 Until linux supports ibm thinkpad controls like ps2.exe, it is recommended you keep a small bootable partition (10-100MB for a DOS partition). You will need this if you want to change or find out irq, mem address, and dma settings.

 For '''PCMCIA''' support you have to load the ''yenta_socket'' module and change the configuration file <tt>/etc/conf.d/pcmcia</tt> (replace <tt>PCIC=i82365</tt> with <tt>PCIC=yenta_socket</tt>).
 For '''Frame Buffers''' support, do '''NOT''' load any frame buffer drivers besides vesafb. Do NOT even load vesafb-tng. Even though the video card is a trident card, the tridentfb does not work. It will produce a flickery screen. All you want to do is compile vesafb into your kernel or as a module, then add vga=791 to your boot line. Do not even bother with video=mtrr or any other options. VGA=791 is all you need for 1024x768 frame buffers support.

 I don't actually know how many fans are in there, but I know that when I did not turn on the fans manually, acpi -V showed readings as hot as 93 degrees Celsius when compiling and CPU intensive operations.
