Accessing Port I/O Via Kernel Device Driver
In Windows-based computers, memory can also be accessed via specific drivers such as DOLLx8KD which gives I/O access in 8, 16 and 32-bit on most Windows platforms starting from Windows 95 up to Windows 7. Installing I/O Port drivers will ensure memory access by activating the drivers with simple DLL calls allowing Port I/O and when not needed, the driver can be closed to prevent unauthorized access to the I/O ports.

Famous quotes containing the words port, kernel, device and/or driver:
“When we think back to our forefathers, with their sedentary lives of forest-chopping, railroad-building, fortune-founding, their fox-hunting and Indian taming, their prancing about in the mazurka and the polka, with their coattails flying and their bustles bouncing, to say nothing of their all-day sessions with the port and straight bourbon,... we must realize that we are a nation, not of neurasthenics, but of sissies and slow-motion sports.”
—Robert Benchley (1889–1945)
“All true histories contain instruction; though, in some, the treasure may be hard to find, and when found, so trivial in quantity that the dry, shrivelled kernel scarcely compensates for the trouble of cracking the nut.”
—Anne Brontë (1820–1849)
“Irony, forsooth! Guard yourself, Engineer, from the sort of irony that thrives up here; guard yourself altogether from taking on their mental attitude! Where irony is not a direct and classic device of oratory, not for a moment equivocal to a healthy mind, it makes for depravity, it becomes a drawback to civilization, an unclean traffic with the forces of reaction, vice and materialism.”
—Thomas Mann (1875–1955)
“God help the horse, and the driver too!
And the people and beasts who have never a friend!
For the driver easily might have been you,
And the horse be me by a different end!
And nobody knows how their days will cease!
And the poor, when they’re old, have little of peace!”
—James Kenneth Stephens (1882–1950)
