Later tonight I am going to set up an informal clearinghouse list/wiki
for this issue so we can be more systematic about it.

I assume amd64 right?

burncd gives me no warnings (except on fixate [read time outs]) so this
is cosmetics I think (a local issue for you)

Like I asked the other person what is the actual performence of acd0
(150 or 300)?

I will have to look at this.

Don't know but this is defently a good starting place to gather base
data with (have sam run it also)

Ideally I should see the following on my machine (bios sees it) but the
above dmesg snip shows I don't:

500 GB HDD SATA/300
250 GB HDD PATA UDMA/133 (I have an other 250 GB I want to install as
soon this one is reconized)

I will try it tonight.
