What make it different ? 1) arch==> i386  limit to 4G (dmesg) and  spdmem show 8G , Bios show 8G 2) arch==> amd64 memory show correct figure 8G (dmeag, spdmem and bios) 1 & 2 use the same machine with different arch. So can I use the i5 core at i386 arch to use the correct size of memory (i.e

Thanks.  I tried to use amd64 which show the correct memory size. Is there a way to use i386 to show the correct size of memory ?  The bios shows 8G memory.  Did I miss something to make it ? Clarence Stuart Henderson () 在 2020年6月11日星期四 上午12:41:40 [GMT+8] 寫道: On 2020-06-10, man Chan w
