On Thu, Feb 22, 2001 at 03:06:54PM -0800, Richard Johnson scribbled: | I wanted to mention, along these lines, that netbsd has a command | which can program the disk controller to enter "idle" or "standby" | mode after a number of seconds. The command is "atactl". I looked at | how this is done. It's using a set of controller commands which | apparently aren't supported under FreeBSD. The controller commands | are: | | #define WDCC_IDENTIFY 0xec /* read parameters from controller */ | #define SET_FEATURES 0xef /* set features */ | | #define WDCC_IDLE 0xe3 /* set idle timer & enter idle mode */ | #define WDCC_IDLE_IMMED 0xe1 /* enter idle mode */ | #define WDCC_SLEEP 0xe6 /* enter sleep mode */ | #define WDCC_STANDBY 0xe2 /* set standby timer & enter standby mode */ | #define WDCC_STANDBY_IMMED 0xe0 /* enter standby mode */ | #define WDCC_CHECK_PWR 0xe5 /* check power mode */ | Soren Schmidt sos@freebsd.org has atactl in the works. Wait a bit. :) Search -current archives from this and last month. -- +------------------------------------------------------------------+ | keichii@peorth.iteration.net | keichii@bsdconspiracy.net | | http://peorth.iteration.net/~keichii | Yes, BSD is a conspiracy. | +------------------------------------------------------------------+ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
