<p>The keyboard controller (<var class="LITERAL">atkbdc</var>) provides I/O services for
the AT keyboard and PS/2 style pointing devices. This controller is required by the

# syscons is the default console driver, resembling an SCO console

</pre>

<p><var class="LITERAL">sc</var> is the default console driver and resembles a SCO
console. Since most full-screen programs access the console through a terminal database
library like <tt class="FILENAME">termcap</tt>, it should not matter whether you use this
or <var class="LITERAL">vt</var>, the <var class="LITERAL">VT220</var> compatible console
driver. When you log in, set your <tt class="ENVAR">TERM</tt> variable to <var

console.</p>

</pre>

<p>This is a VT220-compatible console driver, backward compatible to VT100/102. It works
well on some laptops which have hardware incompatibilities with <var
class="LITERAL">sc</var>. Also set your <tt class="ENVAR">TERM</tt> variable to <var

driver might also prove useful when connecting to a large number of different machines
over the network, where <tt class="FILENAME">termcap</tt> or <tt

often not available -- <var class="LITERAL">vt100</var> should be available on virtually
any platform.</p>

<div class="NOTE">
<blockquote class="NOTE">
<p><b>Note:</b> If you have an internal modem on <tt class="DEVICENAME">COM4</tt> and a
serial port at <tt class="DEVICENAME">COM2</tt>, you will have to change the IRQ of the
modem to 2 (for obscure technical reasons, IRQ2 = IRQ 9) in order to access it from
FreeBSD. If you have a multiport serial card, check the manual page for <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=sio&sektion=4"><span

information on the proper values to add to your <tt

chips) use IO addresses in the form of <var class="LITERAL">0x*2e8</var>, and since many
cheap serial cards do not fully decode the 16-bit IO address space, they clash with these
cards making the <tt class="DEVICENAME">COM4</tt> port practically unavailable.</p>

<p>Each serial port is required to have a unique IRQ (unless you are using one of the
multiport cards where shared interrupts are supported), so the default IRQs for <tt

<p>MII bus support is required for some PCI 10/100 Ethernet NICs, namely those which use
MII-compliant transceivers or implement transceiver control interfaces that operate like
an MII. Adding <var class="LITERAL">device miibus</var> to the kernel config pulls in
support for the generic miibus API and all of the PHY drivers, including a generic one
