Processor and Secondary Cache

The PowerMat e P r ofessional uses a Pentium II processo r with an internal clock speed of 233 MHz or 266 MHz. The external speed of the 233-MHz and 266-MHz processors is 66 MHz.

Each processo r has 32 KB of write-back primary cache and a math coprocesso r . The 32-KB primary cache provides 16 KB for instructions and 16 KB for data.

The processor is an advanced pipelined 32-bit addressing, 64-bit data pro cesso r designed to optimize multitasking operating systems. The 64-bit registers and data paths support 64- bit addresses and data types.

To use t he Pentium II processor’s power, the system features an optimized 64-bit memory interface and 512 KB of secondary write-back cache incorporated into the processor.

The processor is compatible with 8-, 16-, and 32-bit software written for the Intel386™, Intel486™, Pentium, and Pentium Pro processors. The Pentium II processor is contained on a Single Edge Contact (S . E.C.) cart r idge that plugs into the system board at Slot 1, which is a 242-pin edge connector. The processo r subsystem consists of the following components:

processo r car d ( including the processor and seco ndary cache)



t hermal plate



back cover.

When the processo r subs yst em is mou nted in Slot 1, it is secured b y a r et ention mecha nism (RM) attached to the system board. The RM acts as an insertion guide and prevents movement of the pro cessor after installation. The processor heatsink is also stabilized by supports that attach t o the motherboard.

System BIOS

The system BIOS is from Intel/American Megatrends Incorporated (AMI) and provides ISA a nd PCI compatibility. The BIOS is contained in a 2- MB flash memory d evic e on the system board. The BIOS provides the Power- On Self Test (POS T), the system Setup pro gr am, a PCI and ID E auto -configuration ut ility, an d BIOS recovery co de.

The system BIOS is always shadowed. Shadowing allows any BIOS rout ine to be executed from fast 32-bit onboard DRAM instead of from the slower 8-bit flash device.

NEC’s Flash ROM allows fast, econo mical BIOS upgrades. NEC Flash ROMs are reprogrammable system and video EP ROMs. With NEC’s Flash ROM, a ROM BIOS change is expedited in the following ways:



is fa st and easily done usin g a F lash utilit y



eliminates the ex pen sive replacement of ROM BIOS chips, and reduces system maintenance costs

1-8 Technical Information

reduces inadvertent system board damage that can take place when replacing



ROMs facilitates adop ting new technology while maintain ing corp orate st andards



gives network administrators company-wide control of BIOS revisions.



The BIOS programs execute the Po wer - On Self-Test, initialize processo r controllers, and interact with the display, diskette drives, hard disks, communication devices, and peripherals. The syste m BIOS also conta in s the Setu p utility. The hardware setup default copies the RO M BIOS into RAM (sh adow ing) fo r max imum perf ormance.

The Flash ROM allows the system and video BIOS to be upgraded with the BIOS Update utility, witho ut remo v ing the ROM (see Sect ion 2 for further in formation on the BIOS Updat e utility) . The Flas h ROM supports the repro gr ammin g of t he s yst em BIOS an d the video BIOS.

System Memory

Configurations ship with 32 MB or 64 MB of memory: 640 KB of base memory and 31 MB or 63 MB of extended memory. System memory can be expanded up to 256 MB using opt ional single in-line memory modules (SIMMs) installed in SIMM sockets on the system board.

The memory configuration consists of two banks (bank 0 and bank 1) with two so ckets each. The memory sockets accept 32-bit, 60-ns for faster, 4- , 8- , 16- , 32-, or 64- MB SIMMs. The sockets accept E xtended Data Out ( EDO) mode or Fast Page (FM) mode SIMMs and support par ity, non-parity, or error checking and correction (ECC).

The SIMMs are 1 MB x 32 bit (4 MB) , 2 MB x 32 bit (8 MB), 4 MB x 32 bit (16 MB) , 8 MB x 32 bit (32 MB), and 16 MB x 32 bit (6 4 MB). When the standard SIMMs are removed, four 64-MB SIMMs may be installed for a t otal of 256 MB.

CAUTION:

SIMMs must match the t in metal plating used on the system board SIMM sockets. When adding SIMMs, use tin-plated SIMMs only.

Technical Information 1-11

SIMMs install directly in the four sockets on the system board. T he four sockets are assigned as Bank 0 (2 sockets) and Bank 1 (2 sockets) . All configurations have two SIMMs insta lled in Ba nk 1.

