I have an adaptec 1520 controller. According to the FreeBSD manuals it's slow partially because the 1520 doesn't have DMA support. That may have been true on older 1520 models, but currently they have a jumper to select either polled mode or DMA. Can I used the DMA function with FreeBSD? The aic driver example just shows an interrupt and port, not a drq. Can I use the drq keyword? Or can I used the aha driver with the 152x to get DMA? The card does support DMA. Any help is most appreciated! Thanks in advance. PS - please reply to jlwest@tseinc.com as I'm not currently on this list. THANKS!
