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