I&amp;#39;ve two thousand PCs all same. And I want to change their Bios
settings. The change will also be same for all PCs. Anyhow, I&amp;#39;ve made
a keyboard, my problem finished.&lt;/p&gt;

&lt;i&gt;&amp;quot;Actually I ahve to change the Bios settings of many Computers
at a time, they are around 2000&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
There are PC utilities to do this.&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;I need an automatic keyboard that can send commands to enter
the setup and the to modify the setup and save changes and
exit.&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
This is a really bad idea!&lt;/p&gt;

&lt;p&gt;
Your 8051 unit will have no feedback whatsoever from the PC, so it
will not be able to detect if anything goes wrong, or one PC happens
to be slightly different, or...&lt;/p&gt;

&lt;p&gt;
You really need a PC-based utility to do this!&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to make an AT keyboard using 89C51.</title><link>https://community.arm.com/thread/112545?ContentTypeID=1</link><pubDate>Fri, 15 Dec 2006 01:37:51 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:70d3aa82-eb46-42b2-95f1-525c7a2f8ccc</guid><dc:creator>Maaz Qazi</dc:creator><description>&lt;p&gt;&lt;p&gt;

with windoes you can assign a com port &amp;quot;as the keyboard&amp;quot; and that
way you get a far simpler rig.&lt;/p&gt;
