Intercepting IO Operations

5-Mar-05 13:30

Get the tool from here.[^], but i think it just a read only version for NTFS (because it is a trail version)...

Or you can try to use Bart PE[^] to build a bootable windows xp or 2003 (run windows from CDROM) to access the partition and delete any file from drive C:. If you have any problem don't forge to let me know.

Try it and good luck!!!

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

Page Faults

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?

Has anybody experienced this problem??

Command prompt (Windows XP, SP2, all updates) has become *painfully slow* Frown | :(

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 Frown | :(

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.

How to backup ActiveDirectory?

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.

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.

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

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...
