3. New Features / Bugs Fixed
=============================

  * Performance improved
  * Fix BIOS compatibility problem when there is no PS/2 mouse


4. Device mapping order
========================

  The device mapping order in system is same as BIOS setting utility. The disk
  marked as "BOOT" will always be mapped as first SCSI disk. Please keep it in
  mind when installing Windows NT/2K/XP, otherwise OS may be installed to wrong
  location.

5. Known Problems
==================

  * Install OS to devices attached to HPT374 controller

    Before installing OS to devices attached to HPT374 controller, you must
    remove the drives connected to other controllers from your system temporarily.
    After OS installation complete, you can put them back.

  * Device driver update

    Since HPT374 UDMA/ATA133 RAID Controller is a dual-function PCI chip, when
    updating the driver, you must update it for both functions following their
    order as being shown in Windows device manager. 

  * Moving disks to other IDE controllers

    When you want to use disks previously attached to HPT374 controller on
    other IDE controllers, please first delete any array information on the 
    disks. Otherwise your data may be lost when you want to put it back later.

  * Rescaning disks

    There is a limitation for the refresh function in RAID Management Software.
    If you remove a disk from the controller but the software does not notice this
    event, it is also unable to notice the event when you plug another disk back
    to that location. You must force a refresh action before changing the disk.
