Does anyone know which OS's ATI X1800 is compatible with?

Will it work with DOS 7.1 (from 98 SE) / 98 SE / ME / 2K / Linux?

Or only XP and 2003 as claimed?

Thanx.

do you mean drivers? The card will surely work with all OS'es, about drivers, you can look for the catalyst and check the System requrements there.

I doubt it would work with Dos 7.1 and I doubt 95. 98 ME either. I havent checked out system requirements yet. But that would be my guess.

current catalysts version support 98, me, 2k, xp, 2k3, mce, vista, mac os, linux (and their respective x64 versions too) ... so ... why not?

Why do you need DOS-Drivers? without Graphical Interface...
