I want to post this here incase there will come useful information for others who have similar issues.
ok, here we go:
All the 3 latest nightly builds(pc iso) i have tried have failed upon booting. It stops right after i have chosen screenmode and the red mouse pointer show up in upper left screen.
The question is, are there any bios functions(i have an asus a7n8x-e motherboard & amd 2500xp processor) i should change to make it boot?
