The 440fx supports 8MB-1GB of memory. The default value for the DRBx registers is 01 (8MB). Bochs doesn't set the default value tho nor does the rombios set the correct one, so those registers stay with 0 values. If we set DRB0 and DRB1 to the CMOS values and keep DRB2 till DRB7 set to 0 we violate the assumption that DRB7 contains the top of memory value. In the all 0 case this is still somewhat valid. >> Hard coding the hole start to 0xe0000000, like you did in your first patch, looks like the >> easiest solution tho. > Yes, and I think it is good enough.
