IIIInnnnttttrrrroooodddduuuuccccttttiiiioooonnnn Mtools is a public domain collection of tools to allow Unix systems to manipulate MS-DOS files: read, write, and move around files on an MS-DOS filesystem (typically a floppy disk). Where reasonable, each program attempts to emulate the MS-DOS equivalent command. However, unnecessary restrictions and oddities of DOS are not emulated. For instance, it is possible to move subdirectories from one subdirectory to another. Mtools is sufficient to give access to MS-DOS filesystems. For instance, commands such as mdir a: work on the a: floppy without any preliminary mounting or initialization (assuming the default `/etc/mtools.conf' works on your machine). With mtools, one can change floppies too without unmounting and mounting. WWWWhhhheeeerrrreeee ttttoooo ggggeeeetttt mmmmttttoooooooollllssss Mtools can be found at the following places (and their mirrors): hhhhttttttttpppp::::////////mmmmttttoooooooollllssss....lllliiiinnnnuuuuxxxx....lllluuuu////mmmmttttoooooooollllssss----3333....9999....1111....ttttaaaarrrr....ggggzzzz ffffttttpppp::::////////wwwwwwwwwwww....ttttuuuuxxxx....oooorrrrgggg////ppppuuuubbbb////kkkknnnnaaaaffffffff////mmmmttttoooooooollllssss////mmmmttttoooooooollllssss----3333....9999....1111....ttttaaaarrrr....ggggzzzz ffffttttpppp::::////////ssssuuuunnnnssssiiiitttteeee....uuuunnnncccc....eeeedddduuuu////ppppuuuubbbb////LLLLiiiinnnnuuuuxxxx////uuuuttttiiiillllssss////ddddiiiisssskkkk----mmmmaaaannnnaaaaggggeeeemmmmeeeennnntttt////mmmmttttoooooooollllssss----3333....9999....1111....ttttaaaarrrr....ggggzzzz Before reporting a bug, make sure that it has not yet been fixed in the Alpha patches which can be found at: hhhhttttttttpppp::::////////mmmmttttoooooooollllssss....lllliiiinnnnuuuuxxxx....lllluuuu//// ffffttttpppp::::////////wwwwwwwwwwww....ttttuuuuxxxx....oooorrrrgggg////ppppuuuubbbb////kkkknnnnaaaaffffffff////mmmmttttoooooooollllssss These patches are named mtools-_v_e_r_s_i_o_n-_d_d_m_m.taz, where version stands for the base version, _d_d for the day and _m_m for the month.

Only the filename part is mandatory, the drive letter and the subdirectory are optional. Filenames without a drive letter refer to Unix files. Subdirectory names can use either the '/' or '\' separator. The use of the '\' separator or wildcards requires the names to be enclosed in quotes to protect them from the shell. However, wildcards in Unix filenames should not be enclosed in quotes, because here we wwwwaaaannnntttt the shell to expand them. The regular expression "pattern matching" routines follow the Unix-style rules. For example, `*' matches all MS-DOS files in lieu of `*.*'. The archive, hidden, read-only and system attribute bits are ignored during pattern matching. All options use the - (minus) as their first character, not / as you'd expect in MS-DOS. Most mtools commands allow multiple filename parameters, which doesn't follow MS-DOS conventions, but which is more user-friendly. Most mtools commands allow options that instruct them how to handle file name clashes. See section name clashes, for more details on these. All commands accept the -V flags which prints the version, and most accept the -v flag, which switches on verbose mode. In verbose mode, these commands print out the name of the MS-DOS files upon which they act, unless stated otherwise. See section Commands, for a description of the options which are specific to each command. DDDDrrrriiiivvvveeee lllleeeetttttttteeeerrrrssss The meaning of the drive letters depends on the target architectures. However, on most target architectures, drive A is the first floppy drive, drive B is the second floppy drive (if available), drive J is a Jaz drive (if available), and drive Z is a Zip drive (if available). On those systems where the device name is derived from the SCSI id, the Jaz drive is assumed to be at Scsi target 4, and the Zip at Scsi target 5 (factory default settings). On Linux, both drives are assumed to be the second drive on the Scsi bus (/dev/sdb). The default settings can be changes using a configuration file (See section Configuration). CCCCuuuurrrrrrrreeeennnntttt wwwwoooorrrrkkkkiiiinnnngggg ddddiiiirrrreeeeccccttttoooorrrryyyy The mcd command (`mcd') is used to establish the device and the current working directory (relative to the MS-DOS filesystem), otherwise the default is assumed to be A:/.

