Unfortunately, it's missing the earliest messages. I'm especially curious if your machine claims to have an ELCR, which would be output to a serial console very early on. I'll commit the current workaround for your mptable and work up a patch to use the ELCR if it exists for ISA busses, not just EISA, maybe that will help. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
