Hidden Hidden refresh is performed independent of Refresh the CPU, as long as the CPU does not try to access local memory or the AT bus during a hidden refresh cycle, refresh will be transparent to the CPU. The CPU can continue to execute from its internal cache and execute internal instructions during hidden refresh without any loss in performance due to refresh arbitration.

CMOS SETUP of System BIOS, you probably already realize the inherent benefits in this hardware-based anti-Virus solution. The single most important attribute of anti-Virus of 317 is that it features preemptive virus action. This technology, called JumpLoading™ allows ChipAway Virus to gain control of your system very early in the boot process —...
Additional anti-virus software Just to give you even more peace of mind, 317 main board attached some anti-virus software that you can use to scan for viruses other than boot-sector viruses. With this software, 317 represent a whole solution against every type of virus.
4. 5 How ChipAway Virus Work Since ChipAwayVirus is auto-checking of floppy diskettes when they are accessed, and when a virus is found, the warning message will be display. ChipAwayVirus Warning Boot sector on diskette is infected by a virus. Do not boot the system from this diskette.
» Always use a nde-based anti-virus product that is not extreme ly dependent on pattem updates. By following these guidelines, and by using 317 anti-virus feature, you should be able to work productively in a virus-free environ ment. ChipAway Virus...
