Guide to install CmosPwd and remove password:

1. Download & extract to a folder. I put it in drive D like this: d:\ cmos
2. 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 (ring 3) using Ke386SetIoAccessMap and Ke386IoSetAccessProcess
kernel functions.

Log on to Windows as Administrator priviledges and do as follow: (see picture):

a. Click Start-->Run: type CMD hit Enter on your keyboard.
b. now us the CD command of Dos to come to d:\cmos\windows. (here is: d: hit enter; cd cmos hit enter; cd windows hit enter).
c. when you are already in d:\cmos\windows in drive D then: type “ioperm.exe –i” hit enter.
d. to start ioperm service: type “net start ioperm” hit enter.
e. ok, 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.
