[newbie] kernel can't detect my ls-120

[tanghim]

Hi,

I have installed linux mandrake 6.0, but it can't recognize my ls-120 
drive.  The atapi floppy driver has been  installed as a module.  My 
ls-120 is in hdc.

messages after lilo:

...
hdc : Q, ATAPI UNKNOWN (type 17) drive
...
/dev/hdc: Device not configured

Anyone can help me to make the kernel recognize my ls-120?
