This article mainly explains "how to use the memory virtual disk software xmsdsk". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to use the memory virtual disk software xmsdsk".

With the development of the times, the memory of computers is getting larger and larger, from the original 1m, 2m, 4m and so on to 128m, 256m, 512m, or even larger. Therefore, it is very important to allocate and use memory reasonably to avoid unnecessary waste. Moreover, compared with general external storage devices, such as disks (including hard disks, optical discs, etc.), memory has many advantages, such as the speed of memory is very fast, usually dozens of times faster than the latter; the capacity of the disk is limited, especially the floppy disk, the size of a floppy disk is generally only 1.44m, so the boot disk often can not hold the required programs. Therefore, if memory can be used as a disk device to store files and data, it can undoubtedly greatly improve the speed, efficiency and convenience of operation, and can maximize the effectiveness of memory, that is, the effective use of memory.

For this reason, people have developed a lot of memory virtual disk programs, such as VDISK.SYS, RAMDRIVE.SYS and so on, which are included in DOS. However, these programs all have some disadvantages, such as they need to be loaded in a CONFIG.SYS file and cannot be loaded directly on the DOS command line; once loaded, the memory disk cannot be resized or deleted; the memory disk has a capacity limit and usually cannot exceed 64m; and they themselves take up more regular memory. Now someone has finally developed a memory virtual disk program that solves all the above problems, and that is the XMSDSK (which can be downloaded in the disk tool).

XMSDSK is a relatively new program, and it is quite powerful, practical and stable. It is one of the Furd memory toolkits, so the name is to use XMS memory to create disks. Therefore, it can only be used if it has XMS memory, usually as long as you load the HIMEM.SYS program that comes with DOS (in the case of MS-DOS, it is best to use version 7.10 or above to allow HIMEM.SYS to support more than 64m of XMS memory), and then you can use it as you like. XMSDSK has too many benefits, such as the ability to dynamically resize or disassemble a memory disk an unlimited number of times in command-line mode, in addition to being loaded in CONFIG.SYS. It takes up very little memory, only a few hundred bytes of low-end memory, and can be automatically called into UMB (upper memory block) without the need for the LH command. It supports a huge amount of memory (currently up to 2G), so for example, we have 512m of memory, and we can even virtualize all the XMS memory into disk. If you use it in the boot disk, you can add a lot of color to the boot disk. It also has a very useful use, because some software, such as some game software (such as Chinese Paladin), can only run in memory below 32m, so you can use XMSDSK to install memory disks so that the free XMS memory is less than 32m, so that those software can run normally. Most importantly, it is very easy to use, so let's introduce how to use it in practice.

The syntax for using XMSDSK is as follows:

XMSDSK [memory disk size] [drive] [options]

Among them, the memory disk size is represented by KB, for example, 4 means 4K memory disk 1024 represents 1024K=1M and so on, if not specified, a 0K memory disk will be created. The drive represents the drive letter of the memory disk to be specified, and if not, it automatically uses the next drive letter. For example, if there are only A, B, C and D disks in the current drive, the memory disk will be automatically loaded on the E disk. The options are as follows:

/?: view command line help

/ Y: when performing an operation, no confirmation is required, that is, the default is "Yes (Yes)"

/ U: remove the memory disk and exit the memory.

/ T: position the memory disk at the top of the XMS memory

/ C: specifies the cluster size of the sector in the memory disk.

Usually only its / Y and / U options are used.

When you run XMSDSK without any parameters and options, that is, when you enter the XMSDSK command directly, you will be prompted whether or not to load XMSDSK if it is currently loaded; otherwise, it will automatically display the status information of the loaded memory disk, such as the size of the memory disk.

Here is an example of the use of XMSDSK. For example, if you now want to create a 5m memory disk, then adjust it to 10m, and finally delete the memory disk to free up the drive letters and used memory, and do not confirm when installing, adjusting, and deleting, you can enter the following commands in turn under the DOS command line:

1:XMSDSK 5120 / Y (create a 5m memory disk)

2:XMSDSK 10240 / Y (resize the established 5m memory disk to 10m)

3:XMSDSK / U / Y (delete loaded memory disk)
