Hi,
This is regarding IDT on windows. I have modified unsused Interrupt descriptor (indexe 0x1e). And i am trying to execute the modified interrupt from user level program...
INT 1Eh
This is causing Access voilation error. When i tried with
INT 2Eh
the user program running successfully. What i understand is only some descriptors will allow to execute from user level (ring 3). And i tried modifying the 1Eh index previleges similar to 2Eh index. But still i am facing same access violation issue.
Please help me if any of you have idea onthis.
Thanks
