TIL that the _OSI function serves a similar purpose to User-Agent strings. Not just that, but it has the same funny pitfalls:

Operating Systems fake being Windows via _OSI.
Browsers fake being each other via UA.

Some months ago, I turned on a Gateway GM5478, and it took suspiciously long to POST. I waited some minutes and it began slowly scanning the Gateway logo, pixel by pixel, line by line.

I suspect this happened because the clock-multiplier became no-op.

I still can't believe I witnessed such a "1 in a million" event. I wish I recorded it, because it only happened once
