    • OS2KRNL provides all basic OS services, including tasking, memory management, etc.
    • OS2LDR provides most hardware-specific function, excluding memory management
  • Platform-Specific Drivers (PSDs) are drivers to provide SMP support on a bus-specific basis. Virtually all systems use the Intel APIC bus now, which is OS2APIC.PSD.
