IDE: Return zero when reading error register with slave selected (Justin Chevrier)
During hardware detection Openserver issues commands to slaves on both primary and secondary ports. We already return a zero for the status register in this situation but after reading the status register the Openserver installer proceeds to check the value of the error register. Currently we return the existing value in the register. This confuses the installer and it tries to access the slave units later on. When the command that gets issued later gets ignored the installer freezes. The patch below returns zero when reading the error register if a slave unit is selected. Openserver can now successfully be installed using the emulated IDE hard drive.
