: As this is an exe file, a windows based disassembler may be the best way to

: 

The format of setup1.exe for the toshiba 1200 is an MZ header DOS executable.
This is the original DOS format for .exe files, the other being .com files, raw
binary images.  Any DOS disassembler will work for MZ header files.  The
16 bit windows file format is known as NE (new executable).  This format
uses a real-mode MZ header with a special value at offset 18h to indicate the
location of the new header.  Meanwhile, the windows 32 bit exe file is known as
PE format, which is a modified COFF file.

Following is the format of an MZ header .exe file:

MZ EXE Format
Intel byte order

The old EXE files are the EXE files executed directly by MS-DOS. They were a
major improvement over the old 64K COM files, since EXE files can span multiple
segments. An EXE file consists of three different parts, the header, the
relocation table and the binary code.
The header is expanded by a lot of programs to store their copyright information
in the executable, some extensions are documented below.
The format of the header is as follows :
OFFSET  Count TYPE   Description
h   2 char   ID='MZ'
 ID='ZM'
0002h   1 word   Number of bytes in last 512-byte page
 of executable
0004h   1 word   Total number of 512-byte pages in executable
 (including the last page)
0006h   1 word   Number of relocation entries
0008h   1 word   Header size in paragraphs
000Ah   1 word   Minimum paragraphs of memory allocated in
 addition to the code size
000Ch   1 word   Maximum number of paragraphs allocated in
 addition to the code size
000Eh   1 word   Initial SS relative to start of executable
0010h   1 word   Initial SP
0012h   1 word   Checksum (or 0) of executable
0014h   1 dword  CS:IP relative to start of executable
 (entry point)
0018h   1 word   Offset of relocation table;
 40h for new-(NE,LE,LX,W3,PE etc.) executable
001Ah   1 word   Overlay number (0h = main program)

Dear all,

Thanks to your intervention, I also find on the same URL the "setup1.exe" program which
should be as useful for my Toshiba T1600 as your T1200:

http://www.csd.toshiba.com/tais/csd/support/files/download/setup1.exe

To find additional information I can also suggest to consult Toshiba Web page:
http://www.csd.toshiba.com/cgi-bin/WebObjects/Toshiba.woa/wa/goto?page=ServiceSupportMain

Unfortunately, I do not reach to unassemble this program with tools at my disposal.

Enjoy,
Joel

hi
I'm perfectly willing to put in the time to do this (expect it to take a
while), and teach myself assembler at the same time, but I need some help
going about it.  A friend of mine loaned me his disassembler program, but
it's designed to run under win95 and winnt.  Can I (should I even try) to
figure it out this way, or does it need to be on the t1200 to have it be
acurate and useful?  Thanks,
   Greg


I not realy an expert in this, but I would only use the windows95/nt if it 
were capible of dissasembaling 16bit code (I am basing this thinking that a 
windows dissasember is designed to disasemble win code, maybe the prog you 
have does both?)

I would use a dos based disasember, don't what one, supose turbo-debuger?

I used to have a good prog that you put in exe's in one end and asm code 
poped out the other end. I will have a look (I downloaded it over a 2 years 
ago)

What does anyone else think, I am not an expert.

hi
That program (named test.com)

I actually have a T1800 NOT a T1200
anyway here is the test3.exe that it uses to change the settings. If anyone 
wants to disasemble it they can, I am NOT going to.

1999-09-29 Thread Celley, Drew

 Just thought I'd see if there was anybody here, since I'm 
 brand new to this.
 I'm hoping to get ELKS on my Toshiba T1200 notebook (8086-10, 
 640K ram, dual
 720K floppies) and use it as a serial console for all of my 
 nifty serial
 devices (hubs, routers, sun boxen, etc.)  Anybody tried 
 anything similar
 yet?

a 720K floppy can contain DOS and Telix -- just enough to use the
serial port for such configs. This is just a suggestion, there's no reason
you *shouldn't* use linux anyway. Are there terminal-emmulation packages for
ELKS?

Ah, the T1200.  I have one, and booted minix on it a while back,
I think I tried ELKS as well.  It booted and ran for awhile, until the damned
Toshiba auto-power-off mechanism kicked in.  then the screen went
blank, and I couldn't get anything to happen until a full system reset
followed by a reboot, then it repeated.

We need to turn off the T1200 auto-power-off mechanism, but I don't have
a HW manual for the unit.

Is that the setup1.exe program?  I found a copy of the diag program on
Toshiba's site, but it doesn't come with the setup program.  I'd be
interested in getting a copy, to see if maybe I can figure out what
exactly it's doing.

I tried it.  That program (named test.com) allowed the bios
setting to change, but it was only active when MSDOS was running, so
it didn't work.
