- NAME
- MOUNT - Virtual memory disk creator
-
- SYNOPSIS
- MOUNT drive: [-m=nnn] [-s=nnn] [-d=nnn] [-c] [/c ...]
-
- DESCRIPTION
- Mount initializes a virtual disk in memory and tells the
- ram disk driver where the disk is located.
-
- The -m option tells mount how much memory to allocated to
- the disk. The default size is 64K.
- The -s option tells mount what sector size to use. The
- default size is 128 bytes.
-
- The -d option tells mount the number of root directory
- entries desired. The default is 64.
-
- The -c option displays an extended copyright notice.
- The /c option tells mount to execute the remainder of the
- command line after the disk has been allocated. Mount then
- dismounts the disk automatically. This is useful for
- running programs such as compilers where temporary files
- can be redirected to the memory disk.
- If /c is not specified, the default shell is executed.
- MOUNT with no parameters prints a usage guide.
-
- SEE ALSO
- RMVRAMDK (4)
-
- DIAGNOSTICS
- Unrecognized parameter on command line : %s - ignored
- Drive %c: is not a mountable device - this disk is not
- associated with a RMVRAMDK device driver.
-
- Error performing ioctl query. Returning to DOS
- Error performing ioctl output: Returning to DOS
- Drive %c: is already mounted - The device driver already
- has a disk.
- Do you wish to dismount virtual disk %c: ? - Upon exit,
- this gives the option of returning to the shell without
- losing the disk
- The requested disk size %uK is outside of the range %uK -
- %uK ... The requested sector size %u bytes is outside of
- the range %u - %u ... The requested number of root entries
- %u is outside of the range %u - %u ... - These three
- messages are used to indicate invalid command line
- arguments. They are followed by the message :
- Using the default size
-
- Number of root directory entries has been updated to %u
- .... Disk overhead is greater than the disk size ... -
- These messages tell of modification made by the program
- when the disk parameters were being calculated.
- Insufficient memory to create virtual disk
- Insufficient memory for buffer: Returning to DOS
- Not enough memory to allocate device stack
- Not enough memory to create shell or Could not find shell
- program
-
- BUGS
- Logically, this program should be dismounted using a
- program, typically UNMOUNT. However, the best way to
- protect an area of memory in MS-DOS is to shell a command
- processor after the area. Terminate and remain resident
- makes freeing the area a major chore which can destroy
- DOS's memory management.
-
- One must use EXIT to exit from the shell back to mount.
