You might want to recompile the kernel - I don't know for sure if it is supported "out of the box". There are flags to set on the wd0/wd1 controller lines to activate DMA, LBA, 32bit access, and such. Check the LINT file for more information. If you are unsure about how one goes about recompiling the kernel, check out http://www.freebsd.org/handbook/kernelconfig.html > Beforehand thank for the answer. > > Best regards, > Ilya Juravlev mailto:ilya@khrunichev.com Sure.
