| help |
| On DiskOnChip devices shipped with the INFTL filesystem (Millennium |

| device for the Bad Block Table (BBT). If you have existing INFTL |
| data on your device (created by non-Linux tools such as M-Systems' |
| DOS drivers), your data might overlap the area Linux wants to use for |
| the BBT. If this is a concern for you, leave this option disabled and |
| Linux will not write BBT data into this area. |
| The downside of leaving this option disabled is that if bad blocks |
| are detected by Linux, they will not be recorded in the BBT, which |
| could cause future problems. |
| Once you enable this option, new filesystems (INFTL or others, created |
| in Linux or other operating systems) will not use the reserved area. |
| The only reason not to enable this option is to prevent damage to |
| preexisting filesystems. |

| load time (assuming you build diskonchip as a module) with the module |
| parameter "inftl_bbt_write=1". |
