China DOS Union

I use config.sys for multiple configurations. One of the submenus has 11 menuitem entries, but when I enter that submenu I find that only 9 menuitem entries can be displayed. Is there any way to make all 11 menuitem entries display and carry out their corresponding operations?

Usually people rarely need as many as 11 boot menus, but you can try the SUBMENU command. Its function is to split a menu item into another submenu. That is, when you choose that item, another string of submenus will appear, forming a tree structure. But first you need to categorize your boot menu. Its usage is as follows：

MENUITEM=DOS,START DOS
MENUITEM=WIN,START WINDOWS 98
SUBMENU=DOS2,DOS OPTIONS ...


MENUITEM=A,A MODE
MENUITEM=B,B MODE
MENUITEM=C,C MODE

I want to modify the boot menu of Wuyou Boot, please look:

; ******************* Main Menu *******************


MENUITEM=DOS,A:\.
MENUITEM=CDROM,Start Cdrom.
MENUITEM=GRAPHIC,Start Graphic Menu.
SUBMENU=MANAGE,Start Partition Manage >>
SUBMENU=BACKUP,Start Disk System Backup >>
SUBMENU=DATA,Start Data Recure Or Delete >>
SUBMENU=SETUP,Start Windows System Setup From CDROM >>
SUBMENU=TOOL,Hwinfo_Ntfsdos_Ucdos_Kv3000_Hdcopy_Dos Navigator >>
MENUITEM=HELP,View The Help File.
MENUDEFAULT=DOS,30
MENUCOLOR=7,0

; ******************* First-level submenu *******************


MENUITEM=PQPM,Partition Magic 7.0.
MENUITEM=PQSM,Server Magic 4.0.
MENUITEM=PQVM,Volume Manager 2.03.
MENUITEM=PQBM,Boot Magic 6.0.
MENUITEM=FDISK,Fdisk.
MENUITEM=SPFDISK,Spfdisk 2000-02d+.
MENUITEM=SFDISK,Smart Fdisk 2.05 rc2.
MENUITEM=DISKMAN,Diskman 1.20 Beta 3.
(MENUITEM=DMCN,DMCN)
(MENUITEM=OFORMAT,OFORMAT.)
SUBMENU=MENU,Main Menu <<<<
...................................

The two items in （） parentheses are the ones I want to add. As a result, it can only display up to the DMCN item.
Is there any way to make all of it display?

Of course there is. Try FreeDOS's CONFIG.SYS.
