>Description:
5.3Beta7 hangs right after displaying the system memory information. I'll guess that the 2-CPU motherboard, when there is only one cpu installed, is confusing the SMP probes.
The Tyan S1668 motherboard is rather old (circa 1996), but it still runs FreeBSD 4.3 just fine. Only when I try to boot 5.3 from the three boot/kern1/kern2 floppies are there problems.
Here are the verbose boot messages. It does not continue after the "avail memory" line.

If there is anything I can do to gather more data for you let me know. Otherwise I'll try again with the next 5.3 release.
