To prevent possible data loss will not continue further here the entry in menu.lst: title addh from partition 0map --unmap=0:0xffmap --unhook && map --rehookcat --hex --locate=PoLPu@ (md)0x3D0+0x130 > nul && echo Cannot continue if PLoP is active, please start this entry without loading PLoP first && echo && pause Press any key to return to the main menu && configfile /menu.lstset /a dev=*0x8280&0xffroot (%dev%,0)set ISO=/ISO/addh.isols %ISO% > nul || find --set-root --devices=hf /usbdrive.tag|| echo Error!
