[edit] Definition of POST messages
There is a list of examples of beeps from some BIOSes. It should be enough to state that beeps are used, and then reference to other places, not to expand this article to cover all BIOSes.
[edit] BIOS and POST mixture
The article currently mixes the responsibility between the BIOS and POST a lot. As I understand it, POST is a part of the BIOS. Everything not part of the POST should be cross referenced the the BIOS article instead?
[edit] False information
Containing a lot of false information and blaming on another editor.
So, umm, is the Happy Mac, Sad Mac symbols part of a POST operation (or equivalent)? If so, that deserves mention here. There is also a Sad Ipod message.
[edit] Vandalism
Has anyone else seen this? Look at this page; this is what I see.
The original IBM BIOS reported errors detected during POST by outputting a number to a fixed I/O port address, 80. Using a logic analyzer or a dedicated POST card, an interface card that shows port 80 output on a small display, a technician could determine the origin of the problem. (Note that once an operating system is running on the computer, the code displayed by such a board is often meaningless, since some OSes, e.g. Linux, use port 80 for I/O timing operations.) In later years, BIOS vendors used a sequence of beeps from the motherboard-attached loudspeaker to signal error codes. haha
I've checked the entire article's wiki code, as well as the raw HTML source, but I can't find "haha" anywhere.
