NTVDM CPU encountered an illegal instruction

I have a jsp page that displays a graph using an applet and recently updated the page to use dynamic versioning for the JVM. A couple of weeks ago (late Jan 2005) the dynamic versioning was working fine, downloading and installing the latest version of Java as required (it was then 1.4.2_06 and at the time of this post, still is).
However now (early Feb 2005), I am finding that after downloading the Java plugin and beginning the install, I am getting the error below:
16 bit MS-DOS Subsystem
The NTVDM CPU encountered an illegal instruction.
C5:0555 IP:0288 OP:63 6f 6e 74 65 Choose 'Close' to terminate the application.
Has anyone else experienced this problem with v1.4.2_06 (I have seen on this forum someone had problems with v1.4.2_05 but problem went away when v1.4.2_06 was released a while back)?
I have tested on a few PCs in my office, all running Windows XP sp2 and IE 6.0.2900.2180.xpsp_sp2, same result.
cheers

I have the same problem with XP sp2. Did you find a fix?

Hi there,
I am also experiencing this problem, but with 1.4.2_06. Last week (late Jan 2005) the dynamic versioning was working fine, downloading and installing the latest version of Java as required.
However now (early Feb 2005), I am finding that after downloading the latest version of Java and beginning the install, I am getting this error.
I was hoping that you may have heard of a cause or solution for this problem?
Many thanks

The NTVDM CPU has encountered an illegal instruction

Hello,
I have a problem with my laptop. Once I sign into Windows I get this error message:

NTVDM CPU has encountered an illegal instruction using Windows XP Firefox 8.0.1 (IE8 does not cause this error)

I receive the error every time I turn on and off my pc and then start Mozilla Firefox. The problem does not happen if I use IE8.
I have gone to the control panel and removed Firefox 8.0.1 and then downloaded a new version and installed. I still experience the issue.

Make sure that you do not run Firefox in compatibility mode. 
You can open the Properties via the right-click context menu of the Firefox desktop shortcut and check that in the "Compatibility" tab. 
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.

16 bit MS-DOS NTVDM illegal instruction when Webstart tries to install JRE

Hi
When I configure a JNLP to download a JRE (if necessary) using the following line,
<j2se version="1.4.2_01" href="http://java.sun.com/products/autodl/j2se"/>
it downloads a JRE but then fails while trying to install it, in a couple of ways.
The first problem I get is a warning that the applications digital signature has an error. It has expired. It expired on the first of May this year at 1am. Ignoring that I press <Run> and proceed with the installation.
Now the big error, a windows dialog box (I'm using NT here, and it happens on other similar machines in the institution as far as I can tell):
Title: 16 bit MS-DOS Subsystem
Body: C:\DOCUME~1\<profilename>\APPLICA~1\Sun\Java\DEPLOY~1\cache\6.0\ext\E12499~1\J2RE-1~1.EXE
The NTVDM CPU has encountered an illegal instruction.
C5:085b IP:01df OP:63 6f 72 61 74 Choose 'Close' to terminate the application.
<Close> <Ignore>
Even if I choose "Ignore" the result is a broken/partial install of the JRE, with the only directories being j2re1.4.2._10 containing a file called dp14210.vbs and a bin directory. In the bin directory there is only a subdirectory called server, and in server there are two files, Xusage.txt and jvm.dll.
Note that I have not mis-typed the name of the directory above: although the jnlp requests jre1.4.2_01 the directory that is created is for jre1.4.2_10.
I have tried this for various other JREs including 1.6.0_01 and 1.5.0_12 and I get the same problem with the out-of-date certificate and the 16 bit MS-DOS Subsystem illegal instruction.
The name of the file that gets executed after I click "Run" depends on the version of the JRE I am trying to install and follows a naming convention. In the case of the 1.5.0_12 jre the file name is "jre-1_5_0_12-windows-i586-p-iftw.exe" and in the case of the 1.4.2_01 it is "j2re-1_4_2_01-windows-i586-iftw.exe"
Any help appreciated, thanks,
Anthony Holland

I'm positive JRE 5 can't be installed on NT. According to this 1.4.2 neither (I thought it could, all I knew about was this ). Maybe you could try giving a look at jnlp specs to see if any particular 'os' attribute can 'work' to auto-install on NT, but I think you're facing a dead end.
Bye.
PS: did you try downloading the exe and installing it via prompt? If that fails too, I guess you can call it off.
PPS: you can install [1.4.1_07|http://java.sun.com/products/archive/j2se/1.4.1_07/jre/install-windows.html] (if it's enough for your purpose).

Illegal instructions in everything!

Recently, almost every program has been failing intermittently with "Illegal instruction (core dumped)" or some variant thereof. For some periods of use, the system is unusable, not to mention leaves program artifacts all over the place.

checking out the coredumps shows the illegal instructions seem to be in libpthread (which would explain why they're intermittent):

Check if there's an option possible to disable TSX altogether in BIOS.
Alternatively, you can patch the libpthread binary Run objdump -d /usr/lib/libpthread.so.0 and find elision_init. If it looks like this...

then open it in some hex editor, go to byte 11acc and change 0f 95 c2 to 90 90 90. Should be enough. The modified binary doesn't crash on my AMD box, but make a backup just in case

"illegal instruction" during install of xapian-ruby-bindings (AUR)

In the installation process of xapian-ruby-bindings from aur the command
/usr/bin/ruby -I.libs -I. ${dir}$tst
is run from within a shell script. On my system, it causes an "illegal instruction" error, thus the installation fails.
I read in another thread* that this is somehow related to programs being compiled "for SSE2 or something similar". I do not know anything about that, anyway below is my /proc/cpuinfo

By the way, I also get an "illegal instrucion" error when calling (not installing) the mu** program (installed from AUR). This may or may not be related.