SIMMs must be installed in pairs of the same memory type and size. Both so ck ets must be populated within a bank for t he system to wo r k . No switch or jumper settings are required when the memory is changed. The system BIOS auto matically detects the SIMMs. See “Checking the Memory in the System” in Section 3 for the valid configurations.

Interrupt Controller

The interrupt controller operates as an interrupt manager for the entire system environment. The controller accepts requests from peripherals, issues interrupt requests t o the processor, resolves interrupt priorities, and provides vectors for the processor to deter mine which interrupt routine to execute. The interrupt cont r oller has priority assignment modes that can be reconfigured at any time during system operations.

The interrupt levels are described in Table 1-5. Interrupt- level assignments 0 through 15 are listed in order of decreasing priority. See Section 2, “Setup and Operation,” for information on changing the interrupts using Setup.

* These interrupts are selected and used by the installed expansion boards.

Plug and Play

The system comes with a Plug and Play BIOS that supports Plug and Play technology. Plug and Play eliminates co mplicat ed setup proce dures fo r ins talling Plug an d Play expan sio n boards. With Plug and Play, adding a Plug and Play expansion board is done by turning off t he system, insta lling the board, an d turning on t h e system. There are no jumpers to s et and no system resource conflicts to r esolve. Plug and Play automatically configures the board.

ISA Bus

The system board uses t he IS A bus for t r ansferring data between the processor and I/O peripherals and expansion boards. The ISA bus supports 16-bit data transfers and typically operat es at 8 MHz. ISA expansion slot connector pin assignments are provided in Appendix A.

PCI Local Bus

The 32-bit PCI-bus is the primary I/O bus for the system. The PCI-bus is a highly integrat ed I/O interface that offers the highest performance local bus available for the Pentium II processor. T he bus support s burst modes that send large chunks of data across the bus, allowing fast displays of hig h-resolutio n images.

Th e hig h-band width PCI- b us eliminate s t he d ata bott lene ck fou nd in trad itional syste ms, maintains maximum performance at high clock speeds, and provides a clear upgrade path to future technologies.

PCI expansion slot connector pin assignments are provided in Appendix A.

Technical Information 1-13

PCI/IDE Ports

The system board pro vides two high-performance PCI/IDE ports: a primary channel and a secondary channel. Each port suppo r ts up to t wo devices for a total of four IDE devices. The primary PCI/IDE port has an enhanced IDE interface that supports PIO Mode 4 devices with 16 MB per second 32-bit wide data transfers on the high-performance PCI local bus. The installed hard disk drive is connected to the primary PCI/IDE port. In multimedia configurations, the installed CD-ROM reader is connected to the seco ndary PCI/IDE port.

Parallel Interface

The system has a 25-pin parallel bidirectional enhanced parallel port on the system board. Port specifications conform to the IBM-PC standards. The port supports Enhanced Ca pab ilities P ort (E CP) and Enhanced Parallel Por t (EPP) modes for dev ices that require ECP or EPP protocols. The protocols allow high-speed bidirectional transfer over a parallel port. This increases parallel port functionality by supporting more devices.

The BIOS has automatic ISA printer port sensing. If the BIOS detects an ISA printer port mapped to the same address, the built-in printer por t is disabled. The BIOS also sets the first parallel interface port it finds as LPT1 and the second port it finds as LPT2. The interrupt is selected to either IRQ5 or IRQ7 via Setup. Software- selectable base addresses are 3BCh, 378h, and 278h.

I/O addresses and interrupts for t he parallel port are given in Table 1-6.

NOTE:

Any interrupts used for the built-in parallel p ort are not available fo r I SA paralle l ports.

Parallel interface signals are output through the system board’s 25-pin, D-subconnector . This connector is located at the rear of the system unit. Pin locations for the parallel interface connector ar e given in Appendix A.

1-14 Technical Information

Serial Interface

The system has two 16C550 UART-compatible serial ports (COM1 and COM2) integrated on the I/O cont r oller. The serial ports suppo rt the standard RS-232C interface and the IR interface (see Table 1-7). The buffered high-speed serial ports suppor t transfer rates up to

19.2 KB. These port s allow the installation of high-speed serial devices for faster data transfer rat e s.

I/O addresses and interrupt levels for the two channels are given in Table 1-7. The interrupt level is selectable via Setup to either IRQ3 or IRQ4. S oftware selectable base addresses are 3F8h, 2F8h, 3E8h, and 2E8h.
