It was neccessary to remove and replace CMOS battery (CR2032).
After replacing CMOS battery the "View only item" message was gone.

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!
