From INSTALL.TXT 4.2.1. My system hangs while probing hardware during boot, or it behaves strangely during install, or the floppy drive isn't probed. FreeBSD 5.0 and above makes extensive use of the system ACPI service on the i386 platform to aid in system configuration if it's detected during boot. Unfortunately, some bugs still exist in both the ACPI driver and within system motherboards and BIOS. The use of ACPI can be disabled by setting the ``hw.acpi.0.disable'' hint in the third stage boot loader: set.hw.acpi.0.disabled=1 This is reset each time the system is booted, so it might be necessary to set it permanently in the file /boot/loader.conf. More inforation about the boot loader can be found in the FreeBSD Handbook. -- Steve To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
