Who said that the Promise Ultra100 card wasn't supported by Linux-Mandrake?
It works a treat on my machine, with kernel 2.2.17-0.24mdk and
2.2.17-21mdk. With 2.2.17-0.24mdk, I have to append "ide2=0xd400,0xd802
ide3=0xdc00,0xe002" to lilo, but 2.2.17-21mdk doesn't need it. "Autotune"
in lilo will make it hang on partition check during boot. I don't use any
drive optimisations.
