+If a program depends on the correct label and/or serial number for the
+CD-Rom, you can use the following command to extract that information:
+
+      dd if=<your cdrom device> bs=1 skip=32808 count=32
+
+You need read access to the device, so perhaps you have to do it as root.
+Put the resulting string (without trailing blanks) into your
+wine.ini/.winerc file like:
+Label=<the label>
+
+[FIXME: if someone knows how to get the serial number in Linux, please
+        put this information here].
+
+If you have access to a Win32 system and C-compiler, you can compile the
+following program to extract this information:
+
+------------------------- begin volinfo.c ---------------------------
+#include <windows.h>
+#include <stdio.h>
+
+int main(int argc,char **argv[])
+{
+    char  drive, root[]="C:\\", label[1002], fsname[1002];
+    DWORD serial, flags, filenamelen, labellen = 1000, fsnamelen = 1000;
+
+    printf("Drive Serial     Flags      Filename-Length "
+           "Label                 Fsname\n");
+    for (drive = 'C'; drive <= 'Z'; drive++)
+    {
+        root[0] = drive;
+        if (GetVolumeInformationA(root,label,labellen,&serial,
+                                  &filenamelen,&flags,fsname,fsnamelen))
+        {
+            strcat(label,"\""); strcat (fsname,"\"");
+            printf("%c:\\   0x%08lx 0x%08lx %15ld \"%-20s \"%-20s\n",
+                   drive, (long) serial, (long) flags, (long) filenamelen,
+                   label, fsname);
+        }
+    }
+    return 0;
