BIOS 1.00.07.BT0 Morrison32 Release 7.0

Features/Errata Fixed In This Release:

o Fixed problem where setup could disable primary or secondary
  channels but wouldn't free up the corresponding resources for PCI 
  usage. 

o Added code to implement PCI enumeration for PIIX devices.

o Updated IRQ routing information such that onboard devices are
  tagged for IRQ routing reasons.  Added PIIX IDE routing entry. 
  Utilized the new onboard routing bit tag to allocate onboard IRQs.

o Removed PIIX IDE from protected device procedure so it could be
  configured as a PCI device.

o Removed PIIX IDE device nodes.

o Added second structure to support multiple PIIX revision IDs.

o PIIX configured to not hide its multifunction capability.

o Removed PIIX IDE devnode references.

o Move IRQ 12 in IRQ priority allocation list so mouse IRQ not 
  given away prematurelly.

o Changed to prevent incorrect operation of IRQs selected/deselected.
  Proper Operation: No more than one IRQ should be "not effective" 
  (greyed and unselectable) at any one time and this IRQ  must be set
  to "available". If upon entering this screen, no IRQ is set to 
  available, one IRQ will be changed from "Used by ISA" to "Available" 
  and made not effective. IRQ 12 is an exception. IRQ 12 can never be
  the only IRQ set to "Available".

o Added support of scanning user flash area.

o Added Scan User Flash Area option in the Boot Options setup menu.
