Subject: locked keyboard
Date: Tue, 21 Nov 1995 08:46:31 -0500	[thread overview]
Message-ID: <19951121134631.Lc_iajLke0-2ZvxfEcTfQ7VN8Kr1VD00COXD77Nyl5U@z> (raw)

i ran into this problem on a 386sx16 (a fairly old motherboard).
i've not seen it on any 486 here.
for the moment, i have changed kbd.c
as follows.

i changed the following assignment in kbdinit in the new kbd.c
	ccc |= Csf | Ckbdint | Cscs1 | Cmousedis;
to read
	ccc |= Csf | Ckbdint | Cscs1;
	if(x86() != 3)
		ccc |= Cmousedis;

this is sufficient to fix the problem here.
it's not ideal (because i don't yet know why this causes it to hang,
and i also don't know whether it really is
confined to [some] 386 motherboards or whether it
affects a particular keyboard chipset that
is also used on a 486.
