: As this is an exe file, a windows based disassembler may be the best way to : work on it. If you would rather work on it under Linux, try ndisasm which : comes as part of the NASM package. It is a very powerful disassembler, but : some knowledge of the format of the file you are trying to disassemble. I : am not sure what the format of a .exe file is. Any pointers anyone? : 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) Greg

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.

RE: Anybody using this list?
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. tom __ Get Your Private, Free Email at http://www.hotmail.com

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. tom __ Get Your Private, Free Email at http://www.hotmail.com Test3.exe
RE: Anybody using this list?
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. Greg

Re: Anybody using this list?
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.
