Change History:
1. Update new VGA BIOS.
2. Add sleep trap method for LCD power off sequence during entering S4.
3. Fix the system hang after resume from S4 and then enter S3 with 
    USB controller disabled in device manager.
4. Update EC BIOS.

To flash in Windows mode, pls install Winflash utility as in Winflash.zip.
To flash in pure DOS mode, pls run: PHLASH16 xxx.WPH /mode=3 /S

P.s.
If you're using DOS bootable floppy (w/o himen.sys) created in Windows XP, 
you will get an error like "can't present memory manager" while you 
update the BIOS (ie himen.sys)

You may do either one of the two ways to resolve:
1. press F5 to bypass himem.sys 
2. modify the parameter from /S to /X 

The parameter  /X  for PHLASH is "Ignore XMS memory manager check".
The parameter /S PHLASH is "Silent operation (Turn off speaker)".
