Please explain where you obtained said "livefs" CD. Every livefs CD I've tried (in qemu) has dropped me to a shell. Every "fixit" CD I've tried brings me to sysinstall and from there I drop to the shell after navigating the menus. > as for the apic vc acpi that was a typo > due to exhaustion, sorry bout that. Sure, but which one do you mean? I assume you mean booting with or without ACPI, which is an option in the boot loader. > > > motherboard so i couldnt even boot the debian installer cd. i also tried > > > booting the freebsd installer disks without apic but the same problem > > occurs > > > so i dont think its hanging because of the power managment. ACPI isn't just power management-- it's advanced _configuration_ and power interface. My understanding is that if present, FreeBSD talks to the ACPI on the BIOS to allocate IRQs and other resources. There have been bugs in the past when dealing with ACPI which caused the FreeBSD devs to include a boot option to disable it. If your system breaks w/o ACPI, then there's certainly a BIOS firmware problem. Have you tried the following test? Cold boot (from power off) to FreeBSD CD, disable ACPI from the menu, boot the kernel, then do a warm reboot and see if the problem exists. My sense is that if your first attempt from a cold start has ACPI enabled, the problem will persist for every subsequent warm reboot. -- Rick C. Petty
