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