• 48-Bit LBA – Logical block Addressing. 28-bit LBA allows the use of hard drives up to 137 GB. 48-bit LBA
allows the use of hard drives significantly over 137 GB. For more information see

• APM/APCI – APM (Advanced Power Management) is a legacy power management scheme that was first widely
supported in Microsoft® Windows® 95. Most of the interesting functionality for APM is in a machine-specific
BIOS that is hidden from the operating system. APM is a legacy solution that has been superseded by ACPI
(Advanced Configuration and Power Interface), which is the robust scheme for power management and system
configuration supported in the Windows 98 and Windows 2000 family of operating systems. Windows XP uses
ACPI. For more information see:

• APIC – an advanced programmable interrupt controller (APIC) scheme used by all PCs currently in production. It
consists of a local APIC which delivers interrupts to a specific processor and an I/O APIC which collects interrupt
signals from I/O devices and sends messages to the local APICs when those devices need to interrupt. Each I/O
APIC has an arbitrary number (typically 24) of interrupt inputs. For more information see:

• BIOS – Basic Input/Output System: The system’s firmware which allows the power up of various devices during
boot for the OS to load properly.
• HP – means that these device drivers are available from the HP Web site:
http://h18007.www1.hp.com/support/files/index.html
• HP/WU – means that drivers are available from both the HP Web site (Softpaq) and from Windows Update. HP
has tested and validated that the device drivers on the HP Web site function as expected with the operating
systems that are listed as supported in Table 3 Operating System Support Definitions.
• HPQFlash – HPQFlash is a BIOS update utility used from within Windows from Hewlett-Packard that updates the
read-only-memory (ROM) chip on the system board.
• N/R – means "not recommended."
• OS – means that support is included with the operating system.
• PIC – A programmable interrupt controller (PIC) scheme first used in the IBM PC/AT from the 1980s that used two
Intel 8259 programmable interrupt controllers. Each 8259 had eight interrupt inputs (IRQs). The second interrupt
controller was connected to the first interrupt controller leaving fifteen interrupt inputs available for all devices in a
PC.
• ROMPAQ – ROMPAQ is a BIOS update utility on a bootable diskette from Compaq (now Hewlett-Packard) that
updates the read-only-memory (ROM) chip on the system board.
• SP – Service Pack
