map in Chinese means drawing a map of...; understanding information and providing information (especially its arrangement or organization).

map in the computer command is used to virtualize the image file into a floppy disk.

One of GRUB's built-in commands: map, used to virtualize the image file into a floppy disk

Usage:

map ( hdx,y)/directory/file name (drive letter)

chainloader (hdx,y)/directory/file name

*Note: GRUB uses the UNIX method of naming devices. That is (hdx,y). x is the hard disk number and y is the drive letter. Start counting from zero. The first extended partition is numbered 4.

Startup command example (Mini-Windows 3.2 startup disk):

map (hd0,0)/boot/pmwin3.img (fd0)
chainloader (hd0,0)/boot/pmwin3.img
boot

Menu example

MAP must require image files to be stored continuously, otherwise it cannot be started. It does not limit the file size.
