hello guys
i'm writing a lib to used in os construction, it just contain the function that must be written in assembly. when i set the IDT and loads it, GPF occurs, and bochs says the problem in the isr, but how isr works and prints the message in GPF ?. may be because of tss i didn't set one or so. i hope any body can revise my code and tell me the problem, i will really appreciate that. thanks alot

The most important part is 00127550225e[CPU ] iret: AR byte indicated non code segment . but i check the cs stat on return from int 13 and found it 8 which is my cs with base 0 and limit 4 gb  _________________ Maslan I'm searching for perfection so, even if u need portability u 've to use Assembly --- http://www.maslanlab.org --- http://libosdk.berlios.de http://maslanedit.sf.net http://maslancms.sf.net |
