in my motherboard instruction designed for windoze-washed freaks (no real 
clear information..) it's said that:

"The orange PCI slot (PCI5) also works as a communication slot, which 
allows you to insert the communication card, such as wireless LAN card."

can anyone translate such a nonsense into english.

for those who like to buy amd64 system - my motherboard is Microstar 
MSI K8N Neo Platinum with NForce3 250Gb chipset. just think twice before 
buying ;)

anyway - performance is excellent if everything works.

my BIOS only allow to disable/enable use of interrupts for PCI slots. 
nothing else.

unfortunately x86-64 is still x86/windoze compatible and that's source of 
all problems.



it seems that FreeBSD works around this shit by just looking what devices 
are where and then allocating everything itself.

i'm just downloading FreeBSD-current to check too, they claim
even better support for this crappy BIOS in current.



my invisible builtin Nvidia network controller is still invisible 
including windows. this motherboard MAY be broken.
