Hi, I want to program my motherboard's sensor ( http://www.winbond.com/PDF/sheet/w83627thf.pdf ) but I don't know how programs like SANDRA and SpeedFan knows it's on port 0x290
![]() This device is on LPC bus and a read it must be treated as ISA bus but I donĀ“t know how to scan it without risking to writing to another device. Any suggestions of where can I read something about this? |

Because I am better in disassembly than in assembly, I use another method to make monitors on my mobos - on my old MB Abit KT7A as well on new MB Asus A8N I have Award Bios.
Get bios from chip by included flashutil, then split it to LHA or LZW archives, unpack them and look for something like mov al,'R' call something_what_display_al mov al,'P' call... mov al,'M' call... (this display fan RPM) hiew.exe is good for playing with raw bios binaries. try to search mov al,'R' as hexa opcode (2 bytes) by e.g. hiew.exe you must disassemble code in near part and you will find what you want If you have AMI bios, this couldn't help you. If I remember correctly, it was near offset 00009600 (it may differ not much in other award bioses) in first LHA archive in A8N award bios - for first LHA just rename bios to filename with extension LHA and unpack it e.g. under Windows Commander, then try to google for hiew.exe if you don't have it.
