I don't work for FoxConn, but I do work for a hardware and software vendor. And here's some insight - as I have been in a situation similar to FoxConn - but being both the accuser and the guilty party at the same time
WHQL is kind of a big deal for hardware vendors. The main attractive is being able to add the "certified compatible with Windows" to your product box. Honestly speaking - having the logo there gives you *some* cred with users - at least, with Windows users ;)
So your competitors are nibbling at you, the product has to ship, and you need to have the logo in the box. What do you do? If you're already late to market, you hack. You install all the different flavors of Windows, check if it works - if it doesn't and crashes, well, some of that can be attributed to Windows itself. As long as you can install the OS and pass the certification, you're good, the product ships, you get your bonus and a pat in the back for delivering on time.
So say that during testing you DO install Linux and crashes - time for a reality check. If the product spec said "Windows WHQL is a must", and making Linux happy means not passing WHQL - tough luck. Linux won't run.
Or if "fixing the product so it passes WHQL" means "screwing Linux users", well, let me think about that ;)
Many engineers working on any given product would like to ship the best possible product - the one that has a 100% compliant ACPI, APM, TPM, you-name-it implementation.
But when time is short and the management chain is breathing down your neck . . . you do whatever it has to be done to be able to ship. And hope that once the product is out there, you WILL be able to go back and clean up the mess - and ship a BIOS upgrade. Everyone is happy.
Sadly, by the time the product shipped, you've been reassigned to other product - and you will only go back to the first one if the Windows crowd complains.
The solution is easy - Linux users to boycott the brand. But then again: if the mobo was designed to be sold to another company to be used as the basis for a product that will only run Windows . . . It isn't like you care a lot about losing the Linux business. This is only the reality - hard as it might seem.
And to the guy that originally found the bug: next time, remember that maybe the guy at the other side of the email exchange also thinks the situation sucks, but he's powerless to change it.
Because if even if he was provided with a full working patch for the BIOS (that doesn't break Windows compatibility), he might need to reapply for WHQL if he patches the BIOS - which means more $$$ and time spent on a product that is already shipping. So.
