belive it is only 512KB. Is there any chance that I could throw a larger part in there?
