Yes, I *have* looked at the help and faq... anyway...
I have been working with get/set discriptor functions a know what *most* of the
bit's in the 8 byte selector string thing (like the segment limit, base
address, and granular etc...), but these have eluded me :(
Thank you any and all help :)
- type of what?
[5] ---- XXXX = type
- does this have to be application?
[5] ---X ---- = 0=system, 1=application
- what type of privileges... 1=reading, 2=writing, 3=reading & writing?
[5] -XX- ---- = priviledge level
- i don't have a clue what this is for... segments? what does making the to
present
do compared to having them absent?
[5] X--- ---- = 0=absent, 1=present
- what good is this for? will i ever need it?
[6] ---X ---- = available for user
- another one of those things i'm completely unaware of it's purpose...
[6] -X-- ---- = 0=16-bit 1=32-bit (cs only)

P.S. just a link to a page, or document would be enough
(i've seached the web, but haven't found anything usefull)
