[ltp] booting from sd card

[Hendrik-Jan Heins]

Hello,

This topic has probably been raised more than once already, but I
think it's worth raising it again:
I own a Thinkpad X61s (T7300). It contains an internal sd card slot. I
also know 3 people with an X61s 7500.
We all tried to get a boot from an sd card in the card slot, but to no
avail. Even worse: when selecting a boot device from the boot list
(F12), it doesn't even show up as a bootable device.
When I plug the same sd card in an usb card reader and plug that in
the x61s, I can actually boot from it!!! So why isn't this working
from the internal usb device? It can't be too difficult, as even the
Asus Eee can do it.

Does anybody know why this is not working?

best regards,

Hendrik-Jan
