534	  This option changes to make it probe between 0xFFFC8000 and
535	  0xFFFEE000.  Unless you are using LinuxBIOS, this is unlikely to be
536	  useful to you.  Say 'N'.

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