想是一下，但是不是直接给我IMG文件，而是需要3.5英寸用如下步骤的
1) Place a blank, formatted 1.44MB floppy disk in drive A.

2) In a DOS box, go to the directory where the software was
installed. Probably "C:\DL\ROMDOS SUV"

3) Go to the directory of the version of ROM-DOS Single User Version
you want to use: "622" for ROM-DOS 6.22 or "71" for ROM-DOS 7.1.

4) To make the floppy disk bootable, type the following command:

C:\DL\ROMDOS SUV\622\> SYS A:
or
C:\DL\ROMDOS SUV\71\> SYS A:

5) Copy all the needed files onto the floppy disk with the following
command:

C:\DL\ROMDOS SUV\622\> XCOPY *.* A:
or
C:\DL\ROMDOS SUV\71\> XCOPY *.* A:

You can choose not overwrite "COMMAND.COM" when prompted.

6) The disk is now bootable and contains ROM-DOS Single User Version.
