Features

The AcerAltos 9100B Series is a dual-processor system board built on an ATX
baseboard that supports the Intel Pentium II CPU processor running at 350/100
MHz and 400/100 MHz. The 9100b Server is based on Intel's 440BX chip set and
takes advantage of 100 MHz Front Side Bus architecture. It contains an exclusive
connector for the CPU board that carries two slots for the Pentium II CPU
modules.
The host bus interface supports a Pentium II processor with 100 MHz bus
frequency. It also supports synchronous DRAM (SDRAM) DIMMs.
The AcerAltos 9100B Series supports PCI IDE, and enhanced power
management. It also supports Ultra DMA/33 synchronous DMA-compatible
devices.
A 50-pin Fast SCSI (Small Computer System Interface) and a 68-pin Ultra Wide
SCSI comes with the AcerAltos 9100B Series to connect SCSI devices. Wide SCSI
supports 16-bit transfers while fast SCSI uses a 8-bit bus that doubles the clock
rate to support data rates of 40 Mb/s.
The AcerAltos 9100B Series system board and other standard features such as
two UART NS16C550 serial ports, one parallel port with Enhanced Parallel Port
(EPP)/Extended Capabilities Port (ECP) features, a diskette drive interface, and
two embedded hard disk interfaces. The board also includes a built-in 10/100
Mb/s Intel 82557 network interface controller, and a PCI video controller with 1
