BIOS-Protect Easy - is an effective technology for PC safety. It will lock your system tightly to avoid severe virus such as CIH virus with hardware and software

What is BIOS-Protect Easy ?
April 26, 1999, date on which countless computers were destroyed by CIH virus, is still fresh in our memories. CIH is just a representative of new era viruses which target the mainboard© BIOS and modify its commands to destroy the computer© hardware and software. The destruction they cause to the computer and its internal data makes them superior in every way to any other virus. In order to avoid the infection of such viruses, mainboard manufacturers have entered technology into their own products. One of these technologies is BIOS-Protect Easy, a new application Legend QDI recently launched on new generation mainboard.

BIOS-Protect Easy is made up of three parts:

• JAV, a write-protect jumper switch on the mainboard,
• Flash Write Protect, a built-in soft switch in BIOS, and
• PC Cillin, anti-virus software

INTRODUCTION TO JAV, FLASH WRITE PROTECT AND PC CILLIN: TECHNOLOGY AND FEATURES.
The mainboard original BIOS could only read and not write. With the development of technology, BIOS was soon renewed, and users expected BIOS to be upgraded. Therefore, some mainboard manufacturers made BIOS able to write. However, in order to avoid any accidental modification of BIOS, a write-protect jumper switch on the mainboard (JAV) was also installed. Although JAV function is similar to that of the write-protect switch on floppy disks, BIOS can only write when the computer has just been turned on. This kind of design may seem a little contradictory: most of the time the switch in on write-protect; therefore, to upgrade BIOS, the chassis must be opened and a very small switch on the mainboard must be turned on. After upgrading, the switch must then be turned off. If the switch is not on write-protect, it apparently becomes useless. After consideration, manufacturers decided to remove JAV. However in order to prevent accidental modification of BIOS, they added a function to determine whether or not BIOS can write. This function is comparable to a soft switch. Manufacturers never imagined a virus would directly attack BIOS. When attacking BIOS, this kind of virus destroys the write-protect soft switch in BIOS, then moves on to modify BIOS commands, destroying the data on the hard disk, paralyzing the system, losing data, and at the worst burning out the mainboard and the chips. April 26, 1999 was the date manufacturers regretted removing JAV from the mainboards.

Legend QDI new generation mainboards(WinneX series, CenturieX series, Advance 5/133E, BrillianX 1s/2000) reinstalled JAV. When the switch is off , BIOS can in no way be modified, however powerful a virus may be.

If for any reason (for example negligence of the user) JAV is in write mode, Flash Write Protect can prevent BIOS from being accidentally modified. When the soft switch is in write-protect mode, BIOS cannot be modified, but DMI can still be upgraded.

In fact, the whole BIOS-Protect Easy technology can act in several ways to prevent viruses from attacking BIOS, therefore avoiding destruction of BIOS. Of course, however rigorous one may be, there is always a risk. Therefore, regularly using anti-virus programs and avoiding the usage of pirated software or any virus-infected software still remains the best way to protect one© computer.
