Note: This article pertains to Mac OS X Server versions 1.x, which were released prior to May 2001.
After starting up into Mac OS 8 it is necessary to use the System Disk control panel to set Open Firmware to start up into Mac OS X Server. However, if the QuickTime Streaming Server, or if the AFP Server is enabled, the command that the System Disk control panel tells Open Firmware to use is not appropriate.
During system startup the operating system reads the /etc/hostconfig file and determines if either of these servers is on. If either server is set to "YES", "srv = 1" will be appended to the command in Open Firmware and the computer will restart. The computer must restart in order for the new command to take effect. This new command configures the kernel so that it will work properly with these servers.
