If you ommit the apm support, then your machine can go to sleep and never wake up, or my network card (rtl8139 bodgey one) used to do that. Linux does actually look in the cmos structures when driving mfm/esdi drives, also for drives that don't support the IDE identify command or the ones you specify noprobe for. There is cmos reading code in hd.c I think. Linux also reads and writes the hardware clock; but most operating systems do. Regards, Kerry.
