Hi!

I managed to make a program to physically format a floppy disk on 386bsd.

It is just a quick hack.  There is a possibility that use of this package
may cause trouble.

So...

USE THIS PACKAGE ON YOUR OWN RISK.

Enjoy!

XFIRST OF ALL:
X
X  386BSD is an excellent OS.  Now we can throw away our good old MS-DOS
X...almost.
X
X  It is very sad to find things which we cannot do with 386BSD but can
Xwith MS-DOS...for example, formatting floppy disks.  So first of all I
Xmade a formatter for formatting floppy disks.
X
XCHANGES:
X
Xsys/i386/isa/fd.c:
X    Adding fdioctl().
X    Adding formatting process to fdintr().
X
Xsys/sys/ioctl.h
X    Adding FDIOCFORMAT and FDIOCM.
X
XHOW TO INSTALL:
X
X1) Apply patch to kernel, as shown below.
X
X    # cd /sys
X    # patch -p < fdformat.diff
X
X  This may be rejected because of the changes applied to i386/
Xi386/conf.c.  In such a case, add fdioctl manually by checking
X.rej.
X
X  Make sure ioctl to /dev/rfd* calls fdioctl.
X
X2) Add
X
X    options    FDFORMAT
X
Xto sys/i386/conf/MYCONFIG.
X
X3) Re-configurate kernel as below.
X
X    # cd /sys/compile/MYCONFIG
X    # make depend
X    # make
X
X4) Copy the new kernel to /, as shown below.
X
X    # mv /386bsd /386bsd.old
X    # cp 386bsd /386bsd
X
X5) Make and install fdformat, as shown below.
X
X    # make
X    # make install
X
X6) Reboot.
X
X    # sync; sync; sync;
X    # fastboot        <- or shutdown, halt, whatever you like.
X
X  Now all the instllation is done.
X
XHOW TO USE:
X
XUsage:    % fdformat [special device]
X
X  If special device is not specified, you will be asked if you want to
Xformat /dev/rfd0a.  If you choose y, formatting will start.
X
X  Devices are
X
X    a:    1.4MB
X    b:    1.2MB
X    c/d:    360KB
X
X  For more information, see the array in the beginning of i386/isa/fd.c.
X
XKNOWN BUGS:
X
X1) It is rather slow to read from and write to floppy disks formatted
Xwith this formatter.  Will someone please tell me the correct interlib
Xand length of GAP3?
X
X2) Fdioctl only checks if the device is opened writable.
X
X#This means anyone can execute format with ioctl(fd, FDIOCFORMAT, &track).
X
X  If you think this may cause trouble, try to do with changeing the
Xpermission for /dev/rfd??.
X
X3) This program may format floppy disks when it shouldn't, which can
Xcause trouble.
X
X4) This program can not work well on TOSHIBA J3100SLVW.
X
