Notes:

AG56: Not a Plug 'n Play BIOS. Should be programmed into EPROM or other brands of flash memory (not SST nor Winbond).

    AG56S: A Plug 'n Play BIOS.  Should be programmed into SST or Winbond
           Flash Memory.  This BIOS should be used for Windows 95 certifi-
           cation. Does NOT support PS/2 mouse!

Note: AG56P BIOS is a Plug 'n Play BIOS, and has to be used with SST or Winbond Flash Memory. If this BIOS is programmed in EPROM or other brands of Flash Memory (not SST nor Winbond), there will be a problem with Windows 95 RESTART function. Supports PS/2 mouse
