256 MB, but that's arbitrary; just the preference I have set in  
Parallels.

I don't know how to obtain this information, but would be glad to  
supply it. Also, forgive my ignorance, but isn't there a chicken-and- 
egg problem, since if the MTRRs are set up in vgavesa.c, my display is  
unusable? Or is there a special way to bail out to the text mode when  
the display is screwed up?

Thanks again,
