problems installing amiga os 4.0 with 4xEIDE'99 interface

[twizzle]

have you tried just putting the hd on the primary port (master)& your cd drive on the secondary port also master.

as with the fastata it doesnt like the hd & cd on the same cable,

[twizzle]

it is exactly the same with the fast ata, it only see`s the hd on the primary cable, no driver`s installed.

the os4 floppy loads the neccessary drivers to see the cd drive on the secondary cable (master)so that you can install os4 from the cd.
you have to read the instructions very carefully ?
as i took me 5 goes to install os4.
