Re: what is pckbc0 ? installing netbsd of HP DL140G3

[Philip <subs%christiantena.net@localhost>]

Sorry, I meant with pckbc disabled.
I just tried your instructions (disable pckbc) on an old Pentium 3 at home
it killed the PS2 keyboard, but a USB keyboard still works (once the kernel 
picks it up)
The HP DL140 G3 has a PS2 keyboard connector, but of I don't yet know whether 
it's really PS2 or USB
inside (it might be just converted to USB on the motherboard).
Anyway that doesn't matter as the firewall will be in a rack on a remote site. 
A dead keyboard might
even be a security feature :-)
Is there a way to disable pckbc for the standard kernel once the machine is 
successfully booting
from harddisk?  some kind of boot loader option maybe?
would selecting serial bootblocks instead of bios bootblocks do it?
or do I really have to recompile the kernel?
thanks
