Hi Oliver,
I checked the PB docs and made the following changes to the platform files:

In platform.bib file:
----------------------------------------------------------------
; @CESYSGEN IF CE_MODULES_DISPLAY
IF BSP_NODISPLAY !
IF IMG_NODISPLAY !
;
; MGDI NOP Display driver
IF BSP_DISPLAY_NOP
   ddi.dll $(_FLATRELEASEDIR)\ddi_nop.dll NK SH
ENDIF

ENDIF IMG_NODISPLAY !
ENDIF BSP_NODISPLAY !

; SMI Display driver
IF BSP_DISPLAY_SMI
   ddi_smi.dll $(_FLATRELEASEDIR)\ddi_smi.dll NK SH
ENDIF
; @CESYSGEN ENDIF CE_MODULES_DISPLAY
-----------------------------------------------------------
In platform.reg file:
-----------------------------------------------------------
IF BSP_DISPLAY_SMI

; @CESYSGEN IF CE_MODULES_PCI

; GWES will be able to auto-detect the display adapter if a candidate value
; points to the adapter's PCI instance. Values from Candidate1 to
Candidate32
; (decimal) are possible; GWES will examine them sequentially until it finds
; a match.
[HKEY_LOCAL_MACHINE\System\GDI\DisplayCandidates]
 "Candidate5"="Drivers\\BuiltIn\\PCI\\Instance\\SMI"

; @CESYSGEN ENDIF CE_MODULES_PCI

ENDIF ; BSP_DISPLAY_SMI

IF BSP_DISPLAY_SMI
[HKEY_LOCAL_MACHINE\System\GDI\Drivers]
 "Display"="ddi_smi.dll"

;
; SMI driver settings
;
[HKEY_LOCAL_MACHINE\Drivers\Display\SMI]
;; 800x600x16
 "CxScreen"=dword:320
 "CyScreen"=dword:258
 "BPP"=dword:10

ENDIF ; BSP_DISPLAY_SMI
---------------------------------------------------

Am I missing something here? Are these the correct settings for display
driver? I checked the other types of display driver settings in common.reg
and made the similar changes to the platform.reg. Still I get the same
error:

I check the nk.bin file with viewbin.exe and I find the following in the
