5 25 floppy 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.

. 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 ): 1.

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.

the FreeBSD boot process, now that we are ready for the bootstrapper and loader, we have to prepare the kernel. 3. Custom kernel Floppy disk space is limited, so we need to customize a small kernel, not directly using the system's original kernel. Since we only use floppy disks, the kernel's SCSI, ATA, ATAPI, and RAID items should be removed because we don't

/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. About settings: It should be noted that the normal

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

1, if the computer has a floppy drive appear in such cases, because the floppy drive was used when the computer was last shut down, but the software was removed directly from the system window, so every time I called my PC, I was prompted to insert the floppy drive, and the solution was to insert a floppy

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
