rebooting


This is a PowerMac system running netbsd-5 from yesterday with a Belkin 
PCI wireless card:

ath0 at pci0 dev 14 function 0
ath0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
ath0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 
36Mbps 48Mbps 54Mbps
ath0: mac 7.8 phy 4.5 radio 5.6

It'll be put into use soon, so if anyone has any suggestions or things 
you'd like me to test, please let me know.

Thanks,
John Klos
