Subject: 27. Common Reason Why Memory Allocation Fails
27.1 BACKGROUND
A common error received when first learning to use Int 21h Function 48h,
allocate memory, is error code 8, insufficient memory available.
Usually, the programmer then writes a small program that only allocates
memory, and the program still fails. This situation is quite puzzling
because there should be hundreds of kilobytes of memory available but
this function reports that there is insufficient memory for a few
hundred bytes. The reason is that DOS generally allocates all available
memory above the loaded program to that program. Therefore, there is no
more memory to allocate, so the request fails.
27.2 .COM FILES
Since a .COM file does not contain any header information, the DOS
loader has no way of determining how much memory is required for a
program beyond the physical size of the program. Even this number is
deceptive because it does not include a stack. Therefore, DOS always
allocates all available memory above the program to the program.
To use the allocate memory function, the programmer must release that
extra memory using Int 21h Function 4ah, Set Memory Block Size. Given
that generally there is more that 64 Kbytes of memory, the DOS sets
Stack Top to just under that value, it is generally safe to release all
memory above 64 Kbytes.
27.3 .EXE FILES
The amount of memory the DOS allocates to the loaded program depends
upon a value in the .EXE header. This value is called Maximum
Allocation and is a word starting at offset 12. This value specifies
the number of 16-byte paragraphs beyond the image size wanted by the
program to execute. This value must be equal or greater than the
Minimum Allocation, which is the number of 16-byte paragraphs beyond the
image size required by the program to execute. This space generally
contains uninitialized variables and the stack.
The value of Maximum Allocation is set by the /CPARM Option for the
Microsoft Linker. By default, the linker sets this value to 0ffffh that
will causes DOS to allocate the largest block of available memory. This
memory can be used as a heap, print buffer, etc.
27.4 DETERMINING HOW MUCH MEMORY IS AVAILABLE TO A PROGRAM
In the PSP, at offset 02h, DOS loads a word that is the segment address
of the next Memory Control Block or Arena. Subtracting the PSP from
that value at offset 02h will be the number of memory paragraphs
allocated to the program. The number of bytes can be calculated by
shifting that number to the left by 4 bits, multiplying by 16, the size
of a memory paragraph.
27.5 HOW TO DEALLOCATE MEMORY AT THE START OF A PROGRAM
If you want to load and execute another program, you must release memory
to make room for the program. Also, since the largest chunk of memory
is allocated already to the program, all requests to allocate memory
generally fail.
Again, to use the allocated memory function, the programmer must release
the extra memory above the program use as for a .COM file above. The
problem here is where is the end of the program. The answer is not as
simple as with the .COM file. There are two basic solutions.
1. If you use the .dosseg option, the Microsoft Linker will define a
label, _end, at the end of the DGROUP. Since the .dosseg option also
places any FAR data segments between the code and DGROUP segments, you
can release all memory above that label.
2. If you do not want or are unable to use the first option, use an
include file which declares all segments used by your program. Define a
label in the last segment and use it as the _end label in the first
example.
27.6 TELLING DOS NOT TO ALLOCATE ALL AVAILABLE MEMORY AT STARTUP
If you are using a Microsoft Linker or a compatible linker, you can use
the /CPARMMAXALLOC or /CP switch. Set this switch to /CP:1. The Linker
places 1 at offset 0ch in the .exe header. This tells DOS that you only
need a maximum of 1 paragraph of memory above your program. DOS
compares this to the minimum memory required at offset 0ah in the .exe
header. If the max is less than the minimum, DOS assigns the minimum.
Therefore, your program gets only the memory necessary for it to
execute, and all other memory above your program is available for
allocation.

Subject: 28. Volume Serial Numbers
28.1 VOLUME SERIAL NUMBER FORMAT
The volume serial number was introduced with DOS 4.0 as part of an
extended boot record and is created through you either FORMAT a disk or
use DISKCOPY to create another disk. The serial number is a function of
the time/date of the formatting or the diskcopying. Note that DISCOPY
generates a new volume serial number so a DISKCOPY is not an exact image
of the source diskette.
28.2 CALCULATING THE VOLUME SERIAL NUMBER
For example, say a disk was formatted on 26 Dec 95 at 9:55 PM and 41.94
seconds. DOS takes the date and time just before it writes it to the
disk.
Low order word is calculated: Volume Serial Number is:
Month & Day 12/26 0c1ah
Sec & Hundrenths 41:94 295eh 3578:1d02
-----
3578h
High order word is calculated:
Hours & Minutes 21:55 1537h
Year 1995 07cbh
-----
1d02h
Note that DOS interrupt 21h Functions 2ah, Get DOS Date, and 2ch, Get
DOS Time, are particularly suited to getting the date and time for
calculating the Volume Serial Number.
28.3 READING AND SETTING THE VOLUME SERIAL NUMBER
To read the Volume Serial Number, use the IOCTL call, Int 21h function
440dh Minor Code 66h, Get Media ID. To write the Volume Serial Number,
use the IOCTL call, Int 21h function 440dh Minor Code 46h, Set Media ID.
WARNING! These IOCTL calls use a structure that also contains the
volume label and file system type. So that you do not create errors
with these values, I recommend that you always Minor Code 66h to
initialize the structure before setting the Volume Serial Number to a
new value and writing it back to the disk.

