Hi, there. I am newbie here. In order to make ISO file, you can use OSCDIMG.EXE with HFSLIP by the source below. Edit the hfslip-1.7.8.cmd. Find the code. IF NOT EXIST HFTOOLS\CDIMAGE.EXE IF NOT EXIST HFTOOLS\MKISOFS.EXE GOTO :EOF Add the code, IF NOT EXIST HFTOOLS\OSCDIMG.EXE before GOTO :EOF. IF NOT EXIST HFTOOLS\CDIMAGE.EXE IF NOT EXIST HFTOOLS\MKISOFS.EXE IF NOT EXIST HFTOOLS\OSCDIMG.EXE GOTO :EOF Find the code. IF EXIST HFTOOLS\CDIMAGE.EXE IF NOT EXIST HFTOOLS\MKISOFS.EXE IF NOT EXIST HFTOOLS\OSCDIMG.EXE SET FORCECDIMAGE=1 Add IF NOT EXIST HFTOOLS\OSCDIMG.EXE before SET FORCECDIMAGE=1 and one line next. IF EXIST HFTOOLS\CDIMAGE.EXE IF NOT EXIST HFTOOLS\MKISOFS.EXE IF NOT EXIST HFTOOLS\OSCDIMG.EXE SET FORCECDIMAGE=1 IF EXIST HFTOOLS\OSCDIMG.EXE IF NOT EXIST HFTOOLS\CDIMAGE.EXE IF NOT EXIST HFTOOLS\MKISOFS.EXE SET USEOSCDIMG=1 Find the code. IF NOT DEFINED CDIMGSW SET CDIMGSW=-h -j1 -m IF NOT DEFINED MKISSW SET MKISSW=-relaxed-filenames -d -D -N -J -no-emul-boot -no-iso-translate -boot-load-size 4 Add the line, IF NOT DEFINED OSCDIMGSW SET OSCDIMGSW=-o -n -h -m. IF NOT DEFINED CDIMGSW SET CDIMGSW=-h -j1 -m IF NOT DEFINED MKISSW SET MKISSW=-relaxed-filenames -d -D -N -J -no-emul-boot -no-iso-translate -boot-load-size 4 IF NOT DEFINED OSCDIMGSW SET OSCDIMGSW=-o -n -h -m Find the code. IF DEFINED FORCECDIMAGE ( HFTOOLS\CDIMAGE.EXE -l"%ISOTITLE%" %CDIMGSW% -bHFTOOLS\%BBIN% %SOURCE% "%TEMPISO%" ) ELSE ( COPY HFTOOLS\BOOT.BIN SOURCESS >NUL HFTOOLS\mkisofs.exe %MKISSW% -b %BBIN% -o "%TEMPISO%" -V "%ISOTITLE%" %SOURCE% DEL/Q/F SOURCESS\BOOT.BIN ) The code should be changed like this. IF DEFINED FORCECDIMAGE ( HFTOOLS\CDIMAGE.EXE -l"%ISOTITLE%" %CDIMGSW% -bHFTOOLS\%BBIN% %SOURCE% "%TEMPISO%" ) ELSE IF DEFINED USEOSCDIMG ( HFTOOLS\OSCDIMG.EXE -l"%ISOTITLE%" -bHFTOOLS\%BBIN% %OSCDIMGSW% %SOURCE% "%TEMPISO%" ) ELSE ( COPY HFTOOLS\BOOT.BIN SOURCESS >NUL HFTOOLS\mkisofs.exe %MKISSW% -b %BBIN% -o "%TEMPISO%" -V "%ISOTITLE%" %SOURCE% DEL/Q/F SOURCESS\BOOT.BIN ) You can use HFANSWER.INI(HFSLIP answer file) with some variables. USEOSCDIMG=1 OSCDIMGSW=-o -n -h -m Thanks.
