39 .Nd mount an MS-DOS file system
57 command attaches the MS-DOS filesystem residing on
60 to the global filesystem namespace at the location
63 This command is normally executed by
65 at boot time, but can be used by any user to mount an
66 MS-DOS file system on any directory that they own (provided,
67 of course, that they have appropriate access to the device that
68 contains the file system).
70 The options are as follows:
73 Use the specified mount
77 or one of the MS-DOS filesystem-specific options
82 all of which can be used to affect Windows name translation in the
83 underlying filesystem.
85 Set the owner of the files in the file system to
87 The default owner is the owner of the directory
88 on which the file system is being mounted.
90 Set the group of the files in the file system to
92 The default group is the group of the directory
93 on which the file system is being mounted.
95 Specify the maximum file permissions for files
101 specifies that, by default, the owner should have
102 read, write, and execute permissions for files, but
103 others should only have read and execute permissions.
106 for more information about octal file modes.)
107 Only the nine low-order bits of
113 directory on which the file system is being mounted.
116 ignore and not generate Win'95 long filenames.
118 Force listing and generation of
119 Win'95 long filenames
120 and separate creation/modification/access dates.
128 searches the root directory of the filesystem to
129 be mounted for any existing Win'95 long filenames.
130 If no such entries are found, but short DOS filenames are found,
137 Ignore the special Win'95 directory entries even
138 if deleting or renaming a file.
142 .\"This option causes the filesystem to be interpreted as an Atari-Gemdos
143 .\"filesystem. The differences to the MS-DOS filesystem are minimal and
144 .\"limited to the boot block. This option enforces
147 Specify locale name used for internal uppercase and lowercase conversions
148 for DOS and Win'95 names.
149 By default ISO 8859-1 assumed as local character set.
151 Specify text file with 3 conversion tables:
154 Local character set to Unicode conversion table (upper half) for Win'95 long
155 names, 128 Unicode codes separated by 8 per row.
156 If some code not present in Unicode, use
157 0x003F code ('?') as replacement.
159 DOS to local character set conversion table (upper half) for DOS names,
160 128 character codes separated by 8 per row.
161 Code 0x3F ('?') used for impossible translations.
163 Local character set to DOS conversion table (upper half) for DOS names,
164 128 character codes separated by 8 per row.
165 Some codes have special meaning:
168 character disallowed in DOS file name;
170 character should be replaced by '_' in DOS file name;
172 character should be skipped in DOS file name;
176 By default ISO 8859-1 assumed as local character set.

194 flag could result in damaged filesystems,
195 albeit the damage is in part taken care of by
196 procedures similar to the ones used in Win'95.
199 and earlier versions could not handle cluster sizes larger than 16K.
200 Just mounting an MS-DOS file system could cause corruption to any
202 Cluster sizes larger than 16K are unavoidable for file system sizes
203 larger than 1G, and also occur when filesystems larger than 1G are
204 shrunk to smaller than 1G using FIPS.
