Now I get as far as "Welcome to > FreeBSD" before the system hangs. If you're running an ISA or ISA/VLB bus, check the clock divider in the BIOS setup. Make sure that the ISA bus does not exceed 8.00000 MHz by even a little bit. Actually, most peripherals will run at, say, 8.333, but there are some that won't. When the data throughput becomes high, any error will show up as a loss of synchronization. I first had this happen to me with net cards running DOOM 2 deathmatch via IPX. Slowing down the bus solved it. -- Ken Are you interested in | byte-sized education | http://www.play-hookey.com over the Internet? |
