But I have some of consoles did work - response the key in after the keyboard pluged in after.=20 This is important. Almost all the servers in rack don't have keyboard collected unless we need to login to console. I couldn't plug in the keyboard then reboot the server to get access to the console. =20 Jessie Xu Unix Administrator jessie.xu@cryptologic.com desk phone: 416 545 1453 x 5618 Skype: Jessie.xu972 =20 -----Original Message----- From: Polytropon [mailto:freebsd@edvax.de]=20 Sent: Friday, April 16, 2010 10:26 AM To: Chuck Swiger Cc: Jessie Xu; freebsd-questions@freebsd.org Subject: Re: console no responding to key in.

If there was no atkbd: at boot time, attaching it later on will not introduce it to the system. As you said, Chuck, it may even destroy hardware to try to do so, leading to the fact that you have a server with *no* AT keyboard at all. I've already seen that with older systems not using a resettable fuse. > In such cases, trying a USB keyboard instead might work better. Jessie Xu initially said he was on FreeBSD 4. If I remember correctly, what you suggest isn't possible in the default configuration. Maybe a USB keyboard will be detected, causing a ukbd: message in the log, but that's all - no input from it. You need to type "kbdcontrol -k " to switch over from the default AT keyboard to the USB keyboard, there's no kbdmux in 4. As for servers, trying to connect via serial console seems to be the standard way. Otherwise, attach keyboard and monitor to the system while the power is off. REALLY OFF (pull mains plug to be really sure - see PS/2 defect mentioned above). -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
