 260           On DiskOnChip devices shipped with the INFTL filesystem (Millennium
 261           and 2000 TSOP/Alon), Linux reserves some space at the end of the
 262           device for the Bad Block Table (BBT).  If you have existing INFTL
 263           data on your device (created by non-Linux tools such as M-Systems'
 264           DOS drivers), your data might overlap the area Linux wants to use for
 265           the BBT.  If this is a concern for you, leave this option disabled and
 266           Linux will not write BBT data into this area.
 267           The downside of leaving this option disabled is that if bad blocks
 268           are detected by Linux, they will not be recorded in the BBT, which
 269           could cause future problems.
 270           Once you enable this option, new filesystems (INFTL or others, created
 271           in Linux or other operating systems) will not use the reserved area.
 272           The only reason not to enable this option is to prevent damage to
 273           preexisting filesystems.
 274           Even if you leave this disabled, you can enable BBT writes at module