VVVVFFFFAAAATTTT----ssssttttyyyylllleeee lllloooonnnngggg ffffiiiilllleeee nnnnaaaammmmeeeessss This version of mtools supports VFAT style long filenames. If a Unix filename is too long to fit in a short DOS name, it is stored as a VFAT long name, and a companion short name is generated. This short name is what you see when you examine the disk with a pre-7.0 version of DOS. The following table shows some examples of short names: LLLLoooonnnngggg nnnnaaaammmmeeee MMMMSSSS----DDDDOOOOSSSS nnnnaaaammmmeeee RRRReeeeaaaassssoooonnnn ffffoooorrrr tttthhhheeee cccchhhhaaaannnnggggeeee ------------------------------------ ---------------------------------------- ------------------------------------------------------------------------------------ tttthhhhiiiissssiiiissssaaaatttteeeesssstttt TTTTHHHHIIIISSSSIIIISSSS~~~~1111 ffffiiiilllleeeennnnaaaammmmeeee ttttoooooooo lllloooonnnngggg aaaallllaaaaiiiinnnn....kkkknnnnaaaaffffffff AAAALLLLAAAAIIIINNNN~~~~1111....KKKKNNNNAAAA eeeexxxxtttteeeennnnssssiiiioooonnnn ttttoooooooo lllloooonnnngggg pppprrrrnnnn....ttttxxxxtttt PPPPRRRRNNNN~~~~1111....TTTTXXXXTTTT PPPPRRRRNNNN iiiissss aaaa ddddeeeevvvviiiicccceeee nnnnaaaammmmeeee ....aaaabbbbcccc AAAABBBBCCCC~~~~1111 nnnnuuuullllllll ffffiiiilllleeeennnnaaaammmmeeee hhhhooootttt++++ccccoooolllldddd HHHHOOOOTTTT____CCCCOOOO~~~~1111 iiiilllllllleeeeggggaaaallll cccchhhhaaaarrrraaaacccctttteeeerrrr As you see, the following transformations happen to derive a short name: * Illegal characters are replaced by underscores. The illegal characters are ;+=[]',\"*\\<>/?:|. * Extra dots, which cannot be interpreted as a main name/extension separator are removed * A ~_n number is generated, * The name is shortened so as to fit in the 8+3 limitation The initial Unix-style file name (whether long or short) is also called the _p_r_i_m_a_r_y name, and the derived short name is also called the _s_e_c_o_n_d_a_r_y name. Example: mmmmccccooooppppyyyy ////eeeettttcccc////mmmmoooottttdddd aaaa::::RRRReeeeaaaallllllllyyyylllloooonnnnggggnnnnaaaammmmeeee Mtools creates a VFAT entry for Reallylongname, and uses REALLYLO as a short name. Reallylongname is the primary name, and REALLYLO is the secondary name. mmmmccccooooppppyyyy ////eeeettttcccc////mmmmoooottttdddd aaaa::::mmmmoooottttdddd Motd fits into the DOS filename limits. Mtools doesn't need to derivate another name. Motd is the primary name, and there is no secondary name.

Although VFAT is much more flexible than FAT, there are still names that are not acceptable, even in VFAT. There are still some illegal characters left (\"*\\<>/?:|), and device names are still reserved.

