Reset vector not mapped to address 0x0

Hello,
I have stripped a large project of all its files, except the startup file. Then I added USB support and adjusted the scatter file, like this:

; *************************************************************
; *** Scatter-Loading Description File generated by uVision ***
; *************************************************************

LR_IROM1 0x00000000 0x00004000  {    ; load region size_region
  ER_IROM1 0x00000000 0x00004000  {  ; load address = execution address
   *.o (RESET, +First)
   *(InRoot$$Sections)
    ;HTTP_demo.o (+RO)
    ;HTTP_CGI.o (+RO)
   .ANY (+RO)
  }
  RW_IRAM1 0x40000000 0x00010000  {  ; RW data
    ;HTTP_CGI.o (+ZI +RW)
;       *FS_ARM_L.lib (+ZI)
;       *TCP_ARM_L.lib (+ZI)
   .ANY (+RW +ZI)
  }
;  RW_IRAM2 0x7FD00000 0x00004000  {
;    LPC24_EMAC.o (+ZI +RW)
;;;   ;*FS_ARM_L.lib (+ZI)
;  }
  RW_IRAM2 0x7FE00000 0x00004000  {
;;    LPC24_EMAC.o (+ZI +RW)
;;   ;*FS_ARM_L.lib (+ZI)
        .ANY (+RW +ZI)
  }
  RW_RAM1 0xA0000000 0xA0FFFFFF  {  ; RW data
;;   ;LPC24_EMAC.o (+ZI +RW)
;;   .ANY (+RW +ZI)
;       SYS_DEF.o (+ZI +RW)
;;      SYS_FILESYSTEM.o (+ZI +RW)
;;      SYS_IO.o (+ZI +RW)
;;      SYS_DEF_EXT_RAM.o (+ZI +RW)
;;      SYS_MAIN.o (+ZI +RW)
;;      SYS_RTC.o (+ZI +RW)
;;      SYS_TIMER.o (+ZI +RW)
;       SYS_UART2.o (+ZI +RW)
        .ANY (+RW +ZI)
  }
}

the problem is that my reset vector is not mapped to address 0x0, see map file entry:

Can offer an explanation?
