Ok. Hey lets leave away such detail-teaching because I'm shure we both
know enough about all this details and technology (For me I have both
types gambling arround here - and also maintain a whole distro, too ...)

It was the first storry - my older Athlon.

ok - again.
I have a K6 on an ALI Aladin-5 board and an additional IDE controller
(Promisse). The onboard can be found as /dev/host0 and the additional
Promisse one appears as /dev/host2:
server1:~ # l /dev/ide/
total 0
drwxr-xr-x 1 root root 0 Jan 1 1970 .
drwxr-xr-x 1 root root 0 Jan 1 1970 ..
drwxr-xr-x 1 root root 0 Jan 1 1970 host0
drwxr-xr-x 1 root root 0 Jan 1 1970 host2

I works - but sucks, because I'm not able to predict the ide-controller
entries in /dev/ide/* because they seem (for me) randomly on each workstaion
I am ...
(All info from my very first mail ...)
The other bug is: On a Athlon-600 workstation based on an Irongate
board (Asus-K7M) I have to disable the first (primarry) channel of
the onbaord IDE controller, because it has problem with the UDMA-66
mode. But when I disable this channel, Linux generates a /dev/ide/host1
entry - No host0 entry is there. Sure it works - but sucks, too!
(Generates a very unstable feeling in me ...)
Thanks for keep reading ;)
