table always starts from I/O address 0, but you can choose not to provide the bitmask for upper I/O addresses. Any part of the bitmask that you do'not provide is assumed to be 1, and therefore, access is not granted to those ports.
The bitmask array, called the I/O Permission bit Map (IOPM), is stored in the Task State Segment (TSS) structure in main memory, which is contained in a special, segment referenced by the segment selector in the processor' s Task Register (TR) . The location of the IOPM within the TSS is flexible. The offset of the IOPM within the TSS is stored in a 2-byte integer at location Охбб in the TSS.

Listing Three
/*From inspection of the TSS we know that NT's default IOPM offset is 0x20AD.
From an inspection of a dump of a process structure, we can find the bytes 'AD 20' at offset 0x30. This is where NT stores the IOPM offset for each process, so that I/O access can be granted on a process-by-process basis.
This portion of the process structure is not documented in the DDK. This kernel mode driver fragment illustrates the brute force method of poking the IOPM base into the process structure. */

Существительные с предлогами
Грамматика этого урока разнообразия ради рассчитана только на запоминание.
Фиксированные сочетания предлогов с существительными надо учить наизусть. Их правильное употребление в устной и письменной речи — хороший тон.
Как мы уже поняли, служебные слова крайне важны в английском, предлоги в частности. Есть два момента, которые надо помнить, имея дело с английским существительным:
1) С существительными надо употреблять правильные предлоги.
2) Знать точное расположение предлогов — до или после существительного.
§ 1. Предлоги с существительными надо употреблять правильно, если вы хотите правильно понять ситуацию.
V In the end — наконец, результат ситуации, at the end — в конце; то, когда происходит ситуация.
At the end of the work we got the results and in the end we understood that the solution of our problem was very easy.
time — пунктуально, не поздно, in time — достаточно быстро для чего-то, чтобы сделать что-то.
We hope to obtain the results on time. We hope to get your remarks in time to debug the program.
Более того, есть существительные, которые требуют совершенно определенных предлогов, и их лучше замечать и заучивать, внимательно читая любой английский текст.
