The following sections give an overview of the systems. Differences between systems are noted as they occur.

SYSTEM CHASSIS

The chassis provides an enclosure for system controls, system board, power supply, five expansion board slots, a six-connector PCI/ISA backboard, and six storage device slots. The PCI/ISA backboard has three 8-/16-bit ISA connectors and three 32-bit PCI connectors. Two ISA connectors and two PCI connectors are dedicated. The remaining ISA and PCI connectors are shared, meaning their usage is limited to one or the other but not both.

The six storage device slots support up to four accessible devices and two internal hard disk drive devices. The four accessible devices include the standard one-inch high 3 1/2-inch 1.44-MB diskette drive, a standard CD-ROM reader, and, in some 2516 models, an Iomega 100i Zip drive. One of the two internal drive slots holds the standard 1-inch high 3 1/2-inch hard disk drive. The other internal drive slot is for an optional 1-inch high 3 1/2-inch hard disk drive.

Processor

The PowerMate Office computers use the following Pentium processors:

T133-MHz processor with an internal speed of 133 MHz and an external speed of 66 MHz (2513 models)

T166-MHz processor with an internal speed of 166 MHz and an external speed of 66 MHz (2516 models).

Each processor has 16 KB of write-back primary cache and a math coprocessor. The 16KB primary cache provides 8 KB for instructions and 8 KB for data.

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

To use the Pentium processor’s power, the system features an optimized 64-bit memory interface and complementary asynchronous 256-KB secondary cache.

The processor is compatible with 8-, 16-, and 32-bit software written for the Intel386™, Intel486™, and Pentium processors.

To accommodate future technologies and work requirements, the Pentium processor comes in a 321-pin zero insertion force (ZIF) socket. The socket provides an upgrade path to the next generation processor.

Secondary Cache

All models contain 256 KB of asynchronous secondary cache on the system board, external to the processor. The cache uses 15-ns SRAM that allows data to be sent or received from cache with one wait state burst. Cache memory improves read performance by holding copies of code and data that are frequently requested from the system memory by the processor. Cache memory is not part of the expansion memory.

The cache is connected directly to the processor address bus and uses physical addresses. A bus feature known as burst enables fast cache fills. Memory areas (pages) can be designated as cacheable or non-cacheable by software. The cache can also be enabled and disabled by software.

The write strategy of the cache (primary and secondary) is write-back. If the write is a cache hit, an external bus cycle is not generated and information is written to the cache. Any area of memory can be cached in the system. Non-cacheable portions of memory are defined by software. The cache can be cleared by software instructions.

Technical Information 1-11

System and Video BIOS

The system and video BIOS are stored in a 1 MB (128 KB by 8) flash memory device (Flash ROM). The system BIOS uses 64 KB, the video BIOS uses 32 KB, and 32 KB is reserved. The system BIOS is capable of being shadowed and cached through the system’s Setup utility (see Section 2, “Setup and Operation,” for setup information). The System BIOS is write protected and automatically enabled.

The BIOS programs execute the Power-On Self-Test, initialize processor controllers, and interact with the display, diskette drives, hard disk drives, communication devices, and peripherals. The system BIOS also contains the Setup utility. The hardware setup default copies the ROM BIOS into RAM (shadowing) for maximum performance.

The Flash ROM allows the system and video BIOS to be upgraded with the BIOS Update utility, without removing the ROM (see Section 2 for further information on the BIOS Update utility). The Flash ROM supports the reprogramming of the system BIOS and the video BIOS.

The system memory map is shown in Table 1-4.

1-12 Technical Information

Power Management

Each system incorporates power management features that lower power consumption when there is no activity detected from the keyboard, mouse, diskette drive, CD-ROM reader, or hard disk drive after a pre-defined period of time. As soon as activity is detected the system resumes where it left off.

With Power Management enabled, the system automatically activates the power-saving features and enters Suspend mode when prolonged inactivity is sensed. The system’s power-saving functions are as follows.

TReduces CPU clock speed

The CPU, cache, and video clock speeds are reduced, putting the system in the Suspend mode.

TBlanks out the monitor

Puts the video controller into Suspend mode. The vertical sync clock and blank signals to the monitor are disabled.

TForces the IDE devices into stand-by mode

A suspend command is sent to the IDE devices which put the devices into a stand-by mode.

The automatic polling feature in Windows® 95 keeps the system from automatically entering power management. For automatic power management, the auto insert notification must be disabled.

I/O Addressing

The processor communicates with I/O devices by I/O mapping. The hexadecimal (hex) addresses of I/O devices are listed in Table 1-5.

System Memory

The PowerMate Office 2513 model and some 2516 models come standard with 16 MB of memory: 640 KB of base memory and 15 MB of extended memory. Some PowerMate Office 2516 models come standard with 32 MB of memory: 640 KB of base memory and 31 MB of extended memory. System memory can be expanded up to 128 MB, using optional single in-line memory modules (SIMMs) installed in SIMM sockets on the system board.

Four SIMM sockets are integrated on the system board. The 16-MB systems ship with two 8-MB SIMMs. The 32-MB system ships with two 16-MB SIMMs. All systems ship with 60-ns tin-plated EDO SIMMs.

The SIMM memory sockets accept 32-bit (non-parity) 4-, 8-, 16-, or 32-MB SIMMs. The SIMMs are 1 MB x 32 bit (4 MB), 2 MB x 32 bit (8 MB), 4 MB x 32 bit (16 MB), and

8 MB x 32 bit (32 MB). When the standard SIMMs are removed, four 32-MB SIMMs may be installed for a total of 128 MB.

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

SIMMs install directly in the four sockets on the system board. The four sockets are assigned as SIMM 1 through SIMM 4. The two standard SIMMs (8 MB or 16 MB) are installed in SIMM 1 and SIMM 2. SIMMs must be installed in pairs of the same memory type. Jumpers are not required to set memory size or type, as the system BIOS automatically detects the SIMMs. SIMM 1 and SIMM 2 must always be filled for the system to operate. Table 1-6 shows the SIMM memory upgrade path.

Interrupt Controller

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

The interrupt levels are described in Table 1-7. Interrupt-level assignments 0 through 15 are in order of decreasing priority. See Section 2, “Setup and Operation,” for information on changing the interrupts using Setup.
