Features

The ACERALTOS11000 is a dual-processor system board built on an
ATX baseboard that supports the Intel Pentium II CPU processor
running at 333/66 MHz, 350/100 MHz, 400/100 MHz, 450/100 MHz,
and 500/100 MHz with external multiprocessor GTL. 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 66 or 100
MHz bus frequency. It also supports synchronous DRAM (SDRAM)
DIMMs.
The ACERALTOS11000 supports PCI IDE, universal serial bus (USB)
host/hub, 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
Wide SCSI comes with the ACERALTOS11000 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 20 Mb/s.
The ACERALTOS11000 system board also supports the USB
(Universal Serial Bus) connector, 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 LAN controller.
