You need to have done a `make install', issued a `depmod -a' and made sure `/etc/conf.modules' (or `/etc/modules.conf') contains the appropriate module path before you can use some functions of this utility. Read doc/modules for more information. Also, you need to be `root', or at least have access to the /dev/i2c[-/]* files for some things. You can use prog/mkdev/mkdev.sh to create these /dev files if you do not have them already. If you have patched your kernel and have some drivers built-in you can safely answer NO if asked to load some modules. In this case, things may seem a bit confusing, but they will still work. BIOS vendor (ACPI): COMPAQ System vendor (DMI): Compaq BIOS version (DMI): P25 We can start with probing for (PCI) I2C or SMBus adapters. You do not need any special privileges for this. Do you want to probe now? (YES/no): YES Probing for PCI bus adapters... Use driver `i2c-piix4' for device 00:0f.0: ServerWorks OSB4 South Bridge Probe succesfully concluded. We will now try to load each adapter module in turn. Load `i2c-piix4' (say NO if built into your kernel)? (YES/no): YES /lib/modules/2.4.20/kernel/drivers/i2c/busses/i2c-piix4.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including inva lid IO or IRQ parameters /lib/modules/2.4.20/kernel/drivers/i2c/busses/i2c-piix4.o: insmod /lib/modules/2 .4.20/kernel/drivers/i2c/busses/i2c-piix4.o failed /lib/modules/2.4.20/kernel/drivers/i2c/i2c-piix4.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including inva lid IO or IRQ parameters /lib/modules/2.4.20/kernel/drivers/i2c/i2c-piix4.o: insmod /lib/modules/2.4.20/k ernel/drivers/i2c/i2c-piix4.o failed /lib/modules/2.4.20/kernel/drivers/i2c/i2c-piix4.o: insmod i2c-piix4 failed Loading failed... skipping. Do you now want to be prompted for non-detectable adapters? (yes/NO): To continue, we need module `i2c-dev' to be loaded. If it is built-in into your kernel, you can safely skip this. i2c-dev is not loaded. Do you want to load it now? (YES/no): Module loaded succesfully. We are now going to do the adapter probings. Some adapters may hang halfway through; we can't really help that. Also, some chips will be double detected; we choose the one with the highest confidence value in that case. If you found that the adapter hung after probing a certain address, you can specify that address to remain unprobed. That often includes address 0x69 (clock chip). Some chips are also accessible through the ISA bus. ISA probes are typically a bit more dangerous, as we have to write to I/O ports to do this. Do you want to scan the ISA bus?
