BIOS - Change V4.06 Release 1.04.1141/1156
==========================================

Cause of Change:
----------------

- Fix for problems with modem communication. 

- Changed default value for LBA Translation Mode 
  from PTL to LBA.

- New microcode updates for Intel Katmai and 
  Coppermine and Deschutes.

- Changed P6 Update failure BIOS error message into:
  "Patch for installed CPU not loaded. Please run 
   the BIOS flash update diskette."

- Added some IODELAYs in physical port-io for ISA-PNP 
  and a better analysis of PNP-status register. 
  Without this fix the System hangs sporadically if some 
  soundcards (Genius3DX2,SB Audio PCI 64V) are plugged in.

- Microcode patches updated. Now also PGA Celeron 
  processors used with a Slot 1 CPU converter board 
  were supported.

- The DMA-capable-bits for IDE are now set correctly for 
  IDE master and slave. Windows-NT will now use DMA-modes 
  if the drives can support DMA and/or Ultra-DMA.
