If you mean that you have a CF single card reader, probably, depending on the Linux distro that you are using. If it is a newer version, such as Mandrake 9, my system will read a jump drive with no problem. From what I have gathered from the Pupply Linux site, the multicard readers will not, since Linux will only recognize the first slot. So, if you have a single card reader, with a 128 mb card, try it out. Linux will usually see it as sda1 or sda. Look at dmesg and see if the card is recognized as either sda1 or sda.