This may happen for all commands which create new directory entries, such as mcopy, mmd, mren, mmove, mwrite and mread. When a name clash happens, mtools asks you what it should do. It offers several choices: overwrite Overwrites the existing file. It is not possible to overwrite a directory with a file. rename Renames the newly created file. Mtools prompts for the new filename autorename Renames the newly created file. Mtools chooses a name by itself, without prompting skip Gives up on this file, and moves on to the next (if any) To chose one of these actions, type its first letter at the prompt. If you use a lower case letter, the action only applies for this file only, if you use an upper case letter, the action applies to all files, and you won't be prompted again. Page 4 (printed 7/15/98) mmmmttttoooooooollllssss....1111((((3333)))) MMMMTTTTOOOOOOOOLLLLSSSS ((((11114444mmmmaaaarrrr1111999999997777)))) mmmmttttoooooooollllssss....1111((((3333)))) You may also chose actions (for all files) on the command line, when invoking mtools: -o Overwrites primary names by default. -O Overwrites secondary names by default. -r Renames primary name by default. -R Renames secondary name by default. -a Autorenames primary name by default. -A Autorenames secondary name by default. -s Skip primary name by default. -S Skip secondary name by default. -m Ask user what to do with primary name. -M Ask user what to do with secondary name. Note that for command line switches lower/upper differentiates between primary/secondary name whereas for interactive choices, lower/upper differentiates between just-this-time/always. The primary name is the name as displayed in Windows 95 or Windows NT: i.e. the long name if it exists, and the short name otherwise. The secondary name is the "hidden" name, i.e. the short name if a long name exists. By default, the user is prompted if the primary name clashes, and the secondary name is autorenamed. If a name clash occurs in a Unix directory, mtools only asks whether to overwrite the file, or to skip it. CCCCaaaasssseeee sssseeeennnnssssiiiittttiiiivvvviiiittttyyyy ooooffff tttthhhheeee VVVVFFFFAAAATTTT ffffiiiilllleeeessssyyyysssstttteeeemmmm The VFAT filesystem is able to remember the case of the filenames. However, filenames which differ only in case are not allowed to coexist in the same directory. For example if you store a file called LongFileName on a VFAT filesystem, mdir shows this file as LongFileName, and not as Longfilename. However, if you then try to add LongFilename to the same directory, it is refused, because case is ignored for clash checks. The VFAT filesystem allows to store the case of a filename in the attribute byte, if all letters of the filename are the same case, and if all letters of the extension are the Page 5 (printed 7/15/98) mmmmttttoooooooollllssss....1111((((3333)))) MMMMTTTTOOOOOOOOLLLLSSSS ((((11114444mmmmaaaarrrr1111999999997777)))) mmmmttttoooooooollllssss....1111((((3333)))) same case too. Mtools uses this information when displaying the files, and also to generate the Unix filename when mcopying to a Unix directory. This may have unexpected results when applied to files written using an pre-7.0 version of DOS: Indeed, the old style filenames map to all upper case. This is different from the behavior of the old version of mtools which used to generate lower case Unix filenames. hhhhiiiigggghhhh ccccaaaappppaaaacccciiiittttyyyy ffffoooorrrrmmmmaaaattttssss Mtools supports a number of formats which allow to store more data on disk as usual. Due to different operating system abilities, these formats are not supported on all OS'es. Mtools recognizes these formats transparently where supported. In order to format these disks, you need to use an operating system specific tool. For Linux, suitable floppy tools can be found in the fdutils package at the following locations~: ftp://www.tux.org/pub/knaff/fdutils/. ftp://sunsite.unc.edu/pub/Linux/utils/disk-management/fdutils-* See the manpages included in that package for further detail: Use superformat to format all formats except XDF, and use xdfcopy to format XDF. MMMMoooorrrreeee sssseeeeccccttttoooorrrrssss The oldest method of fitting more data on a disk is to use more sectors and more cylinders. Although the standard format uses 80 cylinders and 18 sectors (on a 3 1/2 high density disk), it is possible to use up to 83 cylinders (on most drives) and up to 21 sectors. This method allows to store up to 1743K on a 3 1/2 HD disk. However, 21 sector disks are twice as slow as the standard 18 sector disks because the sectors are packed so close together that we need to interleave them. This problem doesn't exist for 20 sector formats. These formats are supported by numerous DOS shareware utilities such as fdformat and vgacopy. In his infinite hybris, Bill Gate$ believed that he invented this, and called it `DMF disks', or `Windows formatted disks'. But in reality, it has already existed years before! Mtools supports these formats on Linux, on SunOs and on the DELL Unix PC. BBBBiiiiggggggggeeeerrrr sssseeeeccccttttoooorrrrssss By using bigger sectors it is possible to go beyond the capacity which can be obtained by the standard 512-byte Page 6 (printed 7/15/98) mmmmttttoooooooollllssss....1111((((3333)))) MMMMTTTTOOOOOOOOLLLLSSSS ((((11114444mmmmaaaarrrr1111999999997777)))) mmmmttttoooooooollllssss....1111((((3333)))) sectors. This is because of the sector header. The sector header has the same size, regardless of how many data bytes are in the sector. Thus, we save some space by using _f_e_w_e_r, but bigger sectors. For example, 1 sector of 4K only takes up header space once, whereas 8 sectors of 512 bytes have also 8 headers, for the same amount of useful data. This method allows to store up to 1992K on a 3 1/2 HD disk. Mtools supports these formats only on Linux. 2222mmmm The 2m format was originally invented by Ciriaco Garcia de Celis. It also uses bigger sectors than usual in order to fit more data on the disk. However, it uses the standard format (18 sectors of 512 bytes each) on the first cylinder, in order to make these disks easyer to handle by DOS. Indeed this method allows to have a standard sized bootsector, which contains a description of how the rest of the disk should be read. However, the drawback of this is that the first cylinder can hold less data than the others. Unfortunately, DOS can only handle disks where each track contains the same amount of data. Thus 2m hides the fact that the first track contains less data by using a _s_h_a_d_o_w _F_A_T. (Usually, DOS stores the FAT in two identical copies, for additional safety. XDF stores only one copy, and it tells DOS that it stores two. Thus the same that would be taken up by the second FAT copy is saved.) This also means that your should nnnneeeevvvveeeerrrr uuuusssseeee aaaa 2222mmmm ddddiiiisssskkkk ttttoooo ssssttttoooorrrreeee aaaannnnyyyytttthhhhiiiinnnngggg eeeellllsssseeee tttthhhhaaaannnn aaaa DDDDOOOOSSSS ffffssss. Mtools supports these format only on Linux. XXXXDDDDFFFF XDF is a high capacity format used by OS/2. It can hold 1840 K per disk. That's lower than the best 2m formats, but its main advantage is that it is fast: 600 milliseconds per track. That's faster than the 21 sector format, and almost as fast as the standard 18 sector format. In order to access these disks, make sure mtools has been compiled with XDF support, and set the use_xdf variable for the drive in the configuration file. See section Compiling mtools and `misc variables', for details on how to do this. Fast XDF access is only available for Linux kernels which are more recent than 1.1.34. Mtools supports this format only on Linux. CCCCaaaauuuuttttiiiioooonnnn //// AAAAtttttttteeeennnnttttiiiioooonnnn ddddiiiissssttttrrrriiiibbbbuuuuttttoooorrrrssss: If mtools is compiled on a Linux kernel more recent than 1.3.34, it won't run on an older kernel. However, if it has been compiled on an older Page 7 (printed 7/15/98) mmmmttttoooooooollllssss....1111((((3333)))) MMMMTTTTOOOOOOOOLLLLSSSS ((((11114444mmmmaaaarrrr1111999999997777)))) mmmmttttoooooooollllssss....1111((((3333)))) kernel, it still runs on a newer kernel, except that XDF access is slower. It is recommended that distribution authors only include mtools binaries compiled on kernels older than 1.3.34 until 2.0 comes out. When 2.0 will be out, mtools binaries compiled on newer kernels may (and should) be distributed. Mtools binaries compiled on kernels older than 1.3.34 won't run on any 2.1 kernel or later. EEEExxxxiiiitttt ccccooooddddeeeessss All the Mtools commands return 0 on success, 1 on utter failure, or 2 on partial failure. All the Mtools commands perform a few sanity checks before going ahead, to make sure that the disk is indeed an MS-DOS disk (as opposed to, say an ext2 or minix disk). These checks may reject partially corrupted disks, which might otherwise still be readable. To avoid these checks, set the MTOOLS_SKIP_CHECK environmental variable or the corresponding configuration file variable (see section global variables) BBBBuuuuggggssss An unfortunate side effect of not guessing the proper device (when multiple disk capacities are supported) is an occasional error message from the device driver. These can be safely ignored. The fat checking code chokes on 1.72 Mb disks mformatted with pre-2.0.7 mtools. Set the environmental variable MTOOLS_FAT_COMPATIBILITY (or the corresponding configuration file variable, `global variables') to bypass the fat checking.

