TECHNICAL INFORMATION - Niagara NT 928LD
Pentium II, SLOT 1 System Board for professional applications
Contact Sales:
| Processor,Cache (L1),Co-Processor |
Pentium II processor, optimized on an adapter card using the slot 1 configuration, rated at speeds of 233 - 400MHz. Superb throughput and stable performance characteristics under Windows NT or other 32-bit pre-emptive, multi-tasking operating systems like OS/2 or Unix. Math co-processor support is provided internally by processor. |
|||
| Secondary Cache (L2): |
On the adapter card, limited by Intel proprietary tag RAM, to a maximum of 256 or 512 Kilobytes of burst pipelined asynchronous SRAM. |
|||
| Memory Configuration |
Four banks of 64/72-bit wide SDRAM, for a total of 512Megabytes of storage. Simple user upgrading can be achieved with modules of 1M, 2M, 4M, 8M, 16M, 32M, 64M, 128Megabyte architecture. |
|||
| PCI Interface | Supports four (4) bus masters and is 2.1 compliant at 33 Mhz bus speed. Also features three (3) ISA slots and an AGP socket. | |||
| ASIC |
82440LX PCI with AGP support. |
|||
| Interfaces |
Features: two 16550 UART serial RS232 ports, supporting 115.2Kbaud transfer rate for fast modems and communication. USB ready. One Centronics/AT Bi-Directional IEEE128 enhanced parallel port, which can be configured as LPT1, LPT2, LPT3. Floppy controller supports 2 drives of 360K, 720K, 1.2M, 1.44M, or 2.88Mbyte capacity. Its digital data separator (Phase Lock Loop) circuit supports transfer rates of up to 1 Mb/sec for increased performance and greater reliability. All on board ports can be configured for COM, IRQ or disabled in BIOS, thus facilitating easy system installations. |

Raid Ready Port |
Slot provides hardware assisted interface to Adaptec's model ARO 1130 Raid adapter with the on-board SCSI interface providing Bus master DMA, 133Mbyte/se Burst transfer rate of data, Raid level: 5, 1, 0, 0/1. | |||
| Integrated Features |
PS/2 mouse port. Battery backed real time clock. Combined feature connector for a single case connection to speaker, keylock, reset, turbo LED, IDE LED, SCSI LED. |
|||
| Operating Systems: | MS/DOS, Windows 3.1x, Windows 95, Windows NT, NT Workstation, OS/2, Unix and others. | |||
| Cardedge Connections: | PS/2 mini DIN, PS/2 mouse, two serial, 1 parallel, two USB (optional). | |||
| BIOS |
2 Megabyte Flash. Phoenix, Award, AMI, M.R.Bios. |
|||
| Video | Not provided on board. But superb video acceleration is achieved with either one of our fastest "NT 4 or NT 100 series" on PCI bus adapter cards or optional AGP port card. Propelled by our 300 mips RISC processors they are ideally stable for up to 16 million colours, suited for acceleration of Windows, Spreadsheets, CAD and Paint Programs. | |||
| Fabrication Type | Canadian, worst case conditions, designed and manufactured as a 6-layer printed circuit board. Mania Netlist tested, UL approved. Hand tracked for best possible electrical characteristics with special attention to capacitance tolerance. Solid ground plane and powerplane for electrical stability. Standard .008/.008 inch track to space dimensioning provides efficient and reliable design. Liberal use of decoupling capacitors minimizes excessive current over- or undershoots. Strip-line technique used on high speed signals. Extensive use of Surface Mount Technology offers high reliability, durability and improved thermal characteristics as proven with our "GREEN" or "Energy Star" low power attributes. Shielding of high speed signals and good lay-out practices were employed, aiding in passing EMI/EMC tests for various countries, such as FCC CFR 47 part 14 Subpart J, VDE Class B test, 0871 Level B. | |||
| Military | In addition to our industrial quality, even higher standards can be met by separate process control.
