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 drive to get the DOS environment.
This article introduces 4 kinds of DOS boot disk

the CD-ROM to is used a lot, Cd,dvd, can erase write not erase all used, the price is also 2 to dozens of yuan range.Aside from the other, the unit price can buy the capacity, the hard disk occupies a small advantage, and the disc is probably the cheapest, most markets can buy 2.5 dollars 4.7GB of DVD, if the wholesale cheaper. However, most DVDs cannot be read and written, and they have no reference value. So the price is better than the hard drive.

ramdisknt and set it as follows:
1. Select 2.88 MB Floppy for disk type;
2. drive letter (drive letter). You can select any drive letter, but do not conflict with an existing drive letter! If your computer does not have a soft drive, set it to a and Check Start driver at boot;
3. Boot Sector settings (Boot Sector settings). Check the DOS Boot Sector;
4. Save image settings (Save image settings). Check Save
inches, single-sided 180KB. Later appeared double-sided 360KB. And then there are 3.5-inch double-sided 720KB. These are all low density floppy disks. Then came the 5.25-inch double-sided high-density 1.2MB and 3-inch double-sided high-density 1.44MB, until the last appeared 2.88MB. These all belong to high-density floppy disk.
. First, check whether your computer has an empty/mnt directory? This directory is used as a mount point directory. We recommend that you create multiple directories in/mnt:/mnt/CDROM,/mnt/floppy,/mnt/Mo, and so on as dedicated mount points for the directory.
For example, if you want to mount the following five devices, the command may be executed (assuming that all these are Linux ext2 systems. If win XX is used, change ext2 to vfat ):

/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.

It should be noted that the normal

Recently, the server encountered a small problem. I had to redo raid. I found an article on the Internet. I felt very careful. I 'd like to share it with you. Record the record when the server is reinstalled and share it with you.
Hardware RAID 5:
Recently, I personally assembled a 1u rack-mounted storage server with an 8-hard drive using a dual-core P4 820d processor. During the assembly process, I created a dis
Windows dynamic disk volumes: configuration operations for simple volumes, cross-zone volumes, with-zone volumes, image volumes, and RAID 5 volumes
Windows Server 2003 provides a new disk management method to improve disk performance and fault tolerance. By upgrading a basic disk
U disk must have 5 software
I believe you have more than one of the hands of a U disk. So, what can you do with your USB flash drive in addition to storing files? I'm afraid this is a problem that many friends often think about. So today, I would like to introduce you to a few small software, let them to help you "play turn" in the hand of the U
Today, the code is written to read and write floppy disk, the goal is to cross-track read and write operations into a number of single-track read and write operations. The idea is this: the first sector is located in the track of the sector read and write, and then modify the output parameters--Remove the part that has been read and write, recalculate the starting logical sector area code, the number of sec
To configure failover clustering for customers today, on Windows Server R2 systems, after Dell storage on the iSCSI connection, you can find new simple volumes, spanned volumes, striped volumes, mirrored volumes, RAID-5 volumes, and so on in Disk Management: Have never touched these before, so I learned a few online, the following are their introductionSimple volumeA simple volume is a volume in a separate
1. What is RAID5?
Raid Level 5 is a storage solution that combines storage performance, data security, and storage costs. It uses the Disk Striping technology. RAID 5 requires at least three hard disks. Instead of backing up the stored data, RAID 5 stores the data and the corresponding parity information on each
Soft RAID
I. Concepts
The stored data is separated and stored, and then staggered and stored on all disks that constitute the array.
1. The data read and write speed is greatly improved, but the read and write speed is lower than the total read and write speed of all disks.
2. the available space is the sum of all disk spaces.
3. data redundancy is not provided.
The disk stores the same data and provides
