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