I read the article about segmentation written by tony lawrence. i have a question to ask on this subject. suppose that we are in protected mode and we have entered 3 segment descriptors(1 for data, 1 for code, 1 for the stack). each has its own base and limit.
and as you all know every executable program consists of data,code,bss etc. segments. could anyone prepare a scheme and document which shows:
1) when you load 2 executables into the memory, how and where its own segments are located in memory using the gdt?
2) how can we define those segments in gdt, i mean data,code and stack? how will we tell the gdt which is what segment?
that is all for now.
thanks in advance for the answers.

There are kernel books that cover that kind of detail.. I forget whether http://aplawrence.com/Books/linuxappdevel.html gets that deep (most of my books are still packed from our recent move and I can't easily get at them) but it might.
