error in ioctl call formatting floppy disk

* There is a bug in the driver that makes it impossible to format a * floppy as the first thing after bootup. Maybe a new * ioctl() should be created to be able to modify them. * I have fixed the shift values to the ones I always use. */ /* 0 * Modifications for ``Sector Shifting'' by Rob Hooft * modeled after the freeware MS-DOS program fdformat/88 V1.8 by * Christoph H. * * TODO: Errors are still not counted properly. * * 7: Added DMA allocation & DMA functions. */ /* * 2 - Hennus Bergman: Added better error reporting, fixed * FDC data overrun bug, added some preliminary stuff for vertical * recording support. */ /* * Automatic floppy-detection and formatting written by Werner Almesberger * who also corrected some problems with * the floppy-change signal detection. */ /* * 28.02.92 - made track-buffering routines, based on the routines written * by (Lawrence Foard). Thus I cannot * call 'floppy-on' directly, but have to set a special timer interrupt * etc. A hardware interrupt * handler may not sleep, or a kernel panic will happen. */ /* * As with hd.c, all routines within this file can (and will) be called * by interrupts, so extreme caution is needed. Seems there are problems with several drives. I should check for more errors, and do more graceful error * recovery. I've tried my best to get it working, * but I don't like programming floppies, and I have only one anyway. This makes some things easier (output_byte reset * checking etc), and means less interrupt jumping in case of errors, * so the code is hopefully easier to understand.
