I would just like to state that you guys have all been quite helpful. I have gotten FreeBSD/amd64 to work on both the Compaq Presario R3000 as well as my Gateway 7422GX. The Gateway and eMachines systems are based upon the VIA K8HTB and are much friendlier than their Compaq/HP counterparts. I am assembling a page of my experiences with both machines at http://www.cokane.org/amd64.html. I currently have: Gateway 7422GX - Working with ACPI, acpi_ppc, and nearly all hardware minus the BCM card Compaq R3000 - Working with ACPI, acpi_ppc, keyboard, cardbus/pccard, still some hardware watchdog timeouts The Compaq is coming along though. I'll post more info as it gets working better. In two days of hacking at it, it is working better now than any of the linux installs were able to work for the past year. -- coleman On Wed, 26 Jan 2005 11:37:31 -0800, Peter Wemm <peter@wemm.org> wrote: > On Wednesday 26 January 2005 08:49 am, Jung-uk Kim wrote: > > This is (hopefully) the last patch of the series, which fixes > > infamous '8254 timer not connected to IO-APIC' problem for nForce2+. > > Linux people had a hack here: > > > > http://lkml.org/lkml/2003/12/21/7 > > > > (Note: 2.6.10 has more refined version.) > > > > The attached patch requires the previous 'skip_timer_override' hack > > posted here: > > > > http://docs.freebsd.org/cgi/mid.cgi?200501192214.27401.jkim > > > > After the patch, you need to set 'hw.apic.skip_set_extint=1' from > > loader or loader.conf.
