Why do you want the BIOS to see the MicroSD? Do you want to boot from it?

If it's in a card reader you might try booting from USB.

What is the output from
Code:
lsusb
?

Are you attempting to boot Linux fom the SD card? I tried that and learnt that my laptop's bios didn't support that, so if you're trying to do the same it might as well be your case too. What's the output of
Code:
lspci -v
you should look for something like