The configuration files are called `/usr/freeware/etc/mtools.conf' and `~/.mtoolsrc'. If the environmental variable MTOOLSRC is set, its contents is used as the filename for a third configuration file. These configuration files describe the following items: * Global configuration flags and variables * Per drive flags and variables * Character translation tables LLLLooooccccaaaattttiiiioooonnnn ooooffff tttthhhheeee ccccoooonnnnffffiiiigggguuuurrrraaaattttiiiioooonnnn ffffiiiilllleeeessss `/usr/freeware/etc/mtools.conf' is the system-wide configuration file, and `~/.mtoolsrc' is the user's private configuration file. On some systems, the system-wide configuration file is Page 8 (printed 7/15/98) mmmmttttoooooooollllssss....1111((((3333)))) MMMMTTTTOOOOOOOOLLLLSSSS ((((11114444mmmmaaaarrrr1111999999997777)))) mmmmttttoooooooollllssss....1111((((3333)))) called `/etc/defaults/mtools.conf' instead. GGGGeeeennnneeeerrrraaaallll ccccoooonnnnffffiiiigggguuuurrrraaaattttiiiioooonnnn ffffiiiilllleeee ssssyyyynnnnttttaaaaxxxx The configuration files is made up of sections. Each section starts with a keyword identifying the section followed by a colon. Then follow variable assignments and flags. Variable assignments take the following form: name=value Flags are lone keywords without an equal sign and value following them. A section either ends at the end of the file or where the next section begins. Lines starting with a hash (#) are comments. Newline characters are equivalent to whitespace (except where ending a comment). The configuration file is case insensitive, except for item enclosed in quotes (such as filenames). DDDDeeeeffffaaaauuuulllltttt vvvvaaaalllluuuueeeessss For most platforms, mtools contains reasonable compiled-in defaults for physical floppy drives. Thus, you usually don't need to bother with the configuration file, if all you want to do with mtools is to access your floppy drives. On the other hand, the configuration file is needed if you also want to use mtools to access your hard disk partitions and dosemu image files. GGGGlllloooobbbbaaaallll vvvvaaaarrrriiiiaaaabbbblllleeeessss Global flags may be set to 1 or to 0. The following global flags are recognized: MTOOLS_SKIP_CHECK If this is set to 1, mtools skips most of its sanity checks. This is needed to read some Atari disks which have been made with the earlier ROMs, and which would not be recognized otherwise. MTOOLS_FAT_COMPATIBILITY If this is set to 1, mtools skips the fat size checks. Some disks have a bigger FAT than they really need to. These are rejected if this option is not set. MTOOLS_LOWER_CASE If this is set to 1, mtools displays all-upper-case short filenames as lowercase. This has been done to allow a behavior which is consistent with older versions of mtools which didn't know about the case bits. MTOOLS_NO_VFAT If this is set to 1, mtools won't generate VFAT entries for filenames which are mixed-case, but otherwise legal Page 9 (printed 7/15/98) mmmmttttoooooooollllssss....1111((((3333)))) MMMMTTTTOOOOOOOOLLLLSSSS ((((11114444mmmmaaaarrrr1111999999997777)))) mmmmttttoooooooollllssss....1111((((3333)))) dos filenames. This is useful when working with DOS versions which can't grok VFAT longnames, such as FreeDos. MTOOLS_DOTTED_DIR In a wide directory, prints the short name with a dot instead of spaces separating the basename and the extension. MTOOLS_NAME_NUMERIC_TAIL If this is set to one (default), generate numeric tails for all long names (~1). If set to zero, only generate numeric tails if otherwise a clash would have happened. MTOOLS_TWENTY_FOUR_HOUR_CLOCK If 1, uses the European notation for times (twenty four hour clock), else uses the UK/US notation (am/pm) Example: Inserting the following line into your configuration file instructs mtools to skip the sanity checks: MMMMTTTTOOOOOOOOLLLLSSSS____SSSSKKKKIIIIPPPP____CCCCHHHHEEEECCCCKKKK====1111 Global variables may also be set via the environment: eeeexxxxppppoooorrrrtttt MMMMTTTTOOOOOOOOLLLLSSSS____SSSSKKKKIIIIPPPP____CCCCHHHHEEEECCCCKKKK====1111 Global string variables may be set to any value: MTOOLS_DATE_STRING The format used for printing dates of files.

Its has three purposes: formatting The geometry information is written into the boot sector of the newly made disk. However, you may also describe the geometry information on the command line. See section mformat for details. filtering On some Unices there are device nodes which only support one physical geometry. For instance, you might need a different node to access a disk as high density or as low density. The geometry is compared to the actual geometry stored on the boot sector to make sure that this device node is able to correctly read the disk. If the geometry doesn't match, this drive entry fails, and the next drive entry bearing the same drive letter is tried. See section multiple descriptions for more details on supplying several descriptions for one drive letter. If no geometry information is supplied in the configuration file, all disks are accepted. On Linux (and on Sparc) there exist device nodes with configurable geometry (`/dev/fd0', `/dev/fd1' etc), and thus filtering is not needed (and ignored) for disk drives. (Mtools still does do filtering on plain files (disk images) in Linux: this is mainly intended for test purposes, as I don't have access to a Unix which would actually need filtering). If you do not need filtering, but want still a default geometry for mformatting, you may switch off filtering using the mformat_only flag. initial geometry On devices that support it (usually floppy devices), the geometry information is also used to set the initial geometry. This initial geometry is applied while reading the boot sector, which contains the real geometry. If no geometry information is supplied in the configuration file, or if the mformat_only flag is supplied, no initial configuration is done. On Linux, initial geometry is not really needed, as the configurable devices are able to auto-detect the disk type accurately enough (for most common formats) to read the boot sector. Wrong geometry information may lead to very bizarre errors.

