Hey all,
EPOX has finally FIXED the freezing issue (hopefully I am not speaking too soon!) with a BIOS change!! As I said all along, in order to find a TRUE solution, the obvious method would be to look to see whether this problem has occurred before and to find out if a solution was available. Low and behold, after a quick Googling, one finds that Shuttle SN25P users had this same exact problem and a few weeks later there was a BIOS fix.
Well, for me it has been a few MONTHS later, but EPOX TW finally asked their buddies over there at Shuttle TW for the solution, and with their latest BETA BIOS, it appears that EPOX may have finally FIXED it! I have been stable for over 20 hours and this includes the overnight period where I normally wake up and find my computer froze at 5am or so. If you go to the Epox 9npa forums, you'll see that other people would agree with my sentiment, and they use other devices as well like USB HD's.
Being the nice guy that I am, I am trying to find out what was fixed so the word can be spread and my curiosity satiated. The only thing I have been told as far as what was fixed was that it was a problem with the Chipset BIOS rather than the CPU BIOS. I also know from using CBROM (a good BIOS utility) that the ACPI table and awardext.rom were also changed, although I don't know how. If Abit/ECS still is in business, I would have them try to get in touch with friends over at Epox or at Shuttle as that will be the fasted route to a solution for you all.
If I find anything else out, I'll let you know, but I just wanted you all to know that a BIOS fix is THE answer, and hopefully you'll get yours SOON!
IlluminiX
P.S. I don't believe it had anything to do with the ERRATA 123 or 124 which apparently Epox already patched awhile back.
