This allows the trusted operating system and drivers running in kernel mode to access the ports while preventing less trusted user mode processes from touching the I O ports and causing conflicts All user mode programs should talk to a device driver which arbitrates access The I O permission bitmap can be used to allow programs not privileged enough l e user mode programs the ability to access certain I O ports When an I O instruction is executed the processors will first check if the task is privileged enough to access the ports Should this be the case the I O instruction will be executed However if the task is not allowed to do I O the processor will then check the I O permission bitmap The I O permission bitmap as the name suggests uses a single bit to represent each I O address If the bit corresponding to a port is set then the instruction will generate an exception however if the bit is clear then the I O operation will proceed This gives a means to allow certain processes to access certain ports There is one I O permission bitmap per task ESA PCIDIOT User Manual Page 46 of 60 Accessing I O Ports under NT 2000 XP There are two solutions to solving the problem of I O access under Windows NT 2000 XP The first solution is to write a device driver which runs in ring 0 I O privilege level 0 to access your I O ports on your behalf Data can be passed to and from your user mode program to the device driver via IOCTL calls The d