The following geometry related variables are available: cylinders tracks The number of cylinders. (cylinders is the preferred form, tracks is considered obsolete) heads The number of heads (sides). sectors The number of sectors per track.

Depending to their type, these variables can be set to a string (file, precmd) or an integer (all others) file The name of the file or device holding the disk image. This is mandatory. The file name should be enclosed in quotes. partition Tells mtools to treat the drive as a partitioned device, and to use the given partition. Only primary partitions are accessible using this method, and they are numbered from 1 to 4. For logical partitions, use the more general offset variable. The partition variable is intended for removable media such as Syquests, ZIP drives, and magneto-optical disks. Although traditional DOS sees Syquests and magneto- optical disks as `giant floppy disks' which are unpartitioned, OS/2 and Windows NT treat them like hard disks, i.e. partioned devices. The partition flag is also useful DOSEMU hdimages. It is not recommended for hard disks for which direct access to partitions is available through mounting. offset Describes where in the file the MS-DOS filesystem starts. This is useful for logical partitions in DOSEMU hdimages, and for ATARI ram disks. By default, this is zero, meaning that the filesystem starts right at the beginning of the device or file. fat_bits The number of FAT bits. This may be 12 or 16. This is very rarely needed, as it can almost always be deduced from information in the boot sector. On the contrary, describing the number of fat bits may actually be harmful if you get it wrong. You should only use it if Page 13 (printed 7/15/98) mmmmttttoooooooollllssss....1111((((3333)))) MMMMTTTTOOOOOOOOLLLLSSSS ((((11114444mmmmaaaarrrr1111999999997777)))) mmmmttttoooooooollllssss....1111((((3333)))) mtools gets the autodetected number of fat bits wrong, or if you want to mformat a disk with a weird number of fat bits. precmd On some variants of Solaris, it is necessary to call 'volcheck -v' before opening a floppy device, in order for the system to notice that there is indeed a disk in the drive. precmd="volcheck -v" in the drive clause establishes the desired behavior. blocksize This parameter represents a default block size to be always used on this device. All I/O is done with multiples of this block size, independantly of the sector size registered in the filesystem's boot sector. This is useful for character devices whose sector size is not 512, such as for example CD Rom drives on Solaris. Only the file variable is mandatory. The other parameters may be left out. In that case a default value or an autodetected value is used. GGGGeeeennnneeeerrrraaaallll PPPPuuuurrrrppppoooosssseeee DDDDrrrriiiivvvveeee FFFFllllaaaaggggssss A flag can either be set to 1 (enabled) or 0 (disabled). If the value is ommitted, it is enabled. For example, scsi is equivalent to scsi=1 nolock Instruct mtools to not use locking on this drive. This is needed on systems with buggy locking semantics. However, enabling this makes operation less safe in cases where several users may access the same drive at the same time. scsi When set to 1, this option tells mtools to use raw SCSI I/O instead of the standard read/write calls to access the device. Currently, this is supported on HP/UX, Solaris and SunOs. This is needed because on some architectures, such as SunOs or Solaris, PC media can't be accessed using the read and write syscalls, because the OS expects them to contain a Sun specific "disk label". As raw Scsi access always uses the whole device, you need to specify the "partition" flag in addition On some architectures, such as Solaris, mtools needs Page 14 (printed 7/15/98) mmmmttttoooooooollllssss....1111((((3333)))) MMMMTTTTOOOOOOOOLLLLSSSS ((((11114444mmmmaaaarrrr1111999999997777)))) mmmmttttoooooooollllssss....1111((((3333)))) root privileges to be able to use the scsi option. Thus mtools should be installed set uid root on Solaris if you want to access Zip/Jaz drives. Thus, if the scsi flag is given, privileged is automatically implied, unless explicitly disabled by privileged=0 Mtools uses its root privileges to open the device, and to issue the actual SCSI I/O calls. Moreover, root privileges are only used for drives described in a system-wide configuration file such as `/usr/freeware/etc/mtools.conf', and not for those described in `~/.mtoolsrc' or `$MTOOLSRC'. privileged When set to 1, this instructs mtools to use its set-uid and set-gid privileges for opening the given drive. This option is only valid for drives described in the system-wide configuration files (such as `/usr/freeware/etc/mtools.conf', not `~/.mtoolsrc' or `$MTOOLSRC'). Obviously, this option is also a no op if mtools is not installed setuid or setgid. This option is implied by 'scsi=1', but again only for drives defined in system-wide configuration files. Privileged may also be set explicitely to 0, in order to tell mtools not to use its privileges for a given drive even if scsi=1 is set. Mtools only needs to be installed setuid if you use the privileged or scsi drive variables. If you do not use these options, mtools works perfectly well even when not installed setuid root. vold Instructs mtools to interpret the device name as a vold identifier rather than as a filename. The vold identifier is translated into a real filename using the media_findname() and media_oldaliases() functions of the volmgt library. This flag is only available if you configured mtools with the --enable-new-vold option before compilation. use_xdf If this is set to a non-zero value, mtools also tries to access this disk as an XDF disk. XDF is a high capacity format used by OS/2. This is off by default. See section XDF for more details. mformat_only Tells mtools to use the geometry for this drive only for mformatting and not for filtering.

