The second microprocessor must have the same internal operating frequency as the first. A minimum of 64 megabytes (MB) of system memory, upgradable to a maximum of 1 gigabyte (GB) by installing combinations of 64- and 128-MB unbuffered dual in-line memory modules (DIMMs), or 256-MB registered SDRAM DIMMs in the four DIMM sockets on the system board. The unbuffered 72-bit-wide error checking and correction (ECC) SDRAM DIMMs installed in PowerEdge 2300 systems support ECC to check for and correct memory errors. ECC is performed by the memory controller in the system chip set. A basic input/output system (BIOS) that resides in flash memory on the ISA bus and can be upgraded if required. The system board includes the following built-in features: Six PCI and two ISA expansion-card connectors, located on the system board.

PCI slots 1 through 4 are unshared slots; PCI slot 5 is shared with ISA
slot 5 and PCI slot 6 is shared with ISA slot 6.
²
An integrated advanced graphics port (AGP) video graphics array (VGA)-
compatible video subsystem with an ATI 3D RAGE PRO super VGA (SVGA) video
controller. This video subsystem contains 2 MB of synchronous graphics random-
access memory (SGRAM) video memory (nonupgradable). Maximum resolutions
are 1024 x 768 pixels with 256 colors noninterlaced. In 800- x 600-pixel and

An integrated National Semiconductor PC87309 super input/output (I/O) control-
ler that controls the bidirectional parallel port, two serial ports, and the diskette
drive in the externally accessible front bay. The super I/O controller resides on the
ISA bus.
The parallel port can be set to operate in the following modes via the Parallel
Mode category in the System Setup program: output-only (AT-compatible), bi-
directional (Personal System/2 [PS/2]-compatible), or extended capabilities port
(ECP).

puter system interface (SCSI) host adapter that supports up to six 1-inch internal
SCSI hard-disk drives via a SCSI backplane board and special SCSI hard-disk drive
carriers. The SCSI backplane automatically configures SCSI identification (ID)
numbers and SCSI termination on individual hard-disk drives, greatly simplifying
drive installation.
Three SCSI backplane options include a non–hot-pluggable 2 x 2 backplane,
non–hot-pluggable 2 x 3 backplane, and hot-pluggable 1 x 6 backplane. The
hot-pluggable 1 x 6 backplane supports hot-pluggable SCSI hard-disk drive instal-
lation and removal. The integrated SCSI controller resides on the PCI local bus for
optimum performance.
