Here is a game I played in Windows 2000 Advanced Server that will probably work in FreeBSD. Tell the CMOS there is no drive on the IDE channel to which the big Maxtor is connected. Then boot on a bootable drive, and while it is installing the OS may discover and mount the Maxtor, as long as the BIOS isn't interfering. There is software for WIN98, but not FreeBSD or Windows 2000, for fooling an old BIOS into accepting a big UDMA drive. To boot on the big drive in FreeBSD you will probably need to install a UDMA 66 or 100 host adapter or replace your motherboard with one that supports UDMA 66 or 100. I recently saw UDMA 100 host adapters at a swap meet for $35, a good investment unless your motherboard is already due for retirement.
