Preface This Technical Information Manual provides information for the IBM PC 300GL Types 6268, 6278, and 6288. It is intended for developers who want to provide hardware and software products to operate with these IBM computers and provides an in-depth view of how these IBM computers work. Users of this publication should have an understanding of computer architecture and programming concepts.
When expressing storage capacity, MB equals 1 000 KB (1 024 000). The value is determined by counting the number of sectors and assuming that every two sectors equals 1 KB. Note: Depending on the operating system and other system requirements, the storage capacity available to the user might vary.

Chapter 2. System board features Chapter 2. System board features This section includes information about system board features. For an illustration of the system board, see “System board, types 6268, 6278, and 6288” on page 13. Celeron microprocessor with MMX technology PC 300GL Types 6268, 6278, and 6288 comes with an Intel Celeron microprocessor. The microprocessor, which has a heat sink attached, plugs directly into a connector on the system board.
Chapter 2. System board features System memory The system memory interface is controlled by the Intel 82810 chip set. PCI 100 synchronous dynamic random access memory (SDRAM) is standard. The maximum amount of system memory is 512 MB. For memory expansion, the system board provides two dual inline memory module (DIMM) connectors. 100 MHz DIMMs in sizes of 32 MB, 64 MB, 128 MB, and 256 MB are supported. The amount of memory preinstalled varies by model.
Chapter 2. System board features Delayed transaction PCI parity checking and generation support IDE bus master interface The system board incorporates a PCI-to-IDE interface that complies with the AT Attachment Interface with Extensions. The bus master for the IDE interface is integrated into the I/O hub of the Intel 810 chipset. The chip set is PCI 2.1 compliant. It connects directly to the PCI bus and is designed to allow concurrent operations on the PCI bus and IDE bus.
Chapter 2. System board features Video subsystem The video subsystem includes the Intel 810 graphics controller integrated in the Graphics Memory Controller Hub (GMCH) and 4MB of 100MHz local graphics display cache SDRAM. Graphics memory controller hub (Super Video Graphics Array) The video subsystem uses system memory for display buffer, commands, and 3D textures on AGP-enabled operating systems via Dynamic Video Memory Technology (DVMT).
Chapter 2. System board features The PC 300GL supports the following video subsystem modes: Figure 3.

Chapter 2. System board features Audio subsystem Some PC 300GL models come with an Analog Devices, Inc. integrated audio controller. These models, which are capable of playing and recording sounds, support DirectX and Microsoft Windows Sound System applications. SoundBlaster applications are supported in a DOS window only. The device drivers for the audio controller are on the hard disk drive. The device drivers are also available on the Software Selections CD provided with all models.

Chapter 2. System board features Connector panel Connectors for features that are integrated into the system board can be identified by a symbol directly below the connector. Connectors provided by an adapter might not have an identifying symbol. For pinout details on connectors, see Appendix A, “Connector pin assignments” on page 25.
Chapter 3. Physical specifications Chapter 3. Physical specifications This section lists the physical specifications for the PC 300GL Types 6268, 6278, and 6288. The PC 300GL has four expansion slots and four drive bays. Notes: The maximum altitude, 2133.6 m (7000 ft.), is the maximum altitude at which the specified air temperatures apply. At higher altitudes, the maximum air temperatures are lower than those specified. The PC 300GL computers comply with FCC Class B.
Chapter 3. Physical specifications PC 300GL — tower Dimensions Height: 383 mm (15.1 in.) Width: 192 mm (7.6 in.) Depth: 378 mm (14.9 in.) Weight Minimum configuration as shipped: 8.30 kg (18.3 lb) Maximum configuration: 10.2 kg (22.
Chapter 4. Power supply Chapter 4. Power supply The power supply requirements are supplied by a 145-watt power supply. The power supply provides 3.3-volt power for the system memory, Super I/O, and core chip set and 5-volt power for PCI adapters, the hard disk, and diskette drive. Also included is an auxiliary 5-volt (AUX 5) supply to provide power to power standby circuitry and a Wake on LAN adapter.
Chapter 4. Power supply Component outputs The power supply provides separate voltage sources for the system board and internal storage devices. The following figures show the approximate power that is provided for specific system components. Many components draw less current than the maximum shown. Figure 10. System board Supply voltage Maximum current Regulation limits +3.3 V DC 3000 mA +5.0% to −5.0% +5.0 V DC 4000 mA +5.0% to −4.0% +12.0 V DC 25.0 mA +5.0% to −5.0% −12.0 V DC 25.0 mA +10.
Chapter 4. Power supply Note: Some adapters and hard disk drives draw more current than the recommended limits. These adapters and drives can be installed in the system; however, the power supply will shut down if the total power used exceeds the maximum power that is available. Output protection The power supply protects against output overcurrent, overvoltage, and short circuits. See the power supply specifications on the previous pages for details.
Chapter 5. System software Chapter 5. System software This section briefly describes some of the system software included with the computer. BIOS The computer uses the IBM basic input/output system (BIOS), which is stored in flash electrically erasable programmable read-only memory (EEPROM). Some features of the BIOS are: PCI support according to PCI BIOS Specification 2.
Chapter 5. System software Configuration/Setup Utility program The Configuration/Setup Utility program provides menus for selecting options for devices, I/O ports, date and time, system security, start options, advanced setup, and power management. More information on using the Configuration/Setup Utility program is provided in PC 300GL User Guide. Advanced Power Management (APM) The PC 300GL computers come with built-in energy-saving capabilities.
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 Compatibility Report for a list of compatible hardware and software options. Hardware compatibility This section discusses hardware, software, 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 3. Sends the EOI 4. Waits one I/O delay 5. Enables the interrupt through the Set Interrupt Enable Flag command Hardware interrupt IRQ9 is defined as the replacement interrupt level for the cascade level IRQ2. Program interrupt sharing is implemented on IRQ2, interrupt hex 0A. The following processing occurs to maintain compatibility with the IRQ2 used by IBM Personal Computer products: 1. A device drives the interrupt request active on IRQ2 of the channel. 2.
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.
