Hitchhiker's Guide to Openbsd

pc0 - the standard keyboard and video display of a i386 system. 
❍
com0, com1 - Two serial ports 
❍
apm - Advanced Power Management BIOS functions 
❍
636k 190M - The amount of conventional (below 1M) and extended (above 1M) memory it found 
❍
fd0 hd0+ - The BIOS disk devices found, in this case, one floppy and one hard disk. 
The '+' character after the "hd0" indicates that the BIOS has told 
/boot
that this disk can be accessed via 
LBA. When doing a first-time install, you will sometimes see a '*' after a hard disk -- this indicates a disk 
that does not seem to have a valid OpenBSD disk label on it. 
4. Kernel: 
/bsd
: This is the goal of the boot process, to have the OpenBSD kernel loaded into RAM and 
properly running. Once the kernel has loaded, OpenBSD accesses the hardware directly, no longer through 
the BIOS. 
So, the very start of the boot process could look like this: 
Using drive 0, partition 3. <- MBR
Loading.... <- PBR
probing: pc0 com0 com1 apm mem[636k 190M a20=on] <- /boot
disk: fd0 hd0+
>> OpenBSD/i386 BOOT 3.15
