## 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 ; SIS DETECT 0CA2,0CA3,0CA4,0F00,0F69,0F41,0F4D,0F60,0F68,0001,0000,0001,0000 ; SIS-EISA 12/12/91 SL 486VE DETECT 0CA2,0CA3,0CA4,0F00,0F94,0F41,0F4D,0F60,0F68,0F70,0F7B,0F90,0F93 ; Generic SIS without checksum DETECT 0CA2,0CA3,0CA4,0F00,0000,0000,0000,0000,0000,0000,0000,0000,0000 ; OPTI without checksum DETECT 0C08,0C01,0800,0F00,0000,0000,0000,0000,0000,0000,0000,0000,0000 ; Texas Instruments TI EISA/S without checksum DETECT 0C00,0C01,0C02,0F00,0000,0000,0000,0000,0000,0000,0000,0000,0000 ; ## End.
