Processor

The PowerMate P60 system uses a 64-bit, 60-MHz Pentium microprocessor. The processor has 16 KB of write-back internal cache, 8 KB for instructions and 8 KB for data. Integrated into the processor is a math coprocessor.

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

The special synchronous cache design uses 15-ns static random access memory (SRAM) that allows data to be sent or received from cache at the fastest possible bursts rate supported by the Pentium processor.

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

The processor is installed in a 273-pin, zero-insertion-force (ZIF) processor socket. This socket allows the installation of the next generation of Intel OverDrive processors based on the Pentium core (PGA type package).

Technical Information	1-5

Secondary Cache

The 16-KB primary cache (8 KB data and 8 KB instruction) is integrated into the processor. The system board also provides 256 KB of secondary cache, external to the processor. 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 considered 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 secondary is write-through. If the write is a cache hit, an external bus cycle is 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.

Flash ROM

Machine language programs are stored in a 28F001 Flash ROM known as the system's ROM BIOS. The system BIOS and video BIOS are contained in the ROM. The Flash ROM is 128 KB, which consists of 64 KB of system BIOS, and 32 KB of video BIOS.

The Flash ROM allows the BIOS to be upgraded with the BIOS Update utility without removing the ROM (see Section 4, Maintenance and Troubleshooting). The BIOS can only be reprogrammed by powering on the system with the BIOS Update utility diskette in drive A.

The BIOS programs execute the Power-On Self-Test (POST), update recovery code, initialize processor controllers, and interact with the display, diskette drives, hard disks, communication devices, and peripherals. The system BIOS also contains the Setup program and provides VGA controller support. The hardware setup default copies the ROM BIOS into RAM (shadowing) for maximum performance.

System BIOS is located in the upper portion of the Flash ROM and video BIOS in the lower portion. System BIOS is located between F0000h-FFFFFh and supports shadowing and shadowed memory. System BIOS is write protected and automatically enabled.

1-6 Technical Information

Video BIOS is located between C0000h and C7FFFh. The system memory map in shown in Table Section 1-3.

Flash ROM supports the reprogramming of the system and built-in video BIOS. A jumper on the system board is provided to prevent unauthorized changes to the BIOS. The factory default for the jumper is set to enabled, allowing the BIOS to be flashed. See Section 2 Setup and Operation, for jumper information. If the BIOS upgrade is interrupted see Section 4, Maintenance and Troubleshooting, for information on recovering the BIOS in the event of a catastrophic failure has occurred.

Power Management

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

When Power Management is enabled the computer automatically activates power-saving features and enters a sleep mode whenever inactivity is sensed. The computer's powersaving functions are as follows.

nReduces the CPU clock speed

The CPU, cache, and video clock speeds are reduced, putting the computer in sleep mode.

Technical Information	1-7

nBlanks out the monitor

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

nForces 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.

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 Section 1-5.

System Memory

The system comes standard with 8-MB of memory. System memory can be expanded up to 80 MB for the desktop system and up 136 MB for the minitower system. Memory expansion is performed using single in-line memory modules (SIMMs) installed in SIMM sockets.

The standard 8 MB of memory is soldered on the system board. The first megabyte includes the standard 640 KB of base memory. The remaining memory is extended memory. Four SIMM sockets are integrated on the system board.

The SIMM memory sockets accept 1-, 2-, 4-, 8-, 16-, or 32-MB SIMM sticks. High-speed RAM is 32 bits wide with four parity bits. SIMMs are 256 K x 36 bit (1 MB), 512 K x 36 bit (2 MB), 1 M x 36 bit (4 MB), 4 M x 36 bit (16 MB), and 8 M x 36 bit (32 MB). There are no switches or jumpers to set when SIMMs are added.

Technical Information	1-9

The system board's four SIMM sockets are assigned as banks A and B. Each SIMM kit is inserted into a pair of sockets or bank. Bank A consist of sockets J28 and J27, and in the desktop version can only accommodate low profile (1-, 2-, and 4-MB) SIMM sticks. Bank B consist of sockets J25 and J26. Different size SIMMs cannot be intermixed

within a bank. See Section 3, Options, for installation instructions and SIMM memory configurations.

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 listed in Table Section 1-7. Interrupt-level assignments 0 through 15 are in order of decreasing priority. See Section 2, Setup and Configuration, for information on changing the interrupts using Setup.

Video Controller

The Cirrus Logic CLDG5434 PCI graphics controller combines powerful elements aimed at addressing the requirements of personal computer designs. State of the art techniques have been added for optimizing performance in computer graphic intensive applications and graphical user interfaces (GUI). A variety of industry standard 32-bit PCI-bus interfaces are integrated on chip. The key is that PCI-bus interfaces are 32-bit wide.

Included in the video controller are cost saving features such as an integrated palette DAC and clock synthesizer along with integrated support for multiple bus interfaces and flexible DRAM-based display memory configurations.

The TrueColor RAMDAC provides 24-bit true color. The integrated dual clock synthesizer allows full programmability of MCLK (memory clock) and PCLK (pixel clock). The integrated clock synthesizer supports frequencies from 390 kHz to 120 MHz. The CLDG5434 supports up to 2 MB of display memory. The video memory is 256K x 16 DRAM.

The VESA display power management signaling (DPMS) standard is supported, enabling stand-by, suspend, and off power saving modes. This includes the ability to independently stop HSYNC of VSYNC and hold them at a static level. Additionally the RAMDAC may be powered-down and the clock frequencies lowered for further power savings. Color Key and video overlay are supported.

Video Memory

The 1 MB of on-board video DRAM is expandable to 2 MB and provides graphic resolutions of or 640 x 480 with 16.8 million colors, 800 x 600 with 64K colors, 1024 x 768 with 256 colors, or 1280 x 1024 with 16 colors.
