I have some legacy embedded 8086-hosted software that I would like to run on a PC, mainly running test scripts through it. This is not too difficult except that the code contains some input/output port operations.
Does anyone know of any existing software that can intercept these i/o port operations and substitute memory reads/writes? This would allow me to simulate the i/o operations.
I have the source code for my embedded code and could amend it to use memory operations but I would rather not do this.
Best regards
Paul

I'm having a lot of page-faults in my app. Also, there is a lot of disk IO.
I know this is simple, but can anyone show me how to calculate the performance hit for each IO. What is the formula. Maybe give an example. That would be very helpful.
thanks for answering my simple question.

Hi. Are you using a XML parser in your app?

Command prompt (Windows XP, SP2, all updates) has become *painfully slow*  When typing it takes 2 seconds or more for a character to appear, also the commnad prompt window does not move smoothly accross the screen.
Anybody ever experienced this?

It sounds like your video acceleration settings have been turned down. Go into Control Panel > Display > Settings tab, click Advanced, go to Troubleshoot tab and move the Hardware Acceleration slider all the way to the right.
Typically this setting is turned down automatically when a video driver fault is detected. Consider checking for an updated video driver. Also check that your current video driver is correct for your hardware.
Finally, ensure you're using the XP command prompt, cmd.exe, rather than the 16-bit Windows 9x-compatible command.com. cmd.exe is a lot faster.

Hmmm, I checked that, but unfortunately that does not seem to be the case
However, here is some new development. When I restart my machine cmd works fine, so I thought it must be some application causing this and it seems I was right.
As soon as I open Word 2003, cmd slows way down, the more documents I open, the slower it gets.
Anybody knows why in earth Word would slow down the cmd?

There are many way that I suggest you to check it:
1. Check the physical memory of your computer. How much your capacity of the physical memory?
2. Check the size of the page file. To check it go to the Property of My Computer -> Advance tab -> Setting button under Performance group and Click on the Advance tab of the appear dialog box. To change the size of the virtual memory, click on the Change button. Then set the size for the virtual memory. Or you can move the page file to the other drive to optimize your computer performance.
3. Check the hard ware component for your computer. Whether you have to much device driver to load during the time that your computer start. So it will consume you a lot of memory from your computer.
4. Check the Performance under Administrative tool to identify the current operation of your computer.

Mike,
Can the same thing happen just after a fresh upgrade to Win XP SP2?
Could not restart but then applied a registry fix for AMD64. Can now restart but was slow to get to login screen. But now I just get a blank screen with my default wallpaper. Ctrl+Alt+Del works to get task manager. Then icons and taskbar appeared after 5-10 mins. All operations very very slow. Then I had to leave for work on Monday morning. Won't be home again until tomorrow night.

Are you tried this way?
If you tried can you explain me?
|

I never try yet, but I can do it at my testing machine at home and I will let you know tomorrow.

Use NTBackup to back up the system state.
Alternatively you could promote another server to a domain controller, force the data to replicate, then remove the first DC before reinstalling.

Hi guys,
I would like to know
(1) how i can make sure that bfore actual bootloader executes; my own designed bootloader will execute?
(2) how to configure actual boot loader so that it will always ask me
" press any key to continue"?
Thanx
Tom

(1) Write and install your own BIOS.
(2) Write and install your own NTLDR.

But How i can write my own BIOS?. I mean to say what things/ files/ tools are required to do that?
Also same question for NTLDR.
Thanx

have a look at grub, linux's "grand unified boot loader"... there's a grub 4 dos, or someting like that, which i got to work on windows... since it's open source, you might be able to change it to what you want it to do...

Thanx

i don't know. i haven't looked at the source code. that's what i would have to do to answer your question. and besides, i'm not going to hand you the answer on a silver platter. what would be the point? you wouldn't learn anything from it.
the only way i can think of expanding your booloader would be to use another, which you then customize, unless you can get microsoft to release the source code for ntldr, which i very much doubt.

-----------
The instruction at"0x7572eb3c" referenced memory at
"0x90909090".
the memory could not be "written"
-----------------------
thanks

This is an error of the memory. Until now i do not find any way to solve the problem and i just recognize that if you keep your system update to date with the security patch or service pack.

im having problems in creating processes & threads under visual c++ 6, the problem is that, the unistd.h lib is not recognised and i can run the fork(), execvp() functions.
is there any way to bypass the problem?

There's too much mismatch between the POSIX fork/exec model of process creation and Win32's model to patch it up in the C runtime library. While the _exec* family are implemented, they all create new processes directly, rather than via fork().
If you want to be a native, use CreateProcess.
To create a thread, use _beginthreadex. It's recommended to only use CreateThread if you're using Windows CE (where the C run-time and Windows core libraries are integrated in coredll.dll) or if you're not using the C run-time at all.
