Try these settings first. You can try to optimize performance later if everything works set this way:
FSB set as 100MHz
DRAM Clk at HCLK+PCICLK
Enhance Chip Performance - disabled
Force 4-way interleave - disabled
Enable DRAM 4k-Page Mode - disabled
Bank x/y DRAM Timing on SDRAM 8/10ns or Medium
DRAM Bank Interleave on Disable
MD Driving Strength - try HI and LO
SDRAM Cycle length on 3
Fast R-W Turn Around on Disable
