Hello Sir(s),
 
Following is my modified/corrected syslinux.cfg file
 
#
# main entries
#
 
#  menu label ^0. xxxx  -->This IS displayed
# Following IS Recomended:>boots MBR 
 
label local-boot

menu label ^0. Boot MBR

kernel chain.c32
append hd0 0
 
# this  boots WinXP/Win98/Win2000
  menu default
  menu label ^1. Boot WinXP/Win98/Win2000
  kernel chain.c32
  append hd0 1           
 
LABEL cmdcons 
MENU LABEL ^2.cmdcons  
 COM32 chain.c32  
  APPEND hd0 1 cmldr=cmldr
 
LABEL grub4dos
MENU LABEL ^3.grub4dos    
COM32 chain.c32  fs grldr=/grldr/grldr
  APPEND file=/grldr/grldr
 
LABEL nu2-2
MENU LABEL ^2. INSERT\partimage             
 kernel /DiskImages/memdisk
  append initrd=/DiskImages/BtInsUSB.img 
               
LABEL nu2-4
MENU LABEL ^4. Partition Magic8  
 kernel /DiskImages/memdisk
  append initrd=/DiskImages/Pm8.img
 
LABEL nu2-5
  MENU LABEL ^5. Plpbt.
  KERNEL linux.c32
  INITRD /ISOimages/Plpbt.iso
  APPEND /ISOimages/memdisk iso
 
#OR
 
#LABEL dir
#MENU LABEL display files in /ISOimages/
#COM32 ls.c32
 # APPEND /ISOimages/memdisk iso raw

Following are the results for your information please:
 
menu label ^0. Boot MBR   and    menu label ^1. Boot WinXP/Win98/Win2000
both operate OK.
                                                          
[1]
for  MENU LABEL ^2.cmdcons: 
 
get  the following display:

 takes   @ 1Min to load  & then Boots in GUI
