The 586ITX, equipped with a 321-pin Zero Insertion Force (ZIF) CPU
socket, is a Pentium
processor-class system board supporting Intel
Pentium
processors running at 90MHz, 100MHz, 120MHz, 133MHz,
150MHz, 166MHz and 200MHz frequencies. The 586ITX also supports
Intel Pentium
processor with MMX™
technology - 166/200/233MHz, fu-
ture Intel
Pentium
OverDrive
processors, AMD-K5™
PR90/PR100/
PR120/PR133/PR166, and AMD-K6™
PR2-166/PR2-200/PR2-233.
The 586ITX system board can support 8MB to 256MB of system
memory. It is equipped with two DIMM sockets using x64 EDO, fast
page mode or SDRAM, and 4 SIMM sockets using EDO or fast page
mode x32 DRAM. This system board also supports 512KB pipeline
burst SRAM.
The 586ITX system board can support ACPI Specification, Modem
Wake-Up, PC 97 Compliance, and Dual Function Power Button to en-
hance its performance. ACPI (Advanced Configuration Power Interface)
has energy saving features which enable operating systems to reliably
manage and coordinate power planes, PnP (Plug-and-Play) peripherals,
and cooling fans. ACPI is the specification of Microsoft
'
s anticipated
PC 97 "OnNow" design allowing continual "power on" with reduced en-
ergy consumption. The Modem Wake-Up feature allows the "sleeping"
PC to power on to respond to incoming calls.
PC 97 Compliance defines the adherence to Plug-and-Play compatibil-
ity, hardware power management, and 32-bit device drivers for Win-
dows 95
& Windows NT
specifications. Dual Function Power Button
allows two distinct OFF modes. In Sleep mode, a PC powers down but
not off. In Soft-Off, a PC shuts down but requires a reboot to "awaken"
it.
The 586ITX design is based on the Peripheral Component Interconnect
(PCI) local bus and Industry Standard Architecture (ISA) standards. It is
equipped with 3 dedicated PCI slots, 2 dedicated 16-bit ISA slots and 1
shared PCI/ISA slot.
