https://en.wikipedia.org/wiki/Long_mode
In the x86-64 computer architecture, long mode is the mode where a 64-bit operating system can access 64-bit instructions and registers. 64-bit programs are run in a sub-mode called 64-bit mode, while 32-bit programs and 16-bit protected mode programs are executed in a sub-mode called compatibility mode. Real mode or virtual 8086 mode programs cannot be natively run in long mode.

cpu does not support long mode. I've got a Tyan S2720 with dual Xeon 2.4G dual-core processors here that I was going to test out 64-bit support with. However, the system fails during boot of the...

x86-64 (also known as x64, x86_64, AMD64 and Intel 64) is the 64-bit version of the x86 instruction set.It introduces two new modes of operation, 64-bit mode and compatibility mode, along with a new 4-level paging mode. With 64-bit mode and the new paging mode, it supports vastly larger amounts of virtual memory and physical memory than is possible on its 32-bit predecessors, allowing programs ...

Apr 06, 2017 · The “x86” represents the instruction set architecture (ISA) that the processor supports. Intel line of processors were 286, 386, etc so we call the ISA x86 now. In the late 90s, Intel attempted a new ISA to support 64-bits with Itanium (IA-64). It...

I have Windows XP 64-bit, and am having a some weird issues with a 64-bit build of VirtualDub.In the release notes on SourceForge, it it says that the 64-bit version was compiled specifically for CPUs that support AMD64/x64 long mode.

Support for 2 MB pages is indicated by CPUID Fn0000_0001_EDX bit 3 (Page Size Extensions). It seems that AMD64 compliant CPU may not support this because this kind of check exists. Actually found that 2 MB pages are automatically supported in long mode. PSE support only refers to 4 MB page support in 32-bit mode.