There are two sources for this information. The first is available from
Intel. The Tools Interface Standards Committee has prepared the
following documents:
ftp://ftp.intel.com/pub/tis/omf11g.zip
The readme file in each .zip file states that the document is the
Relocatable Object Module Format Specification, V1.1.
Unfortunately, both files unzip into documents formatted for Postscript
printers. Adobe's Acrobat can not display them, but Ghostscript can.
If you need GhostScript, you can get it from the following site. Read
the ftp://ftp.cs.wisc.edu/pub/ghost/aladdin
29.2 MICROSOFT
The second is from Microsoft. This file is located at:
ftp://ftp.microsoft.com/Softlib/MSLFILES/ss0288.exe
This file expands into ascii text files that are the Microsoft Product
Support Services Application Note: Relocatable Object Module Format.
These files date from 1992. Also included are the .lib file format and
the CodeView extensions.
29.3 COFF format
This information is specific for DJGPP COFF but is this the same as used
by Microsoft (I believe)

Subject: 30. Rebooting from Software
30.1 WARM AND COLD REBOOT
Within DOS, there are two types of rebooting. There is the warm reboot
that is evoked by pressing the "Ctrl-Alt-Del" key combination. During
this reboot, all Power On System Tests, POSTs, are performed with the
exception of the memory tests. In addition to the POSTs, interrupt
vectors are reinitialized and system timers reinitialized. In other
words, the BIOS code initializes the computer system to such a state
that the computer system is ready for loading the operating system.
Issuing an interrupt 19h does the loading of the operating system.
The second type of rebooting is a cold reboot that occurs when the
system is turned on. The only difference between a cold reboot and a
warm reboot is the performing of the memory tests.
30.2 PERFORMING A REBOOT FROM SOFTWARE
Whether a cold or warm reboot is performed depends upon the value if the
reset flag in the ROM BIOS data area. If this flag is set to 1234h, a
warm reset is performed. Any other value results in a cold reboot.
Usually a zero is loaded for the cold reboot. Code snippets to do this
are:
ROMBIOS_DATA segment at 0400h
org 72h
ResetFlag dw ?
ROMBIOS_DATA ends
ROMBIOS segment at 0f000h
org 0fff0h
Reset label far
ROMBIOS ends
In your code:
mov ax, seg ROMBIOS_DATA
mov ds, ax
ASSUME ds:ROMBIOS_DATA
mov ResetFlag, 1234h ; or 0 if cold reset is desired
jmp Reset
30.3 WARNINGS!
Neither the warm nor the cold boot flushes buffers, system, smartdrv,
and EMM386, or notifies TSRs. This can lead to lost of data. The best
source code that considers most of this is:
ftp://ftp.simtel.net/pub/simtelnet/msdos/bootutil/reboot33.zip
Full source code is available.
30.4 JUST USING INT 19H
Using this interrupt alone will only reload the operating system onto a
computer system that may not be initialized properly for it. The
interrupt vectors are not reset but the TSRs that have hooks into the
interrupt table may be overwritten. Obviously, this can lead to the
system hanging if one of these hooked and overwritten interrupts is
called. Other problems can be timers not reset or add-on cards not
reinitialized properly. So, do NOT use Int 19h to reboot the computer.
30.5 USING F000:E05B INSTEAD OF F000:FFF0 AS THE JUMP ADDRESS
In the original IBM ROM BIOS, the instruction at f000:fff0 was a long
jump to f000:e05b. Some programs skipped the jump at f000:fff0 and went
directly to the second address which is the start of the reset procedure
in ROM BIOS. I checked my 386 with non-IBM BIOS, and the start of the
reset procedure is at the same address. I believe that using the second
address is dangerous because there is not any guarantee that it will
stay the same. In addition, if you are rebooting the computer what is
the reason in saving a few cycles! Stay with the address f000:fff0 as
the jump there always will take the execution path to the correct code.

