Hello I have a display problem with a specific program. some characters are not displayed correctly(like é becomes a U with a 'over it... or even another strange sign like ╠anyway... this makes a professionnal program of mine unusable (TEA), thus if you had any idea for solving that bug... ).This might be a problem coming from my graphics card or maybe my screen or anything else whatever, thank you very much in advance.
Assuming that the progrsm itself is not the culprit, are the program loading a CGI that may be bad?

In MSDOS 6.22, not sure about MSDOS 7 as
that is WinDOS, you can use various keys to
redefine the keyboard layout. You will
need a full manual for MSDOS 6 which
explains this.

The program works fine using pure ms dos mode on my old win98 machine. Im using the same version and autoexec.bat and config.sys with my laptop, and I need TEA to work on my laptop to perform mobile tests. My graphics card is a nVidia Geforce go5700 and my screen is a lcd tft17"(screen of the laptop of course). There arent any nvidia dos drivers available for the gcard and/or acer drivers for the screen.
Well, I hope anyone has the solution...

Is your config or autoexec loading a codepage or country sys or ANSI which may be missing or corrupt on the laptop?
And before we spend much more time and effort, are you really running DOS 6.22 on this "PiV 2,8ghz 512ddr "?
It must zoom along pretty well.

I checked the codepage settings in display.sys and autoexec.bat, I wonder about the line
device=display.sys con=(ega,,1)
as i use a LCD screen shouldnt I use LCD in place of EGA?
But when I use LCD the mode con cp wont work... TTi will make sure about ansi.sys right now.
yes indeed I am running msdos on this computer beacause the program I need works properly only in pure ms dos mode
thanks for the advice.

I think you're getting close.
I think [racking the old brain here] that EGA was a near predecessor of VGA and denotes a resolution capability,; not LCD/TFT/CRT.
Guessing here, but in DOS 6.22 days, there were no LCD/TFT panels available to the general publ;ic; if at all.

This is a bit strange since the characters you describe have the following ASCII codes:
é = 130
â• = 204
Ú in not represented in the common extended ASCII tables, and certainly not in the 7 bit.Look here: http://www.lookuptables.com/
I cannot think of any other solution now than code page as M2G suggested.

Thanks, Nigel.
As a "quick & dirty" I would just REM out the codepage / contrysys, and see if it got better.
Or at least got different.
DOS 6.22 on a P4. I'd like to drive that around the block.

^^
ansy.sys wasnt loaded, its done now but it didnt get better...
About ascii, i did figure this out, but I coulnt go further on that track beacause I lack knowledge ;/. I guess it means that the program uses graphic mode...
But I have not much knowledge in this field...
I tried to rem codepage and country.sys, didnt work...About lcd screens, are there any specific dos drivers for them?
thanx again

do you think ibm convertible LCD driver has any chance of working with a modern lcd screen?
I cant find LCD.CPI easily... has anyone an idea where to find it out?

Dunno about DOS screen drivers.
In the directory from which your TEA program runs, are there .BGI files?
If you can "shell to DOS" within TEA, try running MEM.
It may show something that TEA is loading.
[And it may not.]
The old-time BGIs which Borland, and maybe others use are:
ATT.BGI
CGA.BGI
EGAVGA.BGI
HERC.BGI
IBM8514.BGI
PC3270.BGIIf thry are there, try renaming so as to amke them unavailable:
ren *.BGI *.BG
See if it changes anything.
You can probably throw out CGA & HERC, but that's another story.

I haven't actually seen a Convertible since 1987 or -88, so I don't remember the contents of CONFIG.SYS and AUTOEXEC.BAT of that machine. Neither do I recall any drivers. Sorry.

No BGI files. Though there are .EGA files in the prog directory as well as .HGC and .VGA; HGC prbably referring to herc.
If it leads you to something...
0
Yes, HGC is probably Herc.
Exact file names, with extensions?
Also, any INI or INF or CFG files? Usually smallish.

text editor shows strange patterns in the cfg file (not text format) and there is no configurator.
TEA does not shell ...

I'm running out of brilliance here.
In your BIOS, can you set the screen resolution or the refresh rate?
M2
0
No, not possible...
Refresh rate is fixed at 60hz its the only refresh rate supported by the screen...Whatever, thank you very much for your involvment. If I find the solution I will sure tell you.
Someone had already had the same problem as I(symptoms are very similar). Subject: Graphs display problem. On this forum
But no answer...Once again, thank you very much

Thanks for getting back.
This has been an enjoyable thread for the clear. polite and accurate responses.
But don't go yet.
You may want to try this:
Check the CRC of "matching" files on the problem laptop and the box on which it's running right.
You can get CRC checkers here:
http://www.golden-triangle.com/CRC32.ZIP
There's a CRC32.com, CRC32.exe and a text file which describes one of them, but I forget which.
This will be tedious, but if it uncovers the problem, it may be looked at in retrospec, as having been worth it.

Sorry I ve been away for a while.
I'm going to check this one... I'll give you some feedback this weekend.Thank you again.
