Con, thanks a bunch for your illuminating clarifications. When I altered some options under APM, it worked. (My BIOS was too old for ACPI). As I enabled more functions, I can't really know what the trick was, but I suspect that it actually was compiling apm directly into the kernel instead of loading it as a module. The "CONFIG_APM_REAL_MODE_POWER_OFF": was enabled all the time. BTW: Another "strange" thing I saw, is that my isapnp Soundblaster stopped working when I compiled a kernel with pnp BIOS. Something to try if this is a problem, I guess. --lars - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
