Re: firmware and OS drivers dichotomy
Hi,
Of course VBE doesn't help with the "doesn't work" problem. It does help for the "ugly/low resolution" problem (but there's still a "half-assed video ROM doesn't support the monitor's native resolution" problem).
Cheers,
Brendan
For the computer I'm currently using; the BIOS leaves the first video card in a "VGA compatible" state but not the second video card, and because these video cards are "dual head" it means that only one of the 4 possible monitors could be used in a "VGA compatible" way. While this isn't a large enough statistical sample, it implies that a VGA driver would only work in 25% of cases (for a limited definition of "work" that doesn't include any video mode that any user will actually want to look at).Combuster wrote:A VGA driver expects that the device conforms to the VGA standard, which 99% of the desktop video cards out there are.

For all things; perfection is, and will always remain, impossible to achieve in practice. However; by striving for perfection we create things that are as perfect as practically possible. Let the pursuit of perfection be our guide.
