microprocessor. The upgrade kit from Dell contains the correct version of the
microprocessor for use as a second microprocessor, as well as instructions for
performing the upgrade. The second microprocessor must have the same inter-
nal 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 mem-
ory 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.
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
640- x 480-pixel resolutions, 16.7 million colors are available for true-color
graphics.
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).
An integrated Adaptec AIC-7890 Ultra2/low-voltage differential (LVD) small com-
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.
