How about looking it up in a data sheet? It's a lot of stuff you need to
know to program this thing correctly... too much to tell you by typing :-|.

Could you be loading a TSR after the AUTOEXEC completes?

There used to be a problem (up to DOS 4 I think, don't know about DOS 5) 
with FORMAT where it would give the track zero error if "the DMA buffer 
spanned a 64K segment boundary".

If you aren't loading a TSR, try loading one (or more, of different sizes).

They are not necessarily lost files.  If you have hidden files, or a hidden
directory, all the files in that hidden directory are marked as unmovable
blocks.  I believe some of the other norton utilities will tell you if you
have any hidden directories, I think a program such as file-find (ff) will
parse hidden directories.

If it is 1/4 of your hard drive, then it's most likely not just hidden files
causing the problem.  But it's probably wise to check all possibilities
before running a bunch of disk recovery programs.

	I have seen quite a few people talking about the fact that they have 
upped the bus speed on their boards.  I was just wondering, is this simply done 
by replacing the oscillator crystal?  Or is there something else that must be 
done with the crystal changeout?  Ids there an easy way to determine whether the 
board will support the new speed?
	Post replies to the group, I'm sure there are others who would be 
interested int the answer. (Assuming that this is not a subject that has been

The program FDFORMAT ver 1.8 has options for sector sliding, but doesn't
have the optimizing routine mentioned for diskrw.
FDFORMAT can also format diskettes to non-standard formats.  I use it to
format all my old 360K diskettes to 820K for use on a 1.2MB drive.
You need to included FDREAD to load as about a 160 byte TSR to be able
to read non-standard formatted diskettes.
You can find it at Simtel as PD:<MSDOS.DSKUTL>FDFORM18.ZIP

Personally, I've tried different sector sliding values and have found
none that works better than the standard no-offset.

Try the new Telemate ver 3.02.  It does almost all you ask.
It's a DOS program that uses several windows for editor, backscroll, DOS
shell, terminal, etc, has VT102 (don't know what 20X is), Zmodem
built-in, easy to use, mouse driven, shareware, capture log.
It won't run as a TSR, but you can browse through the backscroll window
or use the editor while downloading with no problems.
You can get it at Simtel:

	I would really appreciate it if someone could give me a hand here.  We
(the computer lab I work in) just picked up a nice, new CD-ROM, the first one
for us.  And while it's nice to be able to pull up CR-ROMs on there, it would
be even nicer to also be able to play CDs on it.  Now I know that there are
programs in existence out there for allowing someone to play a CD on a CD-ROM,
but I don't know where to look.  Is there perhaps an ftp site I might try
looking for something in?  Or maybe a way of getting it to play a CD in another
way?  Any info would be much appreciated.
	Seeing as I don't normally frequent this newsgroup (sorry, but there
are only so many hours in a day), I would appreciate it if all replies were
sent via email, and if I get very much response, I will post a summary of what
I receive.  Thanks much for any help.

dBase IV question

I would like to import some data from a dBase program into Lotus 1-2-3
so I can use the fancy printing features of its ""Impress" add-in.  In
my dBase program I create a bunch of variables e.g.

SUM COST FOR TERR="1111" .AND. PROD="VOL" .AND. TYPE="MLS" TO MVAR1
SUM COST FOR TERR="1112" .AND. PROD="VOL" .AND. TYPE="MLS" TO MVAR2
SUM COST FOR TERR="1113" .AND. PROD="VOL" .AND. TYPE="MLS" TO MVAR3

(etc.)

I now want to take MVAR1, MVAR2 and MVAR3 and get them either into
a database or into cells of a spreadsheet.  I know how to write these
to a flat file.  But to bring a flat file to lotus requires you then
"parse" the data to get the data elements into individual cells, not
a lot of fun.

I would appreciate some insight on how best to accomplish this.

Thanks!

Date: Tue, 28 Jul 1992 18:58:57 GMT

Hi all.

I'm trying to program the FDC directly through the I/O ports (0x3f2-0x3f5).
I think I have some things figured out but there are still a lot of things
which are unclear.  For instance:
  1.  Which FDC commands provide an interrupt (IRQ6) when complete?
  2.  The Read command takes 7 parameters (1 byte each):
	1. cylinder #
	2. head #
	3. sector #
	4. bytes per sector
	5. end of track
	6. gap 3 length
	7. data length (if parameter 4 is 0)
      - Since the 'bytes per sector' parameter is only 1 byte, does that mean
        that the max sector size if 255 bytes?  What happens to the 256th byte.
      - What does the 'end of track' parameter do?
      - What is the 'gap 3 length'?
      - What does the 'data length' parameter do?
  3.  How does one determine the # of cylinders, # of sectors, # bytes per
      sector, and # of tracks?
  4.  What do the Read/Write Deleted Data commands do (i.e. what is 'deleted'
      data)?
  5.  What does the Read ID command do (i.e. what is an ID)?
  6.  What do the Scan Equal/Low or Equal/High or Equal commands do?
  7.  What is the 'step rate time'?
  8.  What is the 'head load/unload time'?
  9.  What is MFM mode?
 10.  How does non-DMA mode work?
 11.  What does 'skip deleted-data address mark' mean?

As you can see I'm still rather uninformed.  I ordered the Intel Peripherals
book and it should be here in a few days but I'm not sure if it will contain
any information on the FDC.  So... if anyone can answer any/all of my questions
I'd be happy to hear from you (if you'd rather give me a detailed explanation
of how data is stored on a disk, that info. would be happily received too).

The UART chip with the 16 character buffer is the NS16450.  The two 4
port serial cards I have all have these chips.  I don't know what the
1 character buffer UART chip number is, but I wasn't able to find any
NS16450's on the visible side of the tower model motherboard.

I run SLIP at 19.2kbaud, but I use a different type of SLIP server
than the annex.  Even using the NS16450, I get lots of overruns and
dropped characters.  Occasionally the serial driver just stops sending
out characters.  I modified the serial driver to not notify me about
overruns and to trigger at 4 characters (instead of 14), but it's
still losing.

I wasn't able to find any obvious problems with the serial driver's
code, so I suspect the machine is taking an inordinate amount of time
servicing higher-priority interrupts.  Then again, I have no real
information about what is going on.

In general, I'd have to say the RT makes a poor SLIP server.