If you think so . . . I did not provide the output deliberately, because it really does not contain anything interesting besides "illegal instruction". Anyway, here are the last lines of the xapian-ruby-bindings build:

"Ungültiger Maschinenbefehl" is german for "illegal instruction". (This one never gets translated, no matter what I do with LC_ALL etc.. I hope you do not mind the other german words—I can run the build again with english language settings if anything is not self-explanatory.)
mu is shorter:
$ mu find bla
Ungültiger Maschinenbefehl
EDIT: Replaced german output by its english equivalent, except for mu's error message, which is german regardless of LC_ALL.

Solaris 10 Net Install - Illegal Instruction

Hi Colleagues,
I 've been wrestling with this for awhile and can't seem to correct the problem. Searching the forum and the Web has also not returned any solutions.
Problem: I'm trying to install Solaris 10 10/09 on a SunFire V100 (128MB Ram, 40GB and 160GB HDD, CD-rom) using the DVD image from Sun.
Here is the result the I receive:

You're going to need a lot more RAM in that tiny beastie:
[http://www.sun.com/software/solaris/specs.jsp|http://www.sun.com/software/solaris/specs.jsp]
Thankfully, there are four DIMM slots on the V100 systemboard and you can max it out at 2GB of PC133 memory.

Is it valuable for processor(CPU) to use the instruction set of java virtual machine?

I've got an idea that processor(CPU) would use an instruction set like java virtual machine instead of assembly language whose instruction includes MOV ,INC ,ADD AX, ....
Thus this type of processor(CPU) can support any java program just like Windows with a java virtual mache software package.
Thus the operating system like Android, Windows Phone can be writen in Java. For embeding system with no operating system , programs can also be writen in Java directly.

Well, this is rather off-topic but… Sun once designed a Java-Core that was running Java natively, but they never went anywhere with it. Java code, when created well, runs reasonably fast. It seems just that most of todays programmers don't know, what they're doing, when they're writing Java code.

Ultra 60 console port gives OK Illegal Instruction

I've got an Ultra 60 whose video no longer displays. The ethernet port had died a couple of weeks previously. I had been trying to swap in a couple of base 100 ethernet pci cards into, to see if they were recognized. I had installed one last week, but didn't have time to bring up the machine until this week. I discovered the video no longer displays but the monitor gets a signal as it refreshes during reboot. Tried a couple of monitors and 3 cables, no luck, everything works the same, just no video.
Found a thread about an Ultra 10 with a similiar problem and they discussed going through the console port (serial port A). I tried hooking up a null modem cable to my thinkpad, installed TeraTerm, but when I try to connect (9600, 8, N, 1), I do get an OK prompt. When I try to press any key though, I get "Illegal Instruction".
I've gone through the reference guide, service guide, and searched the forums, but I can't find anyone else that's had this problem. Would anyone have any ideas or suggestions?
thanks,
kevin

Power cycle the box and watch if it comes back to the ok prompt (or boots).
If you still get illegal instruction power off and remove any PCI cards and try again. could be a device corrupting the NVRAM.
Also a setenv defaults (from ok prompt) might clear a corrupted NVRAM. this however will clearout any custom boot settings.
If you can try to do a
ok> printenv
and capture the settings first.

IBook Illegal Instruction, Black Screen... Death?

I have an ibook G4... I just got an iPhone and was told to update iTunes before synching.
I chose to do the most recent software updates on iTunes, iPhone, and the Security Update.
I walked away while downloading/updating and came back to a white/grey screen with "Illegal Instruction at %ssro: ff85e778 %ssr1: 00081010" blah blah... "type to reboot or type to shut down"...
I did the reboot... It rebooted and I got a blue screen with a small icon that flashed between a "sad mac" atop a file folder and a "?". I let it run thru that cycle for 5 minutes and shut it down. I rebooted and the same "Illegal Instruction" came up, so I just shut it down, then restarted to get my install cd in, then restarted and tried booting from disk...
I get nothing now. No matter what I do, my iBook chimes up, spins up, but the screen is black.
HELP!

Welcome to Apple Discussions!
Here's a place to start:

Try the resets and see if they help. Then see if you can boot from your install CD. If you succeed, navigate to Disk Utility and see if you can repair your boot drive.
Does your iBook still have its original hard drive? If so, it could be beginning to go south, and that could be the underlying reason why things have gotten messed up.
Good luck!

I can't down load itunes. I get an error message, NTVDM has encountered a System Error The handle is invalid.

16 bit MS-DOS Subsystem
C:\WINDOWS\system32\msiexec.ex NTVDM has encountered a System Error The handle is invalid.
Choose 'Close' to terminate tha application.
Close Ignore

Okay. It seems unlikely to be the class of similar problems caused by various Symantec programs blocking installs.
It's a bit of a mystery in the first place why the 16 bit DOS subsystem is running in this context. (The iTunes installer is 32-bit on XP machines.)
Just in case it's a damaged NTVDM, perhaps try an sfc /scannow:

Does that clear up the error?

NTVDM CPU encountered an illegal instruction
