晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。 　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。 　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔 一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。 　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 .

mkdosfs - Make DOS filesystem utilty.


I wrote this, partially to complement the dosfsck utility written by Werner
Almesberger (who graciously gave me some pointers when I asked for some
advice about writing this code), and also to avoid me having to boot DOS
just to create data partitions (I use Linux to back up DOS :-) ).

The code is really derived from Remy Card's mke2fs utility - I used this as a
framework, although all of the filesystem specific stuff was removed and the
DOS stuff inserted.  I believe originally mke2fs was based on Linus' mkfs
code, hence the acknowledgements in the source code.

Neither Remy nor Linus have had any involvement with mkdosfs, so if there are
any bugs they're almost certainly "all my own work".

The code has been available for ftp since 1st September 1993, and I have yet
to receive any bug reports from users.  I don't know of any bugs, but if you
do find a bug or have any constructive comments, please mail me!

The only bug I found with version 0.1 was an obscure fault that could lead
to an invalid (for MS-DOS, not Linux's dos fs) number of sectors used in the
file allocation table(s).

FAT32 support
=============

mkdosfs now can also create filesystems in the new FAT32 format. To do
this, give mkdosfs a "-F 32" option. FAT32 isn't selected
automatically (yet), even if very large clusters are needed with
FAT16. With FAT32 you have two additional options, -R to select the
number of reserved sectors (usually 32), and -b to select the location
of the backup boot sector (default 6). Of course such a backup is
created, as well as the new info sector. On FAT32, the root directory
is always created as a cluster chain. Sorry, there's no switch to
generate an old static root dir.

One bigger bug fix besides FAT32 was to reject filesystems that need a
16 bit FAT to fit all possible clusters, but the bigger FAT needs some
more sectors, so the total number of clusters drop below the border
where MS-DOS expects a 12 bit FAT. So such filesystems would be FAT16,
but interpreted as FAT32 by DOS. The fix is to reduce filesystem size
a bit.
