Subject: Re: [LinuxBIOS] flash issue with AMD Ref boardIt'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.----- Original Message -----From: YhLuTo: beneo ; linuxbios@openbios.orgSent: Thursday, May 12, 2005 9:53 AMSubject: RE: [LinuxBIOS] flash issue with AMD Ref boardSST49LF004 or SST49LF040 ?YH

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.thanksbeneo----- Original Message -----From: YhLuTo: beneo ; linuxbios@openbios.orgSent: Wednesday, May 11, 2005 7:27 PMSubject: RE: [LinuxBIOS] flash issue with AMD Ref boardwhat is EEPROM in your BIOS socket?How do you install your DIMM? 4x1G in CPU0?What is your cpu version?YH

Subject: [LinuxBIOS] flash issue with AMD Ref boardI'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.ThanksBeneo
