DON'T say N here or you - WON'T BE ABLE TO USE YOUR FLOPPY TAPE DRIVE. - - The ftape module itself no longer contains the routines necessary - to interface with the kernel VFS layer (i.e. to actually write data - to and read data from the tape drive). Instead the file system - interface (i.e. the hardware independent part of the driver) has - been moved to a separate module. - - To compile this driver as a module, choose M here: the - module will be called zftape. - - Regardless of whether you say Y or M here, an additional runtime - loadable module called `zft-compressor' which contains code to - support user transparent on-the-fly compression based on Ross - William's lzrw3 algorithm will be produced. If you have enabled the - kernel module loader (i.e. have said Y to "Kernel module loader - support", above) then `zft-compressor' will be loaded - automatically by zftape when needed. - - Despite its name, zftape does NOT use compression by default. - -config ZFT_DFLT_BLK_SZ - int "Default block size" - depends on ZFTAPE - default "10240" - ---help--- - If unsure leave this at its default value, i.e. 10240. Note that - you specify only the default block size here. The block size can be - changed at run time using the MTSETBLK tape operation with the - MTIOCTOP ioctl (i.e. with "mt -f /dev/qft0 setblk #BLKSZ" from the - shell command line). - - The probably most striking difference between zftape and previous - versions of ftape is the fact that all data must be written or read - in multiples of a fixed block size. The block size defaults to - 10240 which is what GNU tar uses. The values for the block size - should be either 1 or multiples of 1024 up to a maximum value of - 63488 (i.e. 62 K). If you specify `1' then zftape's builtin - compression will be disabled. - - Reasonable values are `10240' (GNU tar's default block size), - `5120' (afio's default block size), `32768' (default block size some - backup programs assume for SCSI tape drives) or `1' (no restriction - on block size, but disables builtin compression). - -comment "The compressor will be built as a module only!" - depends on FTAPE && ZFTAPE - -config ZFT_COMPRESSOR - tristate - depends on FTAPE!=n && ZFTAPE!=n - default m - -config FT_NR_BUFFERS - int "Number of ftape buffers (EXPERIMENTAL)" - depends on FTAPE && EXPERIMENTAL - default "3" - help - Please leave this at `3' unless you REALLY know what you are doing. - It is not necessary to change this value. Values below 3 make the - proper use of ftape impossible, values greater than 3 are a waste of - memory. You can change the amount of DMA memory used by ftape at - runtime with "mt -f /dev/qft0 setdrvbuffer #NUMBUFFERS". Each buffer - wastes 32 KB of memory. Please note that this memory cannot be - swapped out. - -config FT_PROC_FS - bool "Enable procfs status report (+2kb)" - depends on FTAPE && PROC_FS - ---help--- - Optional. Saying Y will result in creation of a directory - `/proc/ftape' under the /proc file system. The files can be viewed - with your favorite pager (i.e. use "more /proc/ftape/history" or - "less /proc/ftape/history" or simply "cat /proc/ftape/history"). The - file will contain some status information about the inserted - cartridge, the kernel driver, your tape drive, the floppy disk - controller and the error history for the most recent use of the - kernel driver. Saying Y will enlarge the size of the ftape driver - by approximately 2 KB. - - WARNING: When compiling ftape as a module (i.e. saying M to "Floppy - tape drive") it is dangerous to use ftape's /proc file system - interface. Accessing `/proc/ftape' while the module is unloaded will - result in a kernel Oops. This cannot be fixed from inside ftape. - -choice - prompt "Debugging output" - depends on FTAPE - default FT_NORMAL_DEBUG - -config FT_NORMAL_DEBUG - bool "Normal" - ---help--- - This option controls the amount of debugging output the ftape driver - is ABLE to produce; it does not increase or diminish the debugging - level itself. If unsure, leave this at its default setting, - i.e. choose "Normal". - - Ftape can print lots of debugging messages to the system console - resp. kernel log files. Reducing the amount of possible debugging - output reduces the size of the kernel module by some KB, so it might - be a good idea to use "None" for emergency boot floppies. - - If you want to save memory then the following strategy is - recommended: leave this option at its default setting "Normal" until - you know that the driver works as expected, afterwards reconfigure - the kernel, this time specifying "Reduced" or "None" and recompile - and install the kernel as usual. Note that choosing "Excessive" - debugging output does not increase the amount of debugging output - printed to the console but only makes it possible to produce - "Excessive" debugging output. - - Please read <file:Documentation/ftape.txt> for a short description - how to control the amount of debugging output. - -config FT_FULL_DEBUG - bool "Excessive" - help - Extremely verbose output for driver debugging purposes. - -config FT_NO_TRACE - bool "Reduced" - help - Reduced tape driver debugging output. - -config FT_NO_TRACE_AT_ALL - bool "None" - help - Suppress all debugging output from the tape drive. - -endchoice - -comment "Hardware configuration" - depends on FTAPE - -choice - prompt "Floppy tape controllers" - depends on FTAPE - default FT_STD_FDC - -config FT_STD_FDC - bool "Standard" - ---help--- - Only change this setting if you have a special controller. If you - didn't plug any add-on card into your computer system but just - plugged the floppy tape cable into the already existing floppy drive - controller then you don't want to change the default setting, - i.e. choose "Standard". - - Choose "MACH-2" if you have a Mountain Mach-2 controller. - Choose "FC-10/FC-20" if you have a Colorado FC-10 or FC-20 - controller. - Choose "Alt/82078" if you have another controller that is located at - an IO base address different from the standard floppy drive - controller's base address of `0x3f0', or uses an IRQ (interrupt) - channel different from `6', or a DMA channel different from - `2'.

If this is the case you'll encounter "reduced data rate - because of excessive overrun errors" messages and lots of retries - before ftape finally decides to reduce the data rate. - - In this case it might be desirable to tell ftape beforehand that - it need not try to run the tape drive at the highest available - speed. If unsure, leave this disabled, i.e. leave it at 2000 - bits/sec. - -config FT_ALPHA_CLOCK - int "CPU clock frequency of your DEC Alpha" if ALPHA - depends on FTAPE - default "0" - help - On some DEC Alpha machines the CPU clock frequency cannot be - determined automatically, so you need to specify it here ONLY if - running a DEC Alpha, otherwise this setting has no effect. - |
