Here's a bit of info on the Compaq LTE Elite and it's docking station

1) The CMOS setup utilities come by default installed on the hard
disk, on the third partition (but this is actually physically located
in the first area of the disk).  Don't delete them or you'll have to
pay the price of trying to find them on Compaq's somewhat incomplete
support WWW pages.

2) The normal way in which these utilities are run is by hitting
F10 when the cursor jumps back to the screen corner during boot POST.
The code that does this is apparently in the boot sector, so either 
install LILO on the partition boot sector, or if you do want to
use the MBR, create a LILO "other" entry.

3) You should probably make a setup diskette.  Two obstacles: 1) 
the stuff doesn't fit on one floppy so you have to figure out what's
the core set of files needed to run setup, and 2) the files are
not visible when booting a DOS operating systems due to the tricky 
way in which the partitions are set up.  Use a linux boot floppy
and mount /dev/hda3 to get at them.

4) Do not try to activate the boot-then-lock-keyboard password protection
option.  There is something about the way that linux/lilo drive the
keyboard that confuse this BIOS functionality.  This will result
in you not being able to type on your laptop.  The only way to get
a password prompt from the BIOS is then to insert a floppy in the
diskette drive and boot.  Enter the password you chose followed by a /
to remove the password.

5) The on-screen features manipulation popups don't work in all bpp
depths, so if you use them, test them under X.  I haven't yet poked
into the wd90c24 chipset to verify but I do believe the BIOS is using
the hardware mouse cursor sprite to render these images.

6) The docking station's ethernet card is actually an eepro, use 
that driver.  The SCSI card is an aha152x.  They are both actually 
on the same circuit board and can be configured from the BIOS utilities
if you have them.  The aha152x driver has a few problems.  If it hangs
during boot when some devices are attached, specify a 0 for the fourth
field of the aha152x boot parms, which means disable detachable devices.
The driver is also not very stable in normal use and can cause reboots.
I think this is that it might not be using bounce buffers and trying to
DMA above 16M on the ISA bus, as I've never seen it hang with 16M.
This was with kernel version 2.0.33.

7) Linux won't detect above 16M on this laptop, you must add a mem=24M
to your boot arguments.  You should probably also have an optional 
LILO image name where no boot parameters are provided, given the 
stability problems of the scsi controller.

8) There is a switch on the back of the docking station that allows
the docking station to swap IDE controller IDs with the laptop, thus
turning drives hda and hdb to hdc and hdd and visa versa.  If this
is done carfully, it can be used to boot a different Linux root filesystem
depending on whether the laptop is in the station or not, thus making 
configuration for different hardware a bit easier.

9) The inside of the docking station should have a sticker describing
the functions controlled by a dip switch block hiding behind the ISA
slots.  This can disable the docking station controllers or a/b c/d
switches and do a small amount of configuration of the integrated controllers.
Check these settings to see if they are the way you want them.

10) The PCMCIA chipset is an 82365
