Brad Kummer asked how to make a DS/DD boot disk for his Atari ST.  Simply
copying the files to a DS diskette doesn't work.  The problem is that a
boot sector, properly set up for a DS drive, has to be written onto the
disk.  The Atari BIOS provides the necessary functions, and a boot can be
written to disk with the BIOS calls in the following code fragment.

	#include	<osbind.h>
	char	buf[512];

	Floprd(buf, 0L, SSDRV, 1, 0, 0, 1);	/* Read boot from SS drive */
	Protobt(buf, 0x01000000, 3, 1);		/* Convert to DS form */
	Flopwr(buf, 0L, DSDRV, 1, 0, 0, 1);	/* Write boot to DS drive */

	where:	SSDRV and DSDRV are the drive numbers of the single and
		double sided drives respectively.  Drive A: is 0, and drive
		B: is 1.

Unfortunately, you need the developer's kit to do this.  Is there a way to do
it without?  Of course, once you have one copy of a DS disk with a boot on it
your can clone it with image copies of the disk.

Well the bad news is that you cannot currently make a bootable? DSDD
diskette. You are stuck with using your SSDD drive as drive A, and the 
big guy as drive B. Conflicting rumours abound as to Atari's intention
to remedy this situation, but the best theory is that it won't be fixed
until all of their supply of SS drives are exhausted. (Also hard drives
won't be available until they figure that everyone went for a DS drive.)

Really this ain't so bad, unless you just wanted to trash your small drive
and go for two big ones. I figure that the final configuration: 
	A: SSDD
	B: DSDD
	C: HD
is a pretty good one.

I believe that you have to do the following to make a bootable DS/DD
disk.

   1) format the DS/DD disk
   2) open the DS/DD disk
   3) open the TOS disk and copy the TOS image and the decktop file
      to the DS/DD disk by dragging them to the DS/DD window.

You won't be able to make a bootable disk by using the copy utility for some
reason, but I think the above procedure will work.  Happy Hacking...

Sorry, but you CAN use the double sided drive as drive A. The only restriction
is that your boot disk must be formatted single sided.

Good news and bad news:

The good news is that I do have a program which makes a bootable
double sided floppy disk for the ST.

The bad news is that I don't know how to distribute it.  I can
post it to the net, but how are those folks who are running nothing
but LOGO going to download it?  I really can't afford the time to
make and send diskettes for anybody who might want one.  I did give a
copy to my Atari dealer (the Program Store at White Flint Mall in Rockville
Md) but that only helps those in this area.

Does anybody have a downloader written in LOGO?
