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