This page is mostly here for my reference, and to vent as I couldn't find this information anywhere else (ie google).
-* Compaq Armada laptops
(as well as being extremely heavy
) have an Ensoniq ESS ES1869 !AudioDrive sound
-card in them
. These chips are SoundBlaster-compatible
, and can use sb drivers (under [Linux] and winblows). If you try
to set
the card to record at 44100Hz
, the most you can get
is 7954 Hz (samples per second)
. Possibly this could be resolved by using ESS
-specific drivers instead of SB drivers
, but it's not my machine to play around as root
.
+! [IBM] Thinkpad Laptop External Microphone
+Some
(or all?) thinkpads (such
as my Thinkpad 600
) have non
-standard microphone sockets
. They expect an external microphone to either be powered
, or
to make contact with a metal ring surrounding
the socket
, which supplies +5V, and give it to
the "tip" of the jack. This
is discussed at [http://www
.pc.ibm.com/qtechinfo/LWIK
-3QZJKZ.html?up=unknownuser]. If you plug in a regular
, un-powered microphone then nothing will happen
.

Genius MF3000II CardBus 100/10 Mbit ethernet card - this is a removable PC-card that uses a Realtek 8139 chip. The pcmcia-cs package with [Debian] 3.0 (Woody) wants to use the tulip driver that is not only hopelessly outdated but is known to be incredibly buggy on some cards (v0.91g I think the driver identifies as). Not useful AT ALL when you are trying to install Debian with a boot cd and expecting to use your network link to complete the install. The 2.4 kernel's 8139too driver works mostly, but craps out at high utilisation. My solution was to download Donald Becker's 8139 drivers from http://www.scyld.com/network/rtl8139.html which have been fine so far.
+! [IBM] Thinkpad Simple Boot
+Thinkpads in the 600-770 series have a "simple boot" flag which is really a PNP OS=no flag. You should ''disable'' it for Linux 2.4, at least if you want the sound to work. Change the BIOS by pressing and holding F1 ''before'' you power up the machine, and hold it until the BIOS screen appears. The simple boot flag is under the Quick Boot icon.

+! US Robotics Modem Power Supply
+I had two USR modems in a bag without realising that their power adapters were different voltages, and which went with which is not documented anywhere. So for the benefit of anyone who needs to know, the 20 volt pack works with the 33.6K Sportster Voice modem and the 9 volt pack works with the 56K Voice modem. ''Disclaimer: if I have got this wrong, and this causes you to burn down your house, it's not my fault.''

!Sound crashes your Acer Travel Mate laptop?
In /usr/src/linux/drivers/pci/quirks.c, (Line 488 in 2.4.19) you'll see a bunch of lines that look like this
