I did try 2.7, but this corruption happens well before MOS loads up. Gonna try to solder back pins R5 and R6, but doubt that will do me good. For a fact I know 2.7 runs good on my other 9200SEs, but 3.1 has black/white polygons scrambled.

I will try to hack at it some more to see if I can even get 256MB to work. Jim, is your 9800XT full 256MB on MOS?
