Re: Dual core install problems with ichiic
I looked through GENERIC after reading a bit and uncommented this #pseudo-device raid 4 I also added the following line after reading a tutorial. option RAID_AUTOCONFIG The OBSD FAQ indicates I have to uncomment the first line to get raid support. Am I missing something?

Actually, it was eaten by snakes... Well, actually, the motherboard just died after a few weeks without any special effects. Asus quality does not seem to be really high. The board is cheap and has 3 years warranty, though. I should be receiving a new board any moment. Now I hope the board didn't take the processor down with it. Note that the mpbios of this board has some quirks, which we (that is, kettenis@) had to work around. So while -current runs fine, 3.9 does not.

Gustavo Rios wrote: Does it make any difference to have dual core processor or not with openbsd ? Yes, the dual core can take advantage of the bsd.mp kernel. It's kind of like a dual processor if you like. It depend on the applications you run obviously, but in many cases, it does help.
Re: Dual Core
Gustavo Rios wrote: Does it make any difference to have dual core processor or not with openbsd ? I understand OpenBSD will use both cores, IFF your motherboard is mpbios-compliant, which most single-processor motherboards are not. I haven't actually tried this, so I could be mistaken.
