298 On DiskOnChip devices shipped with the INFTL filesystem (Millennium
299 and 2000 TSOP/Alon), Linux reserves some space at the end of the
300 device for the Bad Block Table (BBT). If you have existing INFTL
301 data on your device (created by non-Linux tools such as M-Systems'
302 DOS drivers), your data might overlap the area Linux wants to use for
303 the BBT. If this is a concern for you, leave this option disabled and
304 Linux will not write BBT data into this area.
305 The downside of leaving this option disabled is that if bad blocks
306 are detected by Linux, they will not be recorded in the BBT, which
307 could cause future problems.
308 Once you enable this option, new filesystems (INFTL or others, created
309 in Linux or other operating systems) will not use the reserved area.
310 The only reason not to enable this option is to prevent damage to
311 preexisting filesystems.
312 Even if you leave this disabled, you can enable BBT writes at module
313 load time (assuming you build diskonchip as a module) with the module
314 parameter "inftl_bbt_write=1".
