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.
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 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.
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.
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.
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).
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.
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.
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.
Chapter 6. System compatibility Software compatibility To maintain software compatibility, the interrupt polling mechanism that is used by IBM Personal Computer products is retained.
