  <H2><A NAME="9"></A>7. Checking Compatibility of Video Hardware</H2>
<p>In the following, we assume that you want to install XFree86/OS2 on a disk
drive with the letter Y: (which you probably don't have). Change the letter
in all commands accordingly.</p>
<p>
<ol>
<li>Obtain the package <code>Xbase</code> and install it from the root directory
of the Y: drive, by entering the following commands:
<blockquote><code>
<pre>
[C:\] Y:
[Y:\] cd \
[Y:\] unzip \path_of_package\Xbase.zip
</pre>
</code></blockquote>

</li>
<li>Edit your CONFIG.SYS file to contain the following line somewhere:
<blockquote><code>
<pre>
DEVICE=Y:\XFree86\lib\xf86sup.sys
</pre>
</code></blockquote>

Of course replace ``Y:'' with the correct drive letter.
</li>
<li>At this point, you may consider to add the variables required for
XFree86/OS2 as well, which will save you from one additional reboot.
Refer to section 
<A HREF="OS29.html#envvar">Adding Variables to CONFIG.SYS</A>
below.
</li>
<li>After adding the device driver entry to the CONFIG.SYS file, you must
reboot to install the driver. XFree86/OS2 will not work without this
driver.
</li>
<li>Start a full screen OS/2 CMD session and enter the following
command:
<blockquote><code>
<pre>
[C:\] Y:\XFree86\bin\SuperProbe
</pre>
</code></blockquote>

</li>
<li>This command will (normally) report important information about your
video configuration, i.e. the type of chipset, the available video
memory and the RAMDAC circuit available. Please write this down or
redirect the output of ``SuperProbe'' into a file by entering:
<blockquote><code>
<pre>
[C:\] Y:\XFree86\bin\SuperProbe &gt;filename
</pre>
</code></blockquote>

</li>
<li>SuperProbe can identify many more video cards than are supported by
XFree86. In some cases, SuperProbe unfortunately detects a wrong
card, often it claims to have seen a MCGA card which is some sort of
a fallback. Generally, if it is approximately right, there are only
few reasons for doubts; if it is totally off (e.g. saying it has
seen a ET4000, and you have a Cirrus card), you should report a
mis-detection as a bug to the given address. In all cases, please
take the few minutes and check the accompanying README.* files to
check for special precautions, options, or features of the card.
</li>
<li>If the README files tell you that your hardware is supported, please
obtain the rest of the software.
</li>
</ol>
