VT8233 PCI to ISA Bridge This is a surprising result, as the VT8233 datasheet didn't mention the I2C block mode. I'll add this model to the list. This also suggests that the VT8233A may support it as well - if someone could test that. I have to admit I don't know exactly in which order the different south bridges were designed and released by VIA. I think the following order is correct: VT82C596 VT82C596B VT82C686A VT82C686B VT8235 VT8237 But I don't know where the VT8231, VT8233 and VT8233A should be inserted in this list. If anyone can tell me... Could you try running "i2cdump 0 0x50" and "i2cdump 0 0x50 i" (with the patch still applied), and compare both the outputs and the time each command takes? You should see similar outputs, but the second command should be magnitudes faster. This would confirm that the I2C block mode works as intended on your VT8233 chip. (0 and 0x50 may be different values on your system, please adapt depending on where in the sysfs tree the eeprom file appeared.) Thanks for the tests. -- Jean Delvare
