Yeah. I have 2 machines. One machine is configured as...
IDE drive on primary as master
IDE drive on secondary as master
IDE CDROM on secondary as slave
This machine flys through the IDE probing which is great. My other
machine is configured as...
IDE drive on primary as master
IDE CDROM on secondary as master
I used to wait about 60 seconds for the probing until I patched
wd.c to reduce the timeouts. If I make the CDROM a slave it doesn't
get detected either.
Take a look at /sys/i386/isa/wd.c. Near the top there are 2 #defines
for TIMEOUT and RETRIES. You can play with these a bit to make the
probe not so painful. However don't cut them too short or it will
stop detecting your drives altogether. Also keep a copying of the
pre-patched kernel around just in case :)
Cheers.
