 235           On DiskOnChip devices shipped with the INFTL filesystem (Millennium
 236           and 2000 TSOP/Alon), Linux reserves some space at the end of the
 237           device for the Bad Block Table (BBT).  If you have existing INFTL
 238           data on your device (created by non-Linux tools such as M-Systems'
 239           DOS drivers), your data might overlap the area Linux wants to use for
 240           the BBT.  If this is a concern for you, leave this option disabled and
 241           Linux will not write BBT data into this area.
 242           The downside of leaving this option disabled is that if bad blocks
 243           are detected by Linux, they will not be recorded in the BBT, which
 244           could cause future problems.
 245           Once you enable this option, new filesystems (INFTL or others, created
 246           in Linux or other operating systems) will not use the reserved area.
 247           The only reason not to enable this option is to prevent damage to
 248           preexisting filesystems.
 249           Even if you leave this disabled, you can enable BBT writes at module
 250           load time (assuming you build diskonchip as a module) with the module
