The BIOS setup is pretty much wysiwyg and very little opportunity for any settings changes. I really don't recommend it for open source OSen. The wireless device times out on its own eventually no matter what OS is running (although I never booted the thing with Windows; so I can't speak about that. I've tried several very recent Linuxes however and had the issue.) It does appear that the system has APIC. I have the following lines in dmesg: ACPI APIC Table: <TOSINV APIC > ioapic0 <Version 2.1> irqs 0-23 on motherboard ____________________________________________________________________________________ Sponsored Link $420k for $1,399/mo.
