http://svn.freebsd.org/changeset/base/197501 would not be bad if someone is from developers who are develop the amd64 looked at the problem this commit on arch amd64 this code p = BIOS_PADDRTOVADDR((regs.R_ES << 4) + regs.R_BX); if ((readb(p + 6) & 0x40) == 0) page fault ot access violation when try to readb from p pointer R_ES = 0xf000 R_BX = 0xe6f5 as result it is a bios rom area on arch i386 this works but not work on amd64 would be better to use BIOS_PADDRTOVADDR but we migrate to x86bios_offset to access rom bios area
