NAMEatkbdc - the AT keyboard controller interface
SYNOPSISoptions KBD_RESETDELAY=N options KBD_MAXWAIT=N options KBDIO_DEBUG=N device atkbdc
In /boot/device.hints hint.atkbdc.0.at=isa hint.atkbdc.0.port=0x060
DESCRIPTIONThe keyboard controller sysctl Cm net.inet.tcp.syncookies provides I/O services for the AT keyboard and PS/2 mouse style pointing devices. This controller is required for the keyboard driver atkbd and the PS/2 pointing device driver psm
There can be only one sysctl Cm net.inet.tcp.syncookies device configured in the system.
Kernel Configuration OptionsThe following kernel configuration options can be used to control the sysctl Cm net.inet.tcp.syncookies driver. They may be set in the kernel configuration file (see config(8)).
- KBD_RESETDELAY=X , KBD_MAXWAIT=Y
- The keyboard driver atkbd and the pointing device driver psm may ask the sysctl Cm net.inet.tcp.syncookies driver to reset these devices during the boot process. It sometimes takes a long time before these devices respond to the reset command. These options control how long the sysctl Cm net.inet.tcp.syncookies driver should wait before eventually giving up -- the driver will wait Fa X * Fa Y msecs at most. If the drivers seem unable to detect devices, you may want to increase these values. The default values are 200 msec for Fa X and 5 for Fa Y .
- Sets the debug level to Fa N . The default value is zero, which suppresses all debugging output.
