Obviously I bumped into this problem. BTW, I plan to purchase a Promise Ultra66 controller for connecting four ATA-66 disks and configuring a RAID-5 device using Vinum (4.1.1-STABLE). Greg, What do you think about this configuration? Should it perform well? The machine has a Pentium Pro 180 CPU and the 440FX chipset. I want to use it for setting up yet another FreeBSD mirror.
