Dark Mantis, apologies if this has been mentioned elsewhere, but, just for the record, would you be able to tell us whether you have any direct relationship/comm channel with Gigabyte, or receive any financial, or product-related consideration from them for moderating this forum?
Having posted further up that I hoped the latest TouchBIOS build had fixed this "disappearing parameters" issue (and indeed it has behaved itself on my system for a number of weeks) I opened it tonight to find that, again, a raft of settings have simply disappeared from the application. This is in a context where my system has been rock stable and I haven't had to change any BIOS settings for ages.
I'm afraid Caterpillar makes a perfectly good point: it seems totally irrelevant for GGTS to send screenshots of their bench system to prove that their own iteration of TouchBIOS is currently functioning properly. They should be far more interested in the screenshots and other info that users have sent them showing the application misbehaving, and trying to find a fix for it, than trying to claim the problem doesn't exist. As far as encouraging Caterpillar to follow the screenshots, bottom line is that it shouldn't be necessary for end users to do anything other than install the application and run it. If it needs user-level tinkering to run on some configuration or other, that's a sign of immature/buggy product.
Back when I last contacted GGTS I was told that they couldn't reproduce this issue. It is clear that at the time I was far from the only person experiencing it, and it's even clearer now. Annoyingly, as a hardware/firmware developer myself I probably have the expertise and would have been happy to work with them to help diagnose it (and said so in my support request), but the responses I got left me with the feeling that the comprehensive info I took the time to collate and send simply wasn't read. I daresay others have been left feeling similar.
If it's happening out in the wild, on multiple installations, it simply isn't acceptable for technical support to claim that they can't reproduce it and stop there. They should either be trying harder to reproduce it on the bench, or contacting the affected users and trying to gather more detail on what's going on. You never know they might turn up some common factors on the misbehaving systems.
Have to say that while the construction and general operation of this board are excellent, the BIOS quirks (both TouchBIOS' problems, and the horrible power management bugs), and the (inadequate) response of technical support to these issues has, so far, been immensely disappointing, to the point where this aspect alone would push me in the direction of another manufacturer next time I'm buying. It's also left me thinking a couple of times about rejecting the board as defective.
If you do have any direct comms with the firm, a word in the right shell would probably be worthwhile - and no doubt welcomed by frustrated board owners.
