Problem in the code to choose suitable Kernel

[rajesh.kumar]

During installation of xp, i run bootlogo.cmd to select the suitable kernel to load during windows boot.

i have all the kernels(modified) in system32 dir.

The code works well to identify dual or single core.

Problem is in the 2nd para where it has to detect whether normal or PhysicalAddressExtension kernel.

Can someone guide me in this issue?

Clue is that NUMBER_OF_PROCESSORS is reg_sz (decimal)and PhysicalAddressExtension is reg_dword (hex).

bootlogo.cmd

---------------

FOR /F "tokens=3 delims= " %%A IN (\'REG QUERY "HKLM\SYSTEM\ControlSet001\Control\Session Manager\Environment" /v NUMBER_OF_PROCESSORS\') DO SET NUMBER_OF_PROCESSORS=%%A
if %NUMBER_OF_PROCESSORS%==2 goto DUAL

FOR /F "tokens=3 delims= " %%i IN (\'REG QUERY "HKLM\SYSTEM\ControlSet001\Control\Session Manager\Memory Management" /v PhysicalAddressExtension\') DO SET PhysicalAddressExtension=%%i
if %PhysicalAddressExtension%==0x1 goto SPAE
bootcfg /copy /D "Load using default singleprocessor kernel" /ID 1
bootcfg /RAW "/Kernel=KrnlS.exe /SOS" /A /ID 1
bootcfg /RAW "/SOS" /A /ID 2
goto End

:SPAE
bootcfg /copy /D "Load using default Singleprocessor PAE kernel" /ID 1
bootcfg /RAW "/Kernel=KrnlSpa.exe /SOS" /A /ID 1
bootcfg /RAW "/SOS" /A /ID 2
goto End

:DUAL
FOR /F "tokens=3 delims= " %%i IN (\'REG QUERY "HKLM\SYSTEM\ControlSet001\Control\Session Manager\Memory Management" /v PhysicalAddressExtension\') DO SET PhysicalAddressExtension=%%i
if %PhysicalAddressExtension%==0x1 goto MPAE
bootcfg /copy /D "Load using default multiprocessor/HT kernel" /ID 1
bootcfg /RAW "/Kernel=KrnlM.exe /SOS" /A /ID 1
bootcfg /RAW "/SOS" /A /ID 2
goto End

:MPAE
bootcfg /copy /D "Load using default multiprocessor/HT PAE kernel" /ID 1
bootcfg /RAW "/Kernel=KrnlMpa.exe /SOS" /A /ID 1
bootcfg /RAW "/SOS" /A /ID 2

:End
bootcfg /Timeout 15
bootcfg /Default /ID 1
