Where did that BIOS come from... I can't try it as I am still waiting for my replacement BIOS chip.
I asked for tech support from Epox regarding the lockups and they said:
Unfortunately we do not provide Linux support; if Nvidia knows about the issue, hopefully they will issue revised drivers.
I know it's a "beta" BIOS, but I can't find any beta BIOS' on the epox ftp archive...
I don't mean to say that I can't download it from ocworkbench, just that I am curious as to how/where they get the new BIOS' from.
