ISOLINUX does not support discontiguous files, interleaved mode, or
logical block and sector sizes other than 2048. This should normally
not be a problem.

+ISOLINUX is by default built in two versions, one version with extra
+debugging messages enabled. If you are having problems with ISOLINUX,
+I would greatly appreciate if you could try out the debugging version
+(isolinux-debug.bin) and let me know what it reports.
