539	help
540	  On DiskOnChip devices shipped with the INFTL filesystem (Millennium
541	  and 2000 TSOP/Alon), Linux reserves some space at the end of the
542	  device for the Bad Block Table (BBT).  If you have existing INFTL
543	  data on your device (created by non-Linux tools such as M-Systems'
544	  DOS drivers), your data might overlap the area Linux wants to use for
545	  the BBT.  If this is a concern for you, leave this option disabled and
546	  Linux will not write BBT data into this area.
547	  The downside of leaving this option disabled is that if bad blocks
548	  are detected by Linux, they will not be recorded in the BBT, which
549	  could cause future problems.
550	  Once you enable this option, new filesystems (INFTL or others, created
551	  in Linux or other operating systems) will not use the reserved area.
552	  The only reason not to enable this option is to prevent damage to
553	  preexisting filesystems.
554	  Even if you leave this disabled, you can enable BBT writes at module
555	  load time (assuming you build diskonchip as a module) with the module
556	  parameter "inftl_bbt_write=1".
