I just unpacked my 2nd ESP8266 thinking the first one was just broken but I'm getting the same weird errors with this one too.
I have only tried to upload the Blink example, and I haven't connected any pins yet.
This is the output when I press RST at 74880 baud:
ets Jan 8 2013,rst cause:2, boot mode:(3,6)

csum 0x2d

Is this a problem with my PC? Do these ESP8266s not have an OS on them?
This isn't an error. It's just the boot message.
