Where can I find the driver for the Compact Flash slot?

[3to4]

Hello, I would like to have some advice.
I clean installed Windowx XP in my X32 (2672-M8J). Everything went well so far. Except that there is a question mark before Mass Storage Controller in the device manager. I presume that this is the compact flash slot. However, there doen't seem to be any relevant driver in IBM website. I ran Software installer in vain. Can someone advice me where I can find the driver?

[Sorry. I was stupid.
Actually, I tried an old Panasonic CD-RW drive, and when I removed the drive, I left its interface PC card in the PC card slot, which was giving a mass storage controller with a question mark in the device manager.
