Hello. When FreeBSD boots with 'boot -v' it show SMAP: SMAP type=01 base=0000000000000000 len=000000000009d800 SMAP type=02 base=000000000009d800 len=0000000000002800 SMAP type=02 base=00000000000e0000 len=0000000000020000 SMAP type=01 base=0000000000100000 len=00000000bfdb0000 <...> SMAP type=02 base=00000000fed1c000 len=0000000000004000 <...> Memory range 0xfed1c000 - 0xfed2000 belongs to ICH8 mapped to memory configuration registers. If I correctly understand mem man page, /dev/mem allow to read only real physical memory. How can I read data from this range? -- Alexandr Matveev
