The T2885 was a desktop computer released by eMachines in 2003. The system board for this computer was the Intel D845GVSR Seabreeze Motherboard. The D845GVSR Motherboard has been discontinued by Intel. Replacements and upgrades are available from many online vendors. The T2885 is no longer available from eMachines, but it can be purchased used online.
Processors
The D845GVSR system board supported Intel Pentium 4 processors with 400 MHz or 533 MHz front side bus (FSB) speeds. The board also supported Intel Celeron Processors with FSB speed of 400 MHz. The socket type for the processors was mPGA478. According to eMachines, the T2885 came with the 2.8 GHz Intel Celeron Processor with 400 MHz FSB speed.
Chipset
The D845GVSR motherboard came with the Intel 845GV chipset. Three components of the 845GV chipset were: Intel 82801DB Input/ Output Controller Hub (ICH4), Intel 82845GV Graphics and Memory Controller Hub (GMCH) and a four megabit Firmware Hub (FWH).
Memory
Two slots for system RAM were located on the D845GVSR main board. The RAM slots supported 184-pin DDR SDRAM modules. The RAM speeds supported by this motherboard were DDR 333 (PC-2700), DDR 266 (PC-2100) or DDR 200 (PC-1600). The maximum supportable RAM for this system board was two 1 GB modules for a total of 2 GB of RAM. According to eMachines, the T2885 came with 512 MB of PC-2100 RAM.
Video/Audio
The on-board video card for the D845GVSR system board was the Intel Extreme Graphics Controller. This video card included 64 MB of dynamic graphics memory. The integrated audio for this motherboard was an two-channel audio subsystem for AC '97 with Realtek ALC202A codec. Audio interfaces included: ATAPI-type connectors for auxiliary line in and CD-ROM; front panel connectors for line out and microphone in; and back panel connectors for line in, line out and microphone in.
Input/Output Controller
The D845GVSR main board came with either a National Semiconductor PC87372 or an SMSC LPC47m172 Bus I/O Controller.
Interfaces
This system board included many ports, including: one parallel port, one serial port, six USB ports (two front and four rear), one 1.44 MB or 2.88 MB floppy disk drive interface and two IDE device interfaces with ATA-66, ATA-100 or Ultra DMA 33 support. PS/2-type mouse and keyboard ports, three fan connectors and one VGA monitor port were also included.
CMOS Battery
The system clock and CMOS memory for the D845GVSR board were powered by a 3.3-volt lithium coin cell battery (CR2032). The battery had a standby life of three years, which was extended by AC power to the computer. The system clock was accurate to within 13 minutes per year. The operational temperature of the clock was 25 degrees Celsius (77 degrees Fahrenheit).
Expansion
The D845GVSR motherboard had three PCI bus card connectors. These slots were available for user upgrades.
BIOS
The BIOS (basic input output system) for this board was Intel/AMI BIOS, which was located on the four megabit FWH. The Intel/AMI BIOS supported Plug and Play, SMBIOS and Advanced Configuration and Power Interface (ACPI).
Form Factor
The Intel D845GVSR Seabreeze Motherboard was a MicroATX form factor system board. The dimension were 9.2 inches by 8.2 inches (233.68 millimeters by 208.28 millimeters).
