Update: I could only update bios by changing name of file that ez flash keeps looking for, p4p800-e.rom. I updated from ver 1002 to 1009 this way. But I can't get slic bios to write even if I change name to p4p800-e.rom. I get error: rom file romid is not compatible with exsiting bios romid. Here is backup of bios already flash to system. I hope this helps. Thanks in advance.
