I had been leaving The only difference of using this card vs. a plain IDE system is that it is a bus-master DMA controller. If this is causing you troubles and panics, it smells like your chipset might have problems with bus-masters, or the cache RAM is iffy. Try turning your cache into write-back (if you can), or turn it entirely off just to make sure. The AHA1542CP is supposed to work with 2.1.5 and 2.2 systems, i don't think it requires any specific settings. > (An e-mail copy of any posted reply would > be appreciated).
