271 help
272 On DiskOnChip devices shipped with the INFTL filesystem (Millennium
273 and 2000 TSOP/Alon), Linux reserves some space at the end of the
274 device for the Bad Block Table (BBT). If you have existing INFTL
275 data on your device (created by non-Linux tools such as M-Systems'
276 DOS drivers), your data might overlap the area Linux wants to use for
277 the BBT. If this is a concern for you, leave this option disabled and
278 Linux will not write BBT data into this area.
279 The downside of leaving this option disabled is that if bad blocks
280 are detected by Linux, they will not be recorded in the BBT, which
281 could cause future problems.
282 Once you enable this option, new filesystems (INFTL or others, created
283 in Linux or other operating systems) will not use the reserved area.
284 The only reason not to enable this option is to prevent damage to
285 preexisting filesystems.
286 Even if you leave this disabled, you can enable BBT writes at module
287 load time (assuming you build diskonchip as a module) with the module
288 parameter "inftl_bbt_write=1".
