The EP-BXB-S is based on the Intel 440BX chipset, an AGPset offering 100MHz Bus Clock, supporting dual Slot-1 Pentium II or Pentium III CPU operating at 233-550 MHz. The AGP Slot is compatible with any AGP compliant adapter providing an immediate doubling (or quadruple) in the maximum available 2D/3D graphics bandwidth without reducing performance of other PCI cards. AGP Technology also allows Virtual Reality applications to use as much texture buffer space as they need without expensive card or hardware upgrades.??The EP-BXB-S mainboard features the advanced Adaptec AIC-7890 Ultra-2 SCSI controller. This controller provides support for Low Voltage Differential (LVD) SCSI devices as defined under the Ultra-2 section of the SCSI-3 standard. LVD SCSI devices allow for data transfer rates of up to 80 Mbytes/sec and can use cable lengths of up to 12 meters! Additionally the AIC-3860 Adaptec controller is also provided for backwards compatibility with single-ended (SE) legacy SCSI devic...
