=== WD90C24 ===&lt;br /&gt;
This is a Western Digital video adapter&lt;br /&gt;
&lt;br /&gt;
=== Features ===&lt;br /&gt;
* Chipset: WD90C24, WD90C24A or WD90C24A2&lt;br /&gt;
* 1MB DRAM&lt;br /&gt;
* Interface: VL-Bus 2.0&lt;br /&gt;

|}&lt;br /&gt;
&lt;br /&gt;
=== Linux X.Org driver ===&lt;br /&gt;
This chip is not supported by X.org, the best you can get is 640x480 with 16 colors with the 'vga' driver as part of the X.Org distribution&lt;br /&gt;
&lt;br /&gt;
=== Linux XFree86 ===&lt;br /&gt;
The chip is supported by the &amp;quot;svga&amp;quot;-driver of the older XFree86 version 3 (3.3.6a is found in Debian Woody), though, resulting in 640x480 (or even 640x816 or 1088x480) at 256 colors. For the 750Cs, you additionally need to tweak the video ram by means of Michael Steiner's &amp;quot;tpdualscan.c&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
==== ThinkPad LCD ====&lt;br /&gt;
Display on the internal LCD works as long as you set the monitor settings correct.&lt;br /&gt;

==== External VGA port ====&lt;br /&gt;

=== Linux ALSA driver ===&lt;br /&gt;
This sound chip is supported by the snd-ad1848 kernel module. Use the following options line when loading this module:&lt;br /&gt;
&lt;br /&gt;
 options snd-ad1848 snd_index=0 snd_port=0x4e30 snd_irq=10 snd_dma1=0 snd_thinkpad=1&lt;br /&gt;
&lt;br /&gt;
If you're running Debian Woody: Its ALSA 0.9 hasn't this Thinkpad support yet. Hence, you need to recompile the kernel (2.4.18) including the soundcore module and adding ALSA 1.0.&lt;br /&gt;
