New Features
BIOS-ProtectEasy
The BIOS of the mainboard is contained inside the Flash ROM. Severe viruses such as CIH
virus are so dangerous that it may overwrite the BIOS of the mainboard. If the BIOS has
been damaged, the system will be unable to boot. We provide the following solution which
protects the system BIOS from being attacked by such viruses.
There are two choices which implements this function.
1. Set the jumper (JAV) as closed, the BIOS can not be overwritten.
2. Set the jumper (JAV) as opened, meanwhile set “Flash Write Protect” as Enabled in
AWARD BIOS CMOS Setup. In this way, the BIOS can not be overwritten, but the DMI
information can be updated.
Ultra ATA/100
According to the previous ATA/IDE hard drive data transfer protocol, the signaling way to
send data was in synchronous strobe mode by using the rising edge of the strobe signal.
The Ultra ATA/33 protocol doubles the burst transfer rate from 16.6MB/s to 33.3MB/s, by
using both the rising and falling edges of the strobe signal, and Ultra ATA/66 doubles the
Ultra ATA burst transfer rate once again (from 33.3MB/s to 66.6MB/s) by reducing setup
times and increasing the strobe rate. In the same way, the burst transfer rate of Ultra
ATA/100 is higher than ATA/66 (from 66.6MB/s to 100MB/s)by reducing the pulse width
from 30ns to 20ns and increasing the strobe rate.
It can be added into existing systems without the need for termination devices, new cable,
or other hardware changes, industry implementation of ATA/100 will provide an inexpen-
sive, simple, non-proprietary, high-speed method of host to storage access.
The 80-conductor, 40-pin cable standard in ATA/66 has enhanced reliability and bee
carried forward to ATA/100. of course, backwards compatible with ATA/33.
PC-133 Memory
PC133 SDRAM Unbuffered DIMM defines the electrical and mechanical requirements for
168-pin, 3.3 Volt, 133MHz, 64/72-bit wide, Unbuffered Synchronous DRAM Dual In-Line
Memory Modules (SDRAM DIMMs). Relatively , the peak bandwidth of PC-133 memory is
the 33% higher than PC-100 memory. These latest SDRAMs are necessary to meet the
enhanced 133MHz bus speed requirement.
