Preface: DOS is a little difficult, mysterious, and far-fetched for people who have been familiar with computers since the Windows age. However, it cannot b

Since floppy disks and discs have largely been eliminated, the hard drive has also grown to large-capacity mechanical hard drives and high-speed solid-state drive (SSD) phases. Let's simply say the difference between these types of storage devices:1. AgeThe first was the floppy disk, then the disc and the hard disk. Bu

Q: In the msdn demo, replace the device name with "A:" and take the disk parameter. Read the disk with the resource manager, and then run the program, however, after changing the disk, it will fail.

In the first two sections, we loaded a piece of code into system memory through a floppy disk, and instructed the CPU to execute the code that was added to the memory, in fact, the operating system kernel was loaded. But we load the code, the maximum can only be a byte, an operating system kernel, less than hundreds of trillion, thus, the system kernel can not directly read into the system memory from the

But in Linux, it follows the way UNIX treats devices as files. So to access floppy disks and discs, you must first load them into the Linux system's/MNT directory. The loaded comman

Test platform: FreeBSD 4.5 release (i386) We may have seen many Linux operating on floppy disk, can run on floppy disk FreeBSD instead of less, although there are PICOBSD, however, many times Picobsd does not meet our needs, then can we make a floppy

Linux under the Firewall (firewall) from the birth to the present, the firewall has experienced four stages of development: the first stage: the firewall based on the router, the second stage of the user Firewall tool sets; Phase III: A firewall built on a common operating system; Phase IV: A firewall with a secure operating system. At present, most of the world's firewall vendors are provided with a security operating system hardware and software combination of firewalls, like the name of Netey
