Chapter 1 Specification
This mainboard features an integration of the powerful AMD proces-
sors Athlon/Athlon XP/Duron and the North Bridge VIA Apollo KT400
plus South Bridge VT8235, with which the whole system performance
supports 333/266/200 MHz system bus.
VIA Apollo KT400 plus VT8235 supports on-board AMD processors
to implement the 333/266/200MHz Front Side Bus, the AGP 8X/4X
interface, the LPC Super I/O, the DDR *400/333 MHz SDRAM, the 6-
channel AC’97 Audio interface, the USB 2.0 interface and ATA 133/100/
66 data transfer rate. This chapter is to introduce to users every ad-
vanced function of this high performance integration.
** If any difference is fo nd between the man al description
and the Mainboard yo are sing, please look p the Errata/
Update Slip enclosed inside for the correction or pdated
information, or else contact the Mainboard Dealer or visit o r
Web Site for the latest man al pdate.