In that case, the descriptions are tried in order until one is found that fits. Descriptions may fail for several reasons: 1. because the geometry is not appropriate, 2. because there is no disk in the drive, 3. or because of other problems. Multiple definitions are useful when using physical devices which are only able to support one single disk geometry. Example: ddddrrrriiiivvvveeee aaaa:::: ffffiiiilllleeee====""""////ddddeeeevvvv////ffffdddd0000HHHH1111444444440000"""" 1111....44444444mmmm ddddrrrriiiivvvveeee aaaa:::: ffffiiiilllleeee====""""////ddddeeeevvvv////ffffdddd0000HHHH777722220000"""" 777722220000kkkk This instructs mtools to use /dev/fd0H1440 for 1.44m (high density) disks and /dev/fd0H720 for 720k (double density) disks. On Linux, this feature is not really needed, as the /dev/fd0 device is able to handle any geometry. You may also use multiple drive descriptions to access both of your physical drives through one drive letter: ddddrrrriiiivvvveeee zzzz:::: ffffiiiilllleeee====""""////ddddeeeevvvv////ffffdddd0000"""" ddddrrrriiiivvvveeee zzzz:::: ffffiiiilllleeee====""""////ddddeeeevvvv////ffffdddd1111"""" With this description, mdir z: accesses your first physical drive if it contains a disk. If the first drive doesn't contain a disk, mtools checks the second drive. When using multiple configuration files, drive descriptions in the files parsed last override descriptions for the same drive in earlier files. In order to avoid this, use the drive+ or +drive keywords instead of drive. The first adds a description to the end of the list (i.e. it will be tried last), and the first adds it to the start of the list.

To make matters worse, there are several translation tables available depending on the country where you are. The appearance of the characters is defined using code pages. These code pages aren't the same for all countries. For instance, some code pages don't contain upper case accented characters. On the other hand, some code pages contain characters which don't exist in Unix, such as certain line-drawing characters or accented consonants used by some Eastern European countries. This affects two things, relating to filenames: upper case characters In short names, only upper case characters are allowed. This also holds for accented characters. For instance, in a code page which doesn't contain accented uppercase characters, the accented lowercase characters get transformed into their unaccented counterparts. long file names Micro$oft has finally come to their senses and uses a more standard mapping for the long file names. They use Unicode, which is basically a 32 bit version of ASCII. Its first 256 characters are identical to Unix ASCII. Thus, the code page also affects the correspondence between the codes used in long names and those used in short names Mtools considers the filenames entered on the command line as having the Unix mapping, and translates the characters to get short names. By default, code page 850 is used with the Swiss uppercase/lowercase mapping. I chose this code page, because its set of existing characters most closely matches Unix's. Moreover, this code page covers most characters in use in the USA, Australia and Western Europe. However, it is still possible to chose a different mapping. There are two methods: the country variable and explicit tables. CCCCoooonnnnffffiiiigggguuuurrrraaaattttiiiioooonnnn uuuussssiiiinnnngggg CCCCoooouuuunnnnttttrrrryyyy The COUNTRY variable is recommended for people which also have access to MS-DOS system files and documentation. If you don't have access to these, I'd suggest you'd rather use explicit tables instead. Syntax: COUNTRY="_c_o_u_n_t_r_y[,[_c_o_d_e_p_a_g_e], _c_o_u_n_t_r_y-_f_i_l_e]" This tells mtools to use a Unix-to-DOS translation table which matches _c_o_d_e_p_a_g_e and an lowercase-to-uppercase table Page 17 (printed 7/15/98) mmmmttttoooooooollllssss....1111((((3333)))) MMMMTTTTOOOOOOOOLLLLSSSS ((((11114444mmmmaaaarrrr1111999999997777)))) mmmmttttoooooooollllssss....1111((((3333)))) for _c_o_u_n_t_r_y and to use the _c_o_u_n_t_r_y-_f_i_l_e file to get the lowercase-to-uppercase table. The country code is most often the telephone prefix of the country. Refer to the DOS help page on "country" for more details. The _c_o_d_e_p_a_g_e and the _c_o_u_n_t_r_y-_f_i_l_e parameters are optional. Please don't type in the square brackets, they are only there to say which parameters are optional. The _c_o_u_n_t_r_y-_f_i_l_e file is supplied with MS-DOS, and is usually called `COUNTRY.SYS', and stored in the `C:\DOS' directory. In most cases you don't need it, as the most common translation tables are compiled into mtools. So, don't worry if you run a Unix-only box which lacks this file. If _c_o_d_e_p_a_g_e is not given, a per country default code page is used. If the _c_o_u_n_t_r_y-_f_i_l_e parameter isn't given, compiled-in defaults are used for the lowercase-to-uppercase table. This is useful for other Unices than Linux, which may have no `COUNTRY.SYS' file available online. The Unix-to-DOS are not contained in the `COUNTRY.SYS' file, and thus mtools always uses compiled-in defaults for those. Thus, only a limited amount of code pages are supported. If your preferred code page is missing, or if you know the name of the Windows 95 file which contains this mapping, could you please drop me a line at alain@linux.lu. The COUNTRY variable can also be set using the environment.

