I'm newbie in OpeBSD. I can't find options like CPUTYPE in
FreeBSD /etc/make.conf. And when I'm compiled machine-dependent kernel
with everything disabled except ethernet card, and some pci devices, but
boot message shows me USB not configured message. Where I can disable it
and where I can configure CPU type? And i found out that when compiling
kernel it uses -march=i486 flag, and why?
