- Latest release date: 2/13/88 version 1.5
- -------------------------------------------------------------------------------
- Changes making version 1.20 IAU.EXE
-
- 1. Cursor is not displayed now for a nicer display during the read-format-
- write operation.
-
- 2. Some of the source was modified for Turbo-C compatibility vs. C86 C.
-
- 3. A potential bug with large hard disks was fixed.
-
- 4. Time displays fixed (if you change interleave twice, the old "finished"
- time remained on the screen, giving misleading information).
-
- 5. 'C' source code has been passed through the XENIX "cb" (C beautifier)
- program, causing the structure to be easier to follow.
-
- 6. Some of the comments in the .DOC files were slightly changed.
-
- 7. The .DOC files may now be in either your current (default) directory, or in
- any directory in your "PATH=" environment string.
-
- Note: If you want to change the text of the .DOC files, use any text editor
- (or WardStar in the Non-Document mode). The program will reformat your text
- during run-time to fit in the pop-up window. This is true for all earlier
- versions, too.
-
- Note: Some of the screen subroutines and other subroutines are from the Hammer
- library (O.E.S. Systems). I use at least one (and usually several) of their
- routines in just about every 'C' program I write. I can recommend it highly.
-
- Changes making version 1.21 IAU.EXE 11/17/87
-
- 1. When the cylinder count goes above 655, the percent complete is now
- correct.
-
- 2. There are two versions of the executable; the 8088 version is IAU.EXE, and
- the 186/286/386 version is called IAU286.EXE. It runs a little faster on
- these processors. The only difference is a few compiler switches - not in
- the implementation.
-
-
- -------------------------------------------------------------------------------
- Changes making version 1.3 IAU.EXE 12/11/87
-
-
- 1. A new displayed value is shown -- the current interleave value is measured
- and displayed. This works for most STANDARD configurations, except for the
- following special situations:
-
- A) If you are using disk cacheing, results will be wrong.
- B) If your hard disk isn't 17-sector, no result will be shown.
- C) If your current interleave is too small for your system (such as 1
- on most systems), you will get the get the "effective" interleave
- value. This means that if your interleave is set for 1, and your
- controller can't support it, then the calculated value will be 18.
- This is the value which will be displayed, and this is the
- performance (penalty) that your other software will experience.
-
- Thanks to Ed Eggleston for this suggestion for a new feature.
-
-
- -------------------------------------------------------------------------------
- Changes making version 1.4 IAU.EXE 1/6/88
-
- 1. Version 1.3 hangs when used on an 8088 or 8086 machine. I linked in the
- wrong library for that version. As far as I can tell, it can't ruin any
- data on your hard disk -- it just hangs. Version 1.4 is correct. Thanks
- to George Nail for his time in reporting it.
-
- 2. I deleted the 286 version for quicker upload/download times.
-
- 3. Now the program measures the performance on your system to calculate the
- best interleave for current configuration.
-
- 4. The "current interleave" measurement was fine tuned.
-
- 5. A dial-up phone number for questions/answers/suggestions is now displayed
- on the screen. This is a unix system and you can mail to me. When you
- connect, answer the Login prompt with "hello" and press return (without the
- quotes). You can use uucp from your unix system to that number, also:
-
- mail concord!dad
-
- or via USENET ...wang7!concord!dad
-
- If you do, let me know how to get back to you (phone number, hours to call,
- system id, etc.) You may also use amateur packet radio if you'd like:
-
- kz1o @ wb1dsw
-
- -------------------------------------------------------------------------------
-
- Changes making version 1.5 IAU.EXE 2/13/88
-
- 1. The sectors-per-track was fixed at 17. While this accomodates most hard
- disk drives, some of the newer (Maxtor, etc.) drives use RLL encoding,
- which gives more sectors per track. The 1.5 version allows this value to
- be read and the corresponding table is built for this parameter.
-
- 2. The source code was removed from the archive file since most users weren't
- using it anyway. The source code is still avail-able for anyone who wants
- it, either via modem or mail to the author. Because of restrictions on
- some of the Hammer Library routines (copyrights) you must obtain these on
- your own (or write them).
-
- 3. Most users weren't aware that the .DOC files are read at run time, and can
- be changed by anyone who wants to. They are read and formatted for the
- little window on the screen, so if you do edit them, you needn't worry
- about margins, etc. Just be sure that you don't use a text editor which
- uses hidden characters (for example, WordStar). My algorithm counts and
- displays all of the characters, and I'm not sure what would happen if some
- of them were non-printing types.
-
- 4. The phone number given for help is CORRECT; however, because of various
- problems, it doesn't always answer. The best time to try is late at night
- and on weekends, but I try to keep it up all the time. In some cases you
- might get an answer by voice instead. If you have a pressing problem, you
- could call the regular (voice) number at (603) 228-4683. Please make it
- during reasonable east-coast times, since I have a family. Oh, yes -- my
- CompuServe ID is 70441,2456.
-
- 5. The display of the "Best Value For You" value is not always correct. The
- value displayed as the "best so far" is the correct number, but a typo
- caused the wrong variable to be passed to the printf statement. Now the
- program displays the correct value.
-
- -------------------------------------------------------------------------------
-
-
- I am always interested in change and improvement suggestions that you may
- have. Most of the updates were made because someone had an idea about how
- to make the program better. As a result, it is a much better program than
- when originally written.
-
-
- I didn't want to say this before, but now I will so that it's out in the
- open:
-
- Some people have called with questions about the program,
- and indicated that they have had problems of one kind or
- another. Due to the nature of this program's operation,
- people usually run it once and shelf it. Because of human
- nature, it seems that I am more eager to solve problems for
- people who have sent me pictures of dead presidents ($$$).
- I didn't write this program for money, but it helps to pay
- the phone bill, etc. any case, I'll do what I can to help
- you.
