I can boot with 004 parts though. 

When I get the board, The AMI BIOS does in the 040 part. I may did a sucessful flash on 040 part. I will check and report back. 

beneo

  004 only can be use in intel platform. FW hub interface...

  040 can be used in AMD platform. LPC interface...

  PMC 004 support two interface...

    It's SST 49LF004. It the replacement for SST49LF040. They use same argorithm to flash. I looked the flash_and_burn utility. That's the case there too. 

    beneo.

        YhLu,

        EEPOM should be SST 49LF004, sorry. 

        I also get the CPU version, it's a print out from cat /proc/cpuinfo. Total two CPU, I put the the second CPU here.

          EEPROM is SST 48LF004.

          I install 2GB to CPU0 and 2GB to CPU1. I use 512MB DIMM, 4 DIMM per CPU, so total should be 4GB. But linux command cat /proc/meminfo report one 2 GB when using LinuxBIOS.

          I have two opteron CPU, I'm not sure the version though.

          thanks

          beneo

            what is EEPROM in your BIOS socket?

            How do you install your DIMM? 4x1G in CPU0?

            What is your cpu version?

              I'm playing with the AMD seranede board. The flash_and_burn utility can not program linuxBIOS to the flash. but I can read the linuxbios and save to a file correctly.

              If I boot from AMI BIOS, using same utility, I can program a linuxBIOS into the flash. That made me believe some setting by linuxBIOS on the AMD Ref board is not right. I just don't know what.

              I used gdb to trace the code, Flash_and_burn utility enables flash by program two AMD Southbridge 8111 registers, One for enable 4MB window to flash (DevB, 0x43), one for enable write to the flash (DevB, 0x40). I checked the AMD datasheet, it seems all it need. But if I boot with LinuxBIOS, the flash erase command has no effect. with AMI BIOS, I can sucessfully erase a sector. 

              could anybody give me some pointer on what to check? 

              I should add, the linuxBIOS only reports 2GB memory when I really have 4GB in the system. I don't know if this have something to do with my issue.

              Thanks 

              Beneo