A lower-to-upper table starts with the fucase keyword, followed by a colon, and 128 hexadecimal numbers. The tables only show the translations for characters whose codes is greater than 128, because translation for lower codes is trivial.

Each floppyd is associated with an X server. When a remote client attempts to connect to floppyd, it sends floppyd the X authority record corresponding to floppyd's X server. Floppyd in turn then tries to open up a connection to the X server in order to verify the authenticity of the xauth record.

The source and target can be either MS-DOS or Unix files. The use of a drive letter designation on the MS-DOS files, 'a:' for example, determines the direction of the transfer. A missing drive designation implies a Unix file whose path starts in the current directory. If a source drive letter is specified with no attached file name (e.g. mcopy a: .), all files are copied from that drive. If only a single, MS-DOS source parameter is provided (e.g. "mcopy a:foo.exe"), an implied destination of the current directory (`.') is assumed. A filename of `-' means standard input or standard output, depending on its position on the command line. Mcopy accepts the following command line options: b Batch mode. Optimized for huge recursive copies, but less secure if a crash happens during the copy. / Recursive copy. Also copies directories and their contents p Preserves the attributes of the copied files Q When mcopying multiple files, quits as soon as one copy fails (for example due to lacking storage space on the target disk) t Text file transfer.

With this option, mdir prints the filenames across the page without displaying the file size or creation date. a Also list hidden files. f Fast. Do not try to find out free space. On larger disks, finding out the amount of free space takes up some non trivial amount of time, as the whole FAT must be read in and scanned. The -f flag bypasses this step.

This command only works on drives whose partition variable is set. mpartition -p _d_r_i_v_e mpartition -r _d_r_i_v_e mpartition -I _d_r_i_v_e mpartition -a _d_r_i_v_e mpartition -d _d_r_i_v_e mpartition -c [-s _s_e_c_t_o_r_s] [-h _h_e_a_d_s] [-t _c_y_l_i_n_d_e_r_s] [-v [-T _t_y_p_e] [-b _b_e_g_i_n] [-l length] [-f] Mpartition supports the following operations: p Prints a command line to recreate the partition for the drive. Nothing is printed if the partition for the drive is not defined, or an inconsistency has been detected. If verbose (-v) is also set, prints the current partition table. r Removes the partition described by _d_r_i_v_e. I Initializes the partition table, and removes all partitions. c Creates the partition described by _d_r_i_v_e.

