wbsio(4): Winbond Super I/O driver for lm(4) over wbsio(4) attachment
Hi,
The wbsio(4) driver allows one to attach lm(4) on non-standard IO ports,
or, alternatively, discover the said non-standard ports, so that an ap-
propriate lm0 configuration line could be devised for the configuration
file of the kernel.
Best regards,
Constantine.
