"For stability it must remain unchangeable, though configurable."
Amen!
Buggy drivers are bad enough. I can't imagine the support calls for buggy BIOS's.
Customer - "Um hello, support, my PC is going crazy."
Tech Support - "What's the problem?"
Customer - "Well, my CDROM is going in and out, the lights are flashing and the PC speaker is playing Mary had a little lamb and it won't boot."
