Note for Windows 3.1 user : If you have problem for reading/writing floppy, try add in WINIMAGE.INI file the line : UseDpmi=TRUE or UseIoCtl=FALSE UseIoCtl (default : TRUE) say that read/write floppy is done by DOS IOCTL if UseIoCtl=FALSE, WinImage use Int 13h (BIOS), like version 1.0 and 1.11 and say me your configuration. There is another line you can add in WinImage.ini : AutoRetry = TRUE AutoRetry (default = FALSE) say that WinImage do 1 retry when there is a floppy error. NT User can change AutoRetry in Software/WinImage key in registration database (run REGEDT32, and use the HKEY_CURRENT_USER window). UseDpmi and UseIoCtl have only action in WINIMAGE.EXE (win16 version). As I will drop Win16 version in next version, say me if you have problem with Win32 (winimant.Exe) version under Windows 3.1 + Win32s.
