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