First explain the various operating systems to boot to the DOS path:
Win9x system: After the boot press F8, select the 5th entry, you can enter the system with the basic dos7.x environment.
2K/XP/2003: The system does not come with DOS, it needs a DOS boot disk or a virtual floppy

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. If you change to "cdrom0", the CDROM parameter will not work in any case. How can this problem be solved?
A:
The floppy
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
Most of the time, we may all need to involve reloading the system, w764 flagship system download is very powerful, but at the same time, the system is also very fragile, may be a wrong operation, wrong clicks, will cause the system to damage, may be deleted a file, will lead to Win7 flagship system confusion, this time , perhaps the best solution is to reload the system, so what is the best way to reload the system, now many friends like to use U disk
First, since it is a floppy disk, we can try to disable the floppy drive in the Device Manager, in My Computer--Properties--hardware--Device Manager, select the floppy disk drive, click Disable, Note: to the bottom of the floppy
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
Summary
This paper gives the realization of the floppy disk image generation tool, and uses it to make a floppy disk image by compiling the generated boot file, and writes the floppy disk
File System for Linux: ext2
Optical Disk File System: iso9660
Although vfat is a FAT 32 system, it is actually compatible with the file system type of fat 16.
2. Determine the device name
In Linux, the device names are usually in/dev. These device names are named in a regular manner. We can find the device names in the form of "push.
For example, the/dev/hda1 ide device. HD refers to hard disk,

/floppyfw/download/first to download FLOPPYFW to your computer's hard disk. FLOPPYFW the latest version should be 1.0.5 or higher, FLOPPYFW is a mirrored file that can use # dd if=floppyfw-1.0.5.img of=/dev/fd0 bs=72k
This command extracts the mirrored file and writes it to a prepared floppy disk.

One: The redundant startup items in the boot.
We all know that the computer will run some software on the boot, if the computer has too many boot startup items, not only affect the computer boot speed will also be a system error, so we want to turn off the redundant
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

The Linux Firewall named floppyfw can be stored in a general floppy disk and run independently in RAM memory. Use it to start the computer, use ipchains to filter out useless IP pac
