[This is with FreeBSD 4.11-RELEASE]
I would like to arrange that the ATA keyboard works even if the machine is
booted without a keyboard, but one is subsequently plugged in. My
understanding is that the default behaviour of probing for the keyboard is
set here in the kernel configuration:
device atkbd0 at atkbdc? irq 1 flags 0x1
^^^
# `flags' for atkbd:
# 0x01 Force detection of keyboard, else we always assume a keyboard
So I tried putting
hint.atkbd.0.flags="0x00"
in /boot/loader.conf, but that didn't make any difference.
Looking at sys/dev/kbd/atkbd.c, I see:
/* XXX: a kludge to obtain the device configuration flags */
if (resource_int_value("atkbd", ATKBD_DEFAULT, "flags", &i) == 0)
flags |= i;
Does this mean that it's impossible to clear this flag without recompiling the
kernel? If so, is there a reason for this?
TIA,
Brian.
