Chapter 2. System Board Features Chapter 2. System Board Features This section includes information about system board features. To view an illustration of the system board, see “System Board” on page 14. For a list of features provided with the PC 365, see “Hardware Features” on page 1. Microprocessor The primary microprocessor in the PC 365 is the Intel P6, called the Pentium Pro. A voltage regulator circuit on the system board provides the required power for the primary microprocessor.
Chapter 2. System Board Features Chip Set Control The PC 365 uses the second-generation Intel 82440FX chip set. This chip set provides a bridge between the peripheral component interconnect (PCI) bus and the microprocessor bus. (For information on the PCI bus, see “PCI-to-ISA Bridge” on page 6.) Also, this chip set controls the system memory interface. The PC 365 also uses the PIIX3 chip.
Chapter 2. System Board Features PCI-to-ISA Bridge The PIIX3 chip provides the bridge between the peripheral component interconnect (PCI) and industry standard architecture (ISA) buses. The chip is used to convert PCI bus cycles to ISA bus cycles. The PCI bus is compliant with PCI Local Bus Specification 2.1. The PCI bus runs synchronously to the host bus and is driven at a frequency of 30 or 33 MHz, depending on the speed of the microprocessor bus (60 MHz or 66 MHz). The ISA bus operates at speeds of 7.
Chapter 2. System Board Features Bus Master EIDE Interface The system board incorporates a PCI bus master, enhanced integrated drive electronics (EIDE) interface that complies with AT Attachment Interface with Extensions; this allows concurrent operations on the PCI and EIDE buses. The subsystem that controls internal devices is integrated with the EIDE interface. Up to four IDE devices can be attached to the system board through a ribbon cable that connects to one of two connectors on the system board.
Chapter 2. System Board Features USB Interface Universal serial bus (USB) technology is a standard feature of the computer. The system board provides the USB interface with one connector. A USB-enabled device can be attached to the connector, and if that device is a hub, multiple peripheral devices can be attached to the hub and be used by the system. The USB connector uses Plug and Play technology for installed devices. The speed of the USB is up to 12 Mb/second with a maximum of 255 peripheral devices.
Chapter 2. System Board Features Input/Output Controller Control of the integrated input/output (I/O) ports and diskette drive is provided by a single chip, the National Semiconductor PC87308. This chip, which is compatible with Plug and Play ISA Specification 1.
Chapter 2. System Board Features Infrared Port Two UART serial ports are integrated into the system board. One of these ports is configured into an infrared port. When an optional infrared module is attached to the port, the computer is capable of transmitting and receiving wireless communications with other infrared-enable devices. The infrared module plugs directly into the infrared port and provides a link of up to one meter. The infrared port uses any of the same four assignments as the serial port.
Chapter 2. System Board Features Keyboard and Mouse Ports The keyboard-and-mouse subsystem is controlled by a general purpose 8-bit microcontroller. The controller consists of 256 bytes of data memory and 2 KB of read-only memory (ROM). The controller has two logical devices; one controls the keyboard, and the other controls the mouse. The keyboard has two fixed I/O addresses and a fixed IRQ line and can operate without the mouse.
Chapter 2. System Board Features Real-Time Clock The real-time clock is a low-power clock that provides a time-of-day clock and a calendar. The clock settings are maintained by an external battery source of +3 volts. The system uses 242 bytes of memory to store complementary metal-oxide semiconductor (CMOS) memory. Moving a jumper (J8) on the system board erases CMOS memory. To locate the battery or J8, see “System Board” on page 14.
Chapter 2. System Board Features Riser Card The system board uses a riser card for expansion. The riser card plugs into the system board, and adapters plug into the ISA-expansion or PCI-expansion connectors on the riser card. Signals from adapters are routed to the ISA or PCI buses. Each ISA-expansion connector provides a 16-bit-wide data path; each PCI-expansion connector provides a 32-bit-wide data path. Each PCI-expansion connector is capable of driving one low-power Schottky load.

Chapter 6. System Compatibility Chapter 6. System Compatibility This chapter discusses some of the hardware, software, and BIOS compatibility issues for the computer. Refer to PC 365 System (Type 6589) Compatibility Report for a list of compatible hardware and software options. Hardware Compatibility This section discusses hardware and BIOS compatibility issues that must be considered when designing application programs. Many of the interfaces are the same as those used by the IBM Personal Computer AT.
Chapter 6. System Compatibility Hardware Interrupts Hardware interrupts are level-sensitive for PCI interrupts and edge-sensitive for ISA interrupts. The interrupt controller clears its in-service register bit when the interrupt routine sends an End of Interrupt (EOI) command to the controller. The EOI command is sent regardless of whether the incoming interrupt request to the controller is active or inactive. The interrupt-in-progress latch is readable at an I/O-address bit position.
Chapter 6. System Compatibility Diskette Drives and Controller The following tables show the reading, writing, and formatting capabilities of each type of diskette drive. Table 37. 5.25-Inch Diskette Drive Reading, Writing, and Formatting Capabilities Diskette Drive Type 250/500 KB Mode 300/500 KB Mode 1 MB Mode Single sided (48 TPI) RWF — — Double sided (48 TPI) RWF RWF — High capacity (1.2 MB) RWF RWF RWF Table 38. 3.
Chapter 6. System Compatibility Software Compatibility To maintain software compatibility, the interrupt polling mechanism that is used by IBM Personal Computer products is retained. Software that interfaces with the reset port for the IBM Personal Computer positive-edge interrupt sharing (hex address 02Fx or 06Fx, where x is the interrupt level) does not create interference. Software Interrupts With the advent of software interrupt sharing, software interrupt routines must daisy-chain interrupts.
