1.1 Featuress
This P55XU/XUW SCSI Motherboa rd is the newest ATX form fa ctor ba sed
member to our SCSI Motherboa rd solution products fa milies. It incorpora ted with
Intel 6
th
genera tion 430TX Chipset a nd Ada ptec new PCI Ultra SCSI AIC -
7860(AHA-2940AU) / Ultra Wide SCSI AIC-7880(AHA-2940UW) tha t double/
four times the SCSI speed. In order to support fully plug a nd pla y I/O, a n Ultra I/O
tha t conta in keyboard a nd rea l time clock is used f or users to enjoy the plug and
pla y function. This SCSI motherboa rd ha s designed with ATX form fa ctor to
improve the ea sy a ccess memory module, long a dd -on ca rd support a nd some of
the new fea tures tha t tra ditiona l AT form fa ctor ca n not a chieved.
Run with fa ster a nd use one single jumper ca p to a djust the CPU speed is very
importa nt function tha t this SCSI Motherboa rd supports. It supports P54C up to
200 MHz and Intel’s new generation P55C processor that support MMX
technology. Of course, the AMD K6 from 200 MHz, K5 up to 200 MHz a nd Cyrix
6x86L up to PR200 MHz a ll a re supported on this SCSI motherboa rd. The fixed
fea ture on-boa rd 512KB L2 pipelined burst ca che design well prepa red to run
hea vy a pplica tions.
Run with fa ster system memory is a nother plus o n this SCSI Motherboa rd to
outperform the whole system performa nce. It equipe 4 of the 72 pin SIMM that
support both fa st pa ge a nd EDO DRAM a lso with three of the 168 pin DIMM
memory socket tha t support the new synchonous DRAM.
