IMHO you should never use > ISA-PNP without CONFIG_ISA. Linux PNP handles up to 3 protocols: ISAPNP -- useful only if CONFIG_ISA, independent of PNPBIOS and PNPACPI PNPBIOS -- useful only if acpi_disabled PNPACPI -- useful if !acpi_disabled drivers/pnp/isapnp/Kconfig appears to already have the dependency you're looking for to make sure that ISAPNP is not defined without CONFIG_ISA: config ISAPNP bool "ISA Plug and Play support" depends on PNP && ISA ------------------------------------------------------- This SF.Net email is sponsored by: InterSystems CACHE FREE OODBMS DOWNLOAD - A multidimensional database that combines robust object and relational technologies, making it a perfect match for Java, C++,COM, XML, ODBC and JDBC. www.intersystems.com/match8
