I'm trying to install NetBSD 1.5 on an Ultra10.
	My disk is partitioned as such:

		a - solaris /
		b - solaris swap
		c - entire disk
		d - netbsd /
		e - netbsd swap

There's really not much point in having two swap partitions on the
same disk.

	I booted ftp://ftp.netbsd.org/pub/NetBSD/misc/iso/sparc64cd.iso and
	got the pciide lost interrupt messages and root could not be mounted.

The ISO image lacks a root fs.

	I put ramdisk.fs on /dev/rdsk/c0t0d0s4 and booted disk:e and
	got the same results.  Is there a ramdisk/miniroot that works?

The ramdisk.fs should work.  How did you boot it?  The 1.5 kernel
has a problem with the pciide driver not properly resetting the IDE
disk, so the kernel cannot access an IDE device that it booted from.
Maybe you're suffering from that problem.  This problem is fixed in
-current (which doesn't help you much).

	Is there a way to netboot the kernel and use the filesystem
	I copied to disk:e?  Suggestions welcomed.

You need to boot with the `-a' flag so you are prompted for a root
filesystem.
