TITLE:  Bravo LC P75/Adv!+5/75 Flash BIOS,v1.05
FILENAME(S) / PART NUMBER(S) / DESCRIPTION(S):
   05562037.EXE / 905562-037
   Bravo LC 4-66D System Flash BIOS, v1.05 

SUMMARY

   File 05562037.EXE contains Version 1.05, disk 1 
   of 1, of the Bravo LC P75 and Advantage!+ 5/75 system flash BIOS. 
   
    
   This update applies to the following systems: 503001 and 501798.

   
RESOLUTIONS

   Fixed timeout errors with Western Digital 2.1GB drives.   


ENHANCEMENTS

   Added support for system BIOS part number within BIOS.
   
   Added Advanced Power Management suspend support.
   
   Improved drive detection algorithm.   


PREVIOUS RELEASE(S)

   Version 1.04 is a special maintenance version and was developed 
   to resolve the problems described in Technical Bulletin #1365.  
   
   To resolve the problems, the level one cache was modified to 
   operate in write-through mode.  Because the performance of the 
   computer is reduced when using write-through cache, AST 
   recommends using version 1.03 (filename 05562035.EXE).  
      
   Use version 1.04 only if experiencing the symptoms described in 
   Technical Bulletin # 1365.
   
   
   Previous versions include the following resolutions:
   
   Sending the power down command to IDE drives.
   
   Assigning a conflict resource to serial ports if port 1 was set 
   to 2F8h or port 2 was set to 3F8h.
   
   System failing to boot due to an ISA VGA problem.
   
   Int 15h function returning incorrect memory size when the system 
   has more than 64MB.
   
   Unable to update ISA CMOS.
    
   ISA VGA problems that caused system to fail to boot.
   
   Changed serial port configuration options to support COM1 to COM4 
   on each port.  This fixed the problem of failing Win95 test.
   
   Previous versions also include the following enhancements:
   
   Set C8000-DFFFF to non-cacheable.
