You need a 80386 processor at least to run UDO. UDO doesn't run on 80286 processors or processors of an older type and I won't compile versions for these old dinosaurs.
If you find a program or batch file named SETUP or INSTALL in the archive please start it and follow the instructions. If the installation fails, please go on reading this chapter.
It failed? Ah, you haven't tested it yet? That's fine that you want to read all the text before you want to experiment. ;-)
Unfortunately the installation of the DOS version is not trivial. Er, I think it is trivial but the experiences of the past have shown me that lots of people have problems installing UDO on a DOS PC although the installation is very simple.
If you haven't heard anything of RSX and EMXRT until now I recommend to read the following two chapters completely. If UDO still refuses to run you have done something wrong or I haven't described the installation process detailed enough.
If you already know what RSX and EMXRT are good for, because you are using emTeX or the GNU utilities) you can skip the next chapter.
OK, you haven't heard anything of RSX and EMXRT yet. That's not a shame. But if you won't know what RSX and EMXRT are good for after having read this chapter, you should feel ashamed. And if some RSX or EMXRT experts recognize some stupid stuff I should feel ashamed.
Well, let's go...
UDO was compiled with the GNU C Compiler (GCC), strictly speaking with EMX-GCC (ported by Eberhard Mattes). GCC is originally a Unix software and Unix has always used 32 bit software. Thus, the EMX-GCC makes 32 bit software, too. And now we have a problem, because you cannot run 32 bit software with DOS without using any tricks.
EMXRT and RSX are responsible for these tricks. These "drivers" allow UDO to allocate huge blocks of memory. Because you have to use different tricks for DOS and Windows there are existing two different "drivers": EMXRT for DOS and OS/2, RSX for Windows.
Please note:
FTP: | Current version of EMXRT can be downloaded from
ftp.uni-stuttgart.de/pub/systems/os2/emx-0.9b/
Current versions of RSX can be downloaded from: ftp.uni-bielefeld.de/pub/systems/msdos/misc/ |
Modem: | You can download the files from the BBS called "Maus MK2 Iserlohn-Kalthof" (+49 2371 944925) from the "Gruppenprogrammteil UDO.PUB". |
Mail: | Just send me a formatted floppy disk and a readdressed envelope and 2 DM (or a convertible amount of money) for postage. |
Let's talk about the installtion of RSX and EMXRT. Of course, you can install only one of the drivers if you run exclusively DOS or Windows. The following descriptions tells you how to install both drivers.
In first place you have to extract the archives. Stop! It's importand that you extract the archives with paths! If you don't let your archiver generate paths nothing will function. I recommend to use UNZIP.EXE. If you extract the RSX archive a directory `RSX\' will be saved. If you extract EMXRT a directory `EMX\' will be saved. If you don't find these directories something went wrong.
You can move the directories to any position of your file system. I recommend to move them to `C:\DRIVERS'. If this directory doesn't exist you have to create one.
After having extracted the archives you have to edit your AUTOEXEC.BAT and to insert the following lines. If you have only installed EMXRT, insert the lines below "Only EMXRT" and so on:
SET EMX=C:\DRIVERS\EMX\BIN\EMX.EXE
SET EMX=C:\DRIVERS\EMX\BIN\EMX.EXE SET RSX=C:\DRIVERS\RSX\BIN\RSX.EXE
SET EMX=C:\DRIVERS\RSX\BIN\RSX.EXE SET RSX=C:\DRIVERS\RSX\BIN\RSX.EXE
If RSX and EMXRT haven't been installed in `C:\DRIVERS' you have to adjust the upper paths.
I think you already know that changes of the AUTOEXEC.BAT are activated when rebooting your computer. Before you reboot your computer I just want to summarize what you have done until now: you have installed some files and you have inserted one or two lines into your AUTOEXEC.BAT. That's all.
And now, reboot your computer.
Let's talk of the easier part of the installation of UDO. The abridged version: extract the archive and add the UDO directory to PATH of your AUTOEXEC.BAT.
But once more I will describe you the installation step by step:
SET PATH=%PATH%;C:\UDO\BIN