Only one partition can be bootable at a time. d "Desactivates" the partition, i.e. makes it unbootable. If no operation is given, the current settings are printed. For partition creations, the following options are available: s _s_e_c_t_o_r_s The number of sectors per track of the partition (which is also the number of sectors per track for the whole drive). h _h_e_a_d_s The number of heads of the partition (which is also the number of heads for the whole drive). By default, the geometry information (number of sectors and heads) is figured out from neighbouring partition table entries, or guessed from the size. t _c_y_l_i_n_d_e_r_s The number of cylinders of the partition (not the number of cylinders of the whole drive. b _b_e_g_i_n The starting offset of the partition, expressed in sectors. If begin is not given, mpartition lets the partition begin at the start of the disk (partition number 1), or immediately after the end of the previous partition. l _l_e_n_g_t_h The size (length) of the partition, expressed in sectors. If end is not given, mpartition figures out the size from the number of sectors, heads and cylinders. If these are not given either, it gives the partition the biggest possible size, considering disk size and start of the next partition. The following option is available for all operation which modify the partition table: f Usually, before writing back any changes to the partition, mpartition performs certain consistenct checks, such as checking for overlaps and proper alignment of the partitions. If any of these checks fails, the partition table is not changes. The -f allows you to override these safeguards. The following option is available for all operations: Page 33 (printed 7/15/98) mmmmttttoooooooollllssss....1111((((3333)))) MMMMTTTTOOOOOOOOLLLLSSSS ((((11114444mmmmaaaarrrr1111999999997777)))) mmmmttttoooooooollllssss....1111((((3333)))) v Together with -p prints the partition table as it is now (no change operation), or as it is after it is modified. vv If the verbosity flag is given twice, mpartition will print out a hexdump of the partition table when reading it from and writing it to the device. MMMMrrrrdddd The mrd command is used to remove an MS-DOS subdirectory. Its syntax is: mrd [-v] _m_s_d_o_s_d_i_r_e_c_t_o_r_y [ _m_s_d_o_s_d_i_r_e_c_t_o_r_i_e_s... ] Mrd removes a directory from an MS-DOS filesystem. An error occurs if the directory does not exist or is not empty. MMMMrrrreeeennnn The mren command is used to rename or move an existing MS- DOS file or subdirectory. Its syntax is: mren [-voOsSrRA] _s_o_u_r_c_e_f_i_l_e _t_a_r_g_e_t_f_i_l_e Mren renames an existing file on an MS-DOS filesystem. In verbose mode, Mren displays the new filename if the name supplied is invalid. If the first syntax is used (only one sourcefile), and if the target name doesn't contain any slashes or colons, the file (or subdirectory) is renamed in the same directory, instead of being moved to the current mcd directory as would be the case with mmove. Unlike the MS-DOS version of REN, mren can be used to rename directories. MMMMsssshhhhoooowwwwffffaaaatttt The mshowfat command is used to display the FAT entries for a file. Syntax: $ mshowfat files MMMMttttoooooooollllsssstttteeeesssstttt The mtoolstest command is used to tests the mtools configuration files. To invoke it, just type mtoolstest without any arguments. Mtoolstest reads the mtools configuration files, and prints the cumulative configuration to stdout. The output can be used as a configuration file itself (although you might want to remove redundant clauses). You may use this program to convert old-style Page 34 (printed 7/15/98) mmmmttttoooooooollllssss....1111((((3333)))) MMMMTTTTOOOOOOOOLLLLSSSS ((((11114444mmmmaaaarrrr1111999999997777)))) mmmmttttoooooooollllssss....1111((((3333)))) configuration files into new style configuration files. MMMMttttyyyyppppeeee The mtype command is used to display contents of an MS-DOS file. Its syntax is: mtype [-ts] _m_s_d_o_s_f_i_l_e [ _m_s_d_o_s_f_i_l_e_s... ] Mtype displays the specified MS-DOS file on the screen. In addition to the standard options, Mtype allows the following command line options: t Text file viewing. Mtype translates incoming carriage return/line feeds to line feeds. s Mtype strips the high bit from the data. The mcd command may be used to establish the device and the current working directory (relative to MS-DOS), otherwise the default is A:/. Mtype returns 0 on success, 1 on utter failure, or 2 on partial failure. Unlike the MS-DOS version of TYPE, mtype allows multiple arguments. MMMMzzzziiiipppp The mzip command is used to issue ZIP disk specific commands on Solaris or HPUX. Its syntax is: mzip [-epqrwx] Mzip allows the following command line options: e Ejects the disk. f Force eject even if the disk is mounted (must be given in addition to -e). r Write protect the disk. w Remove write protection. p Password write protect. x Password protect u Temporarily unprotect the disk until it is ejected. Page 35 (printed 7/15/98) mmmmttttoooooooollllssss....1111((((3333)))) MMMMTTTTOOOOOOOOLLLLSSSS ((((11114444mmmmaaaarrrr1111999999997777)))) mmmmttttoooooooollllssss....1111((((3333)))) The disk becomes writable, and reverts back to its old state when ejected. q Queries the status To remove the password, set it to one of the passwordless modes -r or -w: mzip will then ask you for the password, and unlock the disk. If you have forgotten the password, you can get rid of it by low-level formatting the disk (using your SCSI adaptor's BIOS setup). The ZipTools disk shipped with the drive is also password protected. On Dos or on a Mac, this password is automatically removed once the ZipTools have been installed. From various articles posted to Usenet, I learned that the password for the tools disk is APlaceForYourStuff. Mzip knows about this password, and tries it first, before prompting you for a password. Thus mzip -w z: unlocks the tools disk. The tools disk is formatted in a special way so as to be usable both in a PC and in a Mac. On a PC, the Mac filesystem appears as a hidden file named `partishn.mac'. You may erase it to reclaim the 50 Megs of space taken up by the Mac filesystem. XXXXccccooooppppyyyy The xcopy script is used to recursively copy one directory to another. Its syntax is: xcopy _s_o_u_r_c_e_d_i_r_e_c_t_o_r_y _t_a_r_g_e_t_d_i_r_e_c_t_o_r_y If targetdirectory does not exist, it is created. If it does exist, the files of sourcedirectory are directly copied into it, and no subdirectory called _s_o_u_r_c_e_d_i_r_e_c_t_o_r_y is created, unlike with cp -rf. BBBBuuuuggggssss This command is a big kludge. A proper implementation would take a rework of significant parts of mtools, but unfortunately I don't have the time for this right now. The main downside of this implementation is that it is inefficient on some architectures (several successive calls to mtools, which defeats mtools' caching). AAAArrrrcccchhhhiiiitttteeeeccccttttuuuurrrreeee ssssppppeeeecccciiiiffffiiiicccc ccccoooommmmppppiiiillllaaaattttiiiioooonnnn ffffllllaaaaggggssss To compile mtools, first invoke ./configure before make. In addition to the standard autoconfigure flags, there are two architecture specific flags available. ./configure --enable-xdf ./configure --disable-xdf Enables support for XDF disks. This is on by default.

When used in conjunction with vold, mtools should uses different device nodes as for direct access. ./configure --enable-new-vold ./configure --disable-new-vold Enables new support for vold on Solaris. This is supposed to work more smoothly than the old support. ./configure --enable-floppyd ./configure --disable-floppyd Enables support for floppyd. By default, floppyd support is enabled as long as the necessary X includes and libraries are available.

For most common systems, default drives are already defined. If you want to add default drives for a still unsupported system, run config.guess, to see which identification autoconf uses for that system. This identification is of the form cpu-vendor-os (for example sparc-sun-sunos). The cpu and the os parts are passed to the compiler as preprocessor flags. The OS part is passed to the compiler in three forms. 1. The complete os name, with dots replaced by underscores. sco3.2v2 would yield sco3_2v2 2. The base os name. Sco3.2v2 would yield Sco 3. The base os name plus its major version. Sco3.2v2 would yield Sco3 All three versions are passed, if they are different. To define the devices, use the entries for the systems that are already present as templates.

If cylinders is 0, the heads and sectors parameters are ignored, and the drive accepts any geometry. offset is used if the DOS filesystem doesn't begin at the start of the device or image file. This is mostly useful for Atari Ram disks (which contain their device driver at the beginning of the file) or for DOS emulator images (which may represent a partitioned device. Definition of defaults in the devices file should only be done if these same devices are found on a large number of hosts of this type. In that case, could you also let me know about your new definitions, so that I can include them into the next release. For purely local file, I recommend that you use the /usr/freeware/etc/mtools.conf and ~/.mtoolsrc configuration files. However, the devices files also allows to supply geometry setting routines.
