Alienware Area 51m SD card slot.
 
I'm relearning Linux after a long sabbatical. (I mostly used it in
middle school in 98-99), and I'm hitting one wall that I think I just
need to be pointed in a good direction to solve this.


My SD card slot does not auto-mount or recognise on my Area 51m laptop,
and I don't know what device it should be showing up as. Is there a
command I can use to try and manually mount it? If not, what drivers
would I be looking for or setting up?

I've got one of these in my old Toshiba laptop. Mine doesn't work
either. lspci produces
Toshiba America Info Systems SD TypA Controller (rev 03)
for which so far as I can tell there is no Linux driver.

I just use my cards with a cheap USB reader which works fine.

The command dmesg should help here. If Linux can interface to it
then you should see something like this when you put in the SD card
(this will be towards the bottom of the messages):

What you are most interested is the sda (scsi disk A). The above may be from several
flash/SD/USB cards I was workign with recently.
