Even Sloaris will not install correctly on this box with an ATA disk that size in it - the PROM is the latest update.  Unlike Debian (Linux kernel), NetBSD had no issue  with the disk at all, it created a file system over the entire disk and installed witout complaint - perhaps it should have?

Do you use the on-board IDE controller ? I don't think this controller has
problems with large IDE drives. However, I found sparc64/1.6.2 to be very
instable. lots of panics trying a package bulk build, running a 32bit kernel.
2.0 looks much better on this hardware.
