I've had problems with my audio and modem driver when I formatted my Sharp Mebius PC-MC30F laptop. Have resolved the problem with audio driver came from a japanese website via google search. I've got the modem driver by thinking that the manufacturer would install the same modem with other model so, I try to install the driver for Model PCMC22 and it worked. Hope it will work for you also. Good luck!!! Email me for any comments.
