Removed $Log$ section and patch kit headers. And here is the full
message for Bruces changes: >From: bde@kralizec.zeta.org.au (Bruce Evans) >Subject: fixes for fd driver I think I've fixed some bugs in the 0.2.4 fd driver. 1. The main cause of hangs was that there was no timeout for seeks. So attempting i/o with no floppy in the drive hung iff a seek was required. 2. Opens of unattached drives were allowed. The kernel usually paniced soon after due to a bad pointer. 3. Some timeout functions ran at splclock() instead of splbio(). This may not have mattered. 4. The state machine was left in a funny state after a timeout. 5. Some function headers were new-style. 6. I picked up some code posted the other day to implement label ioctls. Now `disklabel fd0' works. See a comment for how to modify conf.c.

- * Revision 1.3 1993/08/12 09:21:20 rgrimes
- * Fixed poor timeout code in out_fdc. The timeout counter was not being
- * reinitialized between while loops. Added comments about what was going
- * on in the out_fdc routine.
- *
- * out_fdc now returns if the direction bit is not set in time instead of
- * trying to wait for MRQ to get cleared.
- *
- * Revision 1.2 1993/07/15 17:53:04 davidg
- * Modified attach printf's so that the output is compatible with the "new"
- * way of doing things. There still remain several drivers that need to
- * be updated. Also added a compile-time option to pccons to switch the
- * control and caps-lock keys (REVERSE_CAPS_CTRL) - added for my personal
- * sanity.

- * Revision 1.1.1.1 1993/06/12 14:58:02 rgrimes
- * Initial import, 0.1 + pk 0.2.4-B1
- *
- * Revision 1.10 93/04/13 16:53:29 root
- * make sure turning off a drive motor doesn't deselect another
- * drive active at the time.
- * Also added a pointer from the fd_data to it's fd_type.
- *
- * Revision 1.9 93/04/13 15:31:02 root
- * make all seeks go through DOSEEK state so are sure of being done right.
- *
- * Revision 1.8 93/04/12 21:20:13 root
- * only check if old fd is the one we are working on if there IS
- * an old fd pointer. (in fdstate())
- *
- * Revision 1.7 93/04/11 17:05:35 root
- * cleanup timeouts etc.
- * also fix bug to select teh correct drive when running > 1 drive
- * at a time.

- * first working version.. some floppy controllers don't seem to
