Segments in Real mode on the Intel x86 architecture overlapped, which is poor design.

I removed this because Wikipedia should not pronounce judgement on what's good and what's bad design. It was tempting to leave it in with the weasel phrase "Some feel that...", since I do feel it's poor design, but I resisted. - furrykef (Talk at me) 02:42, 24 October 2005 (UTC)[reply]

Segments in Linux

“The Linux kernel sets up only 4 segments…” Really? Doesn’t Linux use TSS segments as well? And some others? Understanding the Linux Kernel (2nd edition) says so about the 2.4 kernel. Don’t know whether it’s true for the 2.6 kernel as well…

Linux only uses 4 memory segments. Task State Segments are different and Linux only uses 1 of them. A few other miscellaneous segments (for APIC stuff I believe) are used, but the kernel and userspace only use the 4 segments listed. I suppose that could be made a bit more clear...
