0537 DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.
0538 This option allows you to specify a single address at which to probe
0539 for the device, which is useful if you have other devices in that
0540 range which get upset when they are probed.

0542 (Note that on PowerPC, the normal probe will only check at
0543 0xE4000000.)
0544
0545 Normally, you should leave this set to zero, to allow the probe at
0546 the normal addresses.

0553 DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.
0554 This option changes to make it probe between 0xFFFC8000 and
0555 0xFFFEE000. Unless you are using LinuxBIOS, this is unlikely to be
0556 useful to you. Say 'N'.

0561 help
0562 On DiskOnChip devices shipped with the INFTL filesystem (Millennium
0563 and 2000 TSOP/Alon), Linux reserves some space at the end of the
0564 device for the Bad Block Table (BBT). If you have existing INFTL
0565 data on your device (created by non-Linux tools such as M-Systems'
0566 DOS drivers), your data might overlap the area Linux wants to use for
0567 the BBT. If this is a concern for you, leave this option disabled and
0568 Linux will not write BBT data into this area.
0569 The downside of leaving this option disabled is that if bad blocks
0570 are detected by Linux, they will not be recorded in the BBT, which
0571 could cause future problems.
0572 Once you enable this option, new filesystems (INFTL or others, created
0573 in Linux or other operating systems) will not use the reserved area.
0574 The only reason not to enable this option is to prevent damage to
0575 preexisting filesystems.
0576 Even if you leave this disabled, you can enable BBT writes at module
0577 load time (assuming you build diskonchip as a module) with the module
0578 parameter "inftl_bbt_write=1".
