Remove or reset BIOS password from Windows

This method works with Acer TravelMate 2490 laptop with Windows 7, but by the included cmospwd.txt works other BIOS versions and PCs or laptops.

Download and extract to a folder this software:
http://www.cgsecurity.org/cmospwd-5.0.zip
( Info: http://www.cgsecurity.org/wiki/CmosPwd )

Log on to Windows as Administrator priviledges, or run an command prompt with administrating priviledges (Click Start-->Run: type CMD hit Ctr+Shift+Enter)
cd to the extracted directory (e.g. cmospwd-5.0)
then in cmospwd-5.0 cd to windows directory

To work on cmos memory, ioperm need to be installed and running. ioperm gives direct port I/O access for specified ports to user-mode process.

when you are already in e.g. \cmospwd-5.0\windows directory: type “ioperm.exe –i” hit enter.
to start ioperm service: type “net start ioperm” hit enter.
type: “Cmospwd_win.exe /k” hit enter, we will see:

1 - Kill cmos
2 - Kill cmos (try to keep date and time)
0 - Abort
Choice :

Type 1 and hit Enter to clear cmos or 2 to keep date and time.

Reboot computer and former BIOS password gone.

WARNING: You should disable or uninstall ioperm
with "ioperm.exe -u" if you don't want to decrease
your security!

Acer TravelMate 2490 vs. Windows 8.1 error message: ATTEMPTED SWITCH FROM DPC

After installing Windows 8.1 to Acer Travelmate 2490 two errors remain.
1. Atheros wifi adapter.
2. Card reader.

1. Atheros wifi adapter:
You can download Atheros wifi driver for Windows Vista 32 bit from here.
(There are wifi drivers for Atheros, Broadcom and Intel, but I experienced problem only with Atheros.)
Result of installing  looks OK (with setup.exe), but wifi driver won't be installed.

Solution:
In Device manager on wifi card right click.
Then Update Driver...(Choose the map, you extracted drivers before.)
Install driver.

2. Card reader:
It's unnecessary to install driver, because after installing at starting, Windows 8.1 runs to an error:
"ATTEMPTED SWITCH FROM DPC"

Solution:
In Device manager on card reader right click, and click Disable.
It solves the problem, but you won't use card reader of course (an USB card reader is cheap...or you can enabled this device when you need to read an XD or SD memory card - then disable it again).

Asus P4S800-MX SE driver vs. Windows 7 32-bit

It was interesting.
Very old motherboard (Asus P4S800-MX SE -10 years old), but Windows 7 didn't recognize the LAN and the Audio device.
But with Windows XP drivers (you can download from ASUS website) works.
Modern operating system with old drivers...and it works:)
