- ## AMIsetup EISA configuration file
- ##
- ## *************** Copyright (C) 1993 Robert Muchsel *******************
- ##
- ## This file is needed by AMIsetup to access EISA NVRAM properly.
- ## PLEASE DO NOT DELETE THIS FILE!
- ##
- ## If you are a hardware wizard, you may want to add more chipsets to
- ## this file. If you're not, HANDS OFF!
- ##
- ## AMIsetup understands the following commands:
- ##
- ## OFF
- ## - disables EISA NVRAM access
- ## DETECT
- ## - tries to detect the EISA NVRAM port at the given addresses
- ## (more than one DETECT line possible)
- ## SET
- ## - sets the EISA NVRAM port to a given value without trying to detect
- ## the correct port (may help you in case of an error)
- ##
- ## Syntax of DETECT/SET:
- ##
- ## DETECT/SET LO,HI,OFFSET,CHECKSUM,1S,1E,2S,2E,3S,3E,4S,4E
- ## LO : Index port low byte
- ## HI : Index port high byte
- ## DATA : Data port
- ## OFFSET : Offset of setup values in NVRAM
- ## CHECKSUM : Offset of (word sized) NVRAM checksum (add w/o carry)
- ## 0000 if no checksum
- ## _S : Start of 1st/2nd/3rd/4th checksummed region
- ## _E : End of 1st/2nd/3rd/4th checksummed region
- ##
- ## Some BIOS versions do a checksum over the EISA NVRAM, some don't.
- ## If your BIOS does, there might be 2 or 4 regions included in the
- ## checksum. Set unused regions' start offsets to 1 and end offsets
- ## to 0.
- ##
- ##
- ## Examples:
- ## SET 0CA2,0CA3,0CA4,0F00,0F69,0F41,0F4D,0F60,0F68,0001,0000,0001,0000
