82845GV DDR SDRAM initialization

[Jia Jianwei]

     I'm now working on linux bios with 82845gv/82801db chipset. When I initialize DDR RAM, It's always hangs. When I enable NOP command and issue a memory read instruction, It hangs.  Anyone can tell me if I missed something? Any advice would be appreciated.

Best Regards,
Jianwei
