>> Aha! Have found some instructions for writing code that can be >> incorporated into the kernel to solve the timeout problem. What timeout problem ?? On this machine, a Zeos Pantera 486 "Rattler," the disk was retracting its heads (and, sometimes, even spinning down!) during periods of inactivity. FreeBSD's kernel threw a fit when it next tried to access the drive; the console was covered with ugly messages warning of timeouts in the disk routine, and everything hung for nearly 30 seconds. Not a good way to respond to a "green" computer system, which is common nowadays. > Could you be a little more specific ?? See my followup. --Brett