Subject: 32. Pseudo Random Number Generator in Assembly Language
Mark Adler wrote a set or pseudo random number generators based upon
algorithms from Knuth's "Art of Computer Programming", vol 2, 2nd ed.
The file comes with full assembly source and .obj files for all major
memory models. While written to link with Turbo C, the .obj files when
linked with Microsoft C worked well, except for the procedure that
return a double random number. The reason was that the return protocol
is different between Borland C and Microsoft C. Once the code was
modified to work with Microsoft C, the code worked well.
To test the algorithms, I created an array of 100 random numbers and
then generated random numbers and tried to determine if the original
pattern was ever repeated. My program kept the length of the longest
matching series. For real or double, the longest matching series was
one after more than a billion random numbers. For ints, 0 and 1 as the
only selections produced the longest matching series of 31 matches after
more than a billion random numbers. Increasing the range of acceptable
numbers quickly reduced the longest matching series to 2 in over 250
million random numbers. My short testing revealed that the longest
matching series seldom increased after this number.
Lastly, to test the distribution, I counted the number of hits for each
number between 0 and 100. I collected about 100,000 hits for each
number. The standard deviation was only 319 or less than 0.33%.
While my testing was not a rigorous mathematical testing of the
algorithm and its implementation, I believe for most uses, these
procedures are adequate.

Subject: 33. Command Line Arguments
33.1 WHERE IS THE COMMAND LINE
DOS loads the command line into the PSP. The length of the command line
is stored in a byte at offset 80h. The command line is stored in the
next 127 bytes starting at 81h. As, generally, there is a space between
the filename and the start of the command line argument; a space usually
is the first character in this string. The string is terminated with a
carriage return character, 0dh.
At startup for both .COM and .EXE format programs, DS and ES point to
the PSP.
33.2 HOW TO ACCESS THE COMMAND LINE ARGUMENTS
See Subject #8, How to Redirect STDERR to a File. I have written a
demonstration program that contains assembly language startup code that
parses the command line arguments onto the stack and provides them as
argc and *argv[] to the main procedure. Anyone interested in accessing
command line arguments should look at this code.

MicroASM is written by Ole Saether. It is a Windows 95 & NT windows
editor with support for MS-DOS command line assemblers.
With MicroAsm you can:
Create and edit text files.
Run the files through your favorite command-line assembler.
Automatically highlight lines containing errors.
To learn more about it and download it, visit:

36.6 TASM IDE
Joost Vrielink has developed a Turbo Assembler IDE. It is free for
downloading from his web site:
http://www.angelfire.com/in/tasm
The IDE is an editor just like WordPad, but compile/link/run/debug can
be accomplished with just one click. It also has a built-in
dec/hex/bin/oct converter, and syntax highlighting is almost finished.
It is perfectly suited to make simple 16-bit DOS programs within the
Windows 95/98 environment. Changes are being added quite often, so
remember to return and check every now and then.

Subject: 38. How to Optimize for the Pentium
39.1 PENTIUM OPTIMIZATION SITE
The below site is updated as new information becomes available and
contains information not found elsewhere.
http://announce.com/agner/assem
38.2 LITERATURE AVAILABLE FROM INTEL
Much useful literature can be downloaded free from Intel's WWW site:
http://www.intel.com
The documents are in various different file formats. If a particular
document is in a format not supported by your word processing software,
then you may seek an appropriate file viewer somewhere on the Internet.
Many software companies are offering such file viewers free to support
their file formats.
Tutorials for Optimizing the Pentium, and Pentium Pro/Pentium II can be
downloaded from:
http://developer.intel.com/design/perftool/cbts/pentopt/index.htm
http://developer.intel.com/design/perftool/cbts/pproopt/index.htm
Manuals for the Pentium and Pentium Pro processors can be downloaded
from:
http://developer.intel.com/design/pentium/manuals/
http://developer.intel.com/design/pro/manuals/
Detailed information on the MMX processors can be found in the
documents:
"MMX Technology Developers Guide", and "Programmers Reference Manual",
both of which are available from:
http://developer.intel.com/drg/mmx/manuals/
Many other sources other than Intel also have useful information. I
would particularly recommend:
http://www.x86.org.

Subject 46. High Level Assembly Language
Randy Hyde has developed a High Level Assembly (HLA) language as a tool
to help teach assembly language programming and machine organization to
University students at the University of California, Riverside. The
basic idea was to teach students assembly language programming by
leveraging their knowledge of high level languages like C/C++ and
Pascal/Delphi. At the same time, HLA was designed to allow advanced
assembly language programmers write more readable and more powerful
assembly language code.
There is much documentation but it still is in development. If you want
to give HLA a try, its URL is:
