PSD stands for "Platform Specific Driver". These drivers provide an abstraction layer for the underlying hardware by allowing the operating system to call generic functions to perform platform-specific operations without worrying about the actual hardware implementation.

If multiple PSD statements are encountered, OS/2 will load each PSD in the order listed in CONFIG.SYS, and call the PSD's install function. The first PSD which successfully installs will be the one OS/2 uses.

PSD statements are processed before BASEDEV, IFS, and DEVICE statements.

ACPI.PSD - ACPI platform-specific driver

ALR.PSD

Advanced Logic Research (ALR)

PSD=ALR.PSD

CAVERUN.PSD

IBM PC Server 720

PSD=CAVERUN.PSD

OS2APIC.PSD

OS2PCAT.PSD

OS4APIC.PSD

This is a component part of the OS/4 Kernel project.

Parameters:

/APIC

To route IRQ through IOAPIC. Use the /APIC option switch only when PRELOAD is set in the os2ldr.ini file. If this switch is not used then the PIC mode is set and the IRQ will be routed through PIC.

PROLIANT.PSD

Compaq Proliant 2X00 or Proliant 4X00 Server

PSD=PROLIANT.PSD

TRICRD.PSD

Tricord

PSD=TRICRD.PSD

V1_EBI2.PSD

PSD=V1_EBI2.PSD

VIPERMP.PSD

PSD=VIPERMP.PSD

WYSE.PSD

Wyse

PSD=WYSE.PSD
